It's a limited edition Black that's ideal for studio use. The headband construction and ear pads made the fit comfortable. The semi-open back design has a neutral tone. The vocal positioning in mixing makes sure the nuances are reproduced. Each DT 880 Pro headphone is handcrafted in Germany and can be replaced if necessary. The single sided cable allows the headphones to be put on and taken off frequently without getting tangled, and soft ear cups provide for added comfort.
👤I upgraded to 880s after my pair broke from a few falls, and I don't regret it. I mix and master music, so I need headphones with a relatively flat response curve, and I'm happy to say that the 880s are very accurate and flat for most of the time. If you want headphones for casual listening, you'll find them boring and lackluster, but if you want mixing headphones, you'll find them great. There is a The soundstage is excellent and the 880s give a profound sense of width, making it much easier to work in the stereo field compared to closed-back headphones. I can pick up the direction of sounds in video games if that's important to you. There is a They're not very comfortable, that's the true problem with the DT-880s. If I don't have the sides adjusted right, the padding doesn't seem adequate, and the sides press against the crown of my head. You might want to only use these for a limited time, such as mixing, because wearing them for long periods of time could be annoying. This is an outstanding pair of headphones and I highly recommend them. There is an update. I have begun to resent the ergonomics of the headphones after using them for a long time. The headband is not good enough, and I've been able to shorten it in a way that doesn't cause it to grind against my head. The hard rim around the ear pads has begun to dig into my earlobe, causing a painful blisters, because most of the bulky weight of the headphones is resting on my ears. The sound reproduction is amazing and this is the best pair I've owned so far, but there is no comfortable way to wear them. If you're a heavy computer user and wear headphones every day, I recommend looking for a more comfortable pair. This pair is heavy and will stress out your neck muscles. The cable is coiled, which means that it doesn't like to rest on the floor, so I have a gripe with them. The upper end of the cable puts a lot of pressure on my neck, which is rather uncomfortable, and it also pulls at my headphones, which has caused them to topple to the floor a couple of times. I'm not sure why Beyerdynamic insisted on using a coiled cable, there isn't any benefit and plenty of drawbacks. I can't honestly reduce my rating since the pair functions so well. I can mix on these and that the mixes transfer well.
👤I bought a set of the Pros in black for use as my daily driver headphones and I wear glasses. I have worn headphones before, but they are the most uncomfortable I have ever worn. I used to use the ASTRO A40 TR headphones for 4 years with no issues stock or mod kit. People said they fit your head well and sounded great. I can't wear the Pros for more than half an hour because of head pain. They are not comfortable after a year of using these and have to be constantly adjusted. I tried getting a different pair of glasses, but it didn't make a difference. I called Beyerdynamic and they suggested putting a few books in between them to break them in for a couple of days, but that didn't do anything. I wear headphones that are loose and could fall off if I shook my head. I called the manufacture again and they told me that they would send me a band from the Premium version because it has a lower mounting pressure. I don't recommend these headphones for anyone that wears glasses because of the blue light blocking glasses. It's not enjoyable to listen to when you have terrible head pain, but they sound great when they are coupled with my Schiit Magni 3 amplifier and the Aorus Master integrated Dac. I ordered the HD6xx from Massdrop for the same price and hope they fit me better. I hope this helps someone else.
The audio is streamed with the highest level of detail and fidelity. The Q4 can fit with most home audio systems, but it does not support a microphone. A built-in Hi-fi headphone amplifier chip can drive most headphones with 16 to 200 Ohm impedance. A true plug-and-play digital audio adapter is easy to set up and install. 160mWRMS can be used as a volume controller for your computer. The mini compact D/A is safe for your audio system. There is an 18-month warranty on the optical cable and 5V power supply cable.
👤It's the same thing. If you're looking for the best DAC for music at this price, look elsewhere. This may be the best thing for you under $250 if you're in it for a DAC for general use. Update after nearly five months! I start with the good. Those knobs. It drives me crazy, all the people who use the devices insist that there's only one way to listen to things. If you want more bass, you should get more headphones. I don't make money and my collection still needs more variety. There is a I budget, but I'm all over the place. I have earbuds in my drawer. If you're on a low budget, there's a few Sony MH755s, Zero Audio Carbo Mezzo, and those Action Pies. There is a The Zero Audios work best with this DAC. I was surprised that the Zero Audios were not my favorite to begin with, but with this DAC they really shine. FiiO has some of my favorites so far, but I prefer other budget DACs for clear music and a good soundstage. The FiiOs are just boxes. They don't have knobs. The bass and treble knobs are kept at 75% of their total capacity. If I'm going to watch a movie, rewatch a movie, or something, I'll turn the treble knob down to 50%, and crank the bass up to about 90%. You feel like you're in a movie theater, and I just love it. There is a This isn't the best DAC for the highest quality music, but it is a good one for someone who wants to tinker with the sound, and has a high priority for how they modify their sound for movies and video games. This is a great example. The rifle in Far Cry 5 is loud. The only way to turn down the music in that game is to have bad sound control. I decided to lower the volume to 25% so that I could keep my volume where it was. The knobs can be useful. The only other one I know of that would do this well is the company name. $200 is the price for the Schiit Equalizer, and that thing alone. It's an equal opportunity. You would have to buy a DAC on top of it. There is a Maybe that's the best way to market this, as a gaming DAC, because I feel like the gaming community will appreciate this product more than the hardcore music community. There is a I'm not saying that gaming is bad, I'm just saying that they tend to be more in it for the maliable experience that pushes whatever media they are taking in more. I was immersed. They don't care if it looks good on paper, they care that it makes the experience more intense. There is a This DAC is half the price of some of the sound cards I see people buying and it can add that, but without the horrible distortion you'd find on gaming sound cards. There is a It's a simple little plug and play that looks nice on the shelf, does more than you'd expect, and doesn't break the bank. There is a If you want audio that sounds better than the bad thing you currently have but you don't need the best, then just buy this sucker. After almost five months, I've decided to pair this with the 1MORE Triple Driver in ears, and I'm very pleased with it. Absurdly bassy, but very little distortion with that combo. I've decided to raise this thing to a 5 star because I'm in listening bliss. I can't think of a part or accessory that has done anything for my computer. There is a I swear the title doesn't say "gaming DAC" anymore, and I know I said so, but it's not really a gaming DAC, it has weird sound positioning features. This does not have features involving audio enhancements. If you enjoy listening to great audio, this will be great for games. It doesn't have the usual features. I wouldn't want any special audio features for competitive games. I don't want anyone to think it has audio features when it doesn't. There is a This is still being used in February of 2022.
There are 4 screaming-loud stereo headphones. Control room monitor control w/ level control and monitor button. Multiple units are daisy chained by using 2 balanced 14” monitor outputs. The 1/3U rack-mount chassis is small. 2 balanced inputs.
👤Sound quality is acceptable for monitoring. I would give this product more stars, but for the fact that one of the two units I purchased came with an incorrect wired input cable, which caused signal loss. The wiring diagram on presonus' website is incorrect. The pin numbering scheme used by the XLR is wrong and the wiring is not correct. I was able to fix the problem myself, luckily one of the cables was wired correctly, and I used a meter to sort out the wiring. The units are working, but beware of the cables. I came up with a solution if you have the same problem.
👤Excellent build quality is what it is. If you want, you can mount this on a mic stand. The sound quality is excellent, with the entry level Shure SE 215-CL in-ear-monitors. This is an inexpensive alternative to get more expensive modules. There is a The included cable should have been longer. I don't see this as something for someone who is moving around a lot, or someone who is standing while playing. If you're standing or moving a lot, you should get a wireless system. If you try to use this with earbuds that are typically included with a cell phone, the power this thing puts out will distort them at low volumes. You need a pair of IEMs with this. Definitely recommended. Good build quality and sound.
👤I use the HP4 for home studio use to allow myself and the performer to monitor with ease, and it's great! I had a MicroAmp. Don't buy that. The power supply is loud and clear. Put that money towards something else. Presonus makes quality stuff at a great price point for those still early in their gear collecting journey. The HP4 looks nice, has a small footprint, sounds good, and does its job perfectly. This thing solved several of my problems, including the stupid HA400 that I had. I need something that will accept L/R input and allow me to run from the Scarlett's monitor outs until I can fix the hardware issue with my Focusrite interface. It's helpful when it comes to tight real estate on the power strip if you have a power adapter along the cord. You actually have access to more outlets if you have fewer bricks on the strip. I highly recommend this item to anyone working on a home studio setup.
👤The unit burned out. It was the 4th day of continuous use. It smelled like burning electronics, and it never worked again. It works much better with the four outputs after that, and should have been bought in the first place. The rating was changed to 1 star because of the failure. I had a cheaper unit that I would take with me to split headphones, but it didn't work well. Decided to spend more on this one. It's solid! It sounds great. It is very clear. It has its own volume/mute with the pass-through on the back. There is an on/off switch with the power supply. I'm going to keep this in my travel commentary pack.
The Premium Analog Circuit is a system for studio and stage applications. The NJM4580 operational amplifier and the high-power stereo amplifier are included in the Headphone Amplifier. Premium design and design delivers low noise floor and high headroom. Ultra-low-NOISE is what it is. The amplifier has a single stereo source and up to 4 pairs of headphones. Enjoy low noise music. There is four independent level control. This headphone amplifier has features such as high fidelity analog circuit, high power output, large dynamic, low distortion sound quality. Each person can control the volume of their headphones when you and your friends share an audio source. Saving energy is possible by using durable material. There are long wear potentiometers and switches. It's convenient to turn on/off the headphones power amplifier with a power switch whenever and wherever you please. There is complete equipment. The included 12V AC adapter is used to power. There is a Stereo Jack Adapter for free.
👤I thought to use this review to answer a question that might be common. The high impedance of the set worried me. The sound is very clean, and I get a nice volume boost. The main reason for this product is that I prefer to use my headphones through this amplifier even when I am not splitting the signal with other users. It's also a nice headphone amplifier. I like the way the inputs are on the back and the outputs are in the front. The knobs have no wobble. The power buttons light up nicely. 5 stars easy.
👤I was hoping for a better response from the $2K monitor controller than I got. There is a The Donner Headphone Amplifier has a degraded response. The two pairs of headphones I used degraded significantly. There is a The unit does amplify. It's built like a tank. This may be what you need if you're not concerned with pro-quality audio response. Despite the naming convention, I would add that it is not a professional.
👤This was what I was looking for. None of the newer ones transmit sound as loud as I wanted, and I own several headphones from over ear to in ear. Yeah. Yes. I am aware of ear damage and hearing loss. A loser. The device let me crank up the volume without adding noise or distortion. I like this thing. 5 stars for what it does and what it doesn't do.
👤It is not often that I post a review after receiving a product, but this is one of the times I think it is safe to do so. I needed the additional volume from the headphone amplifier to use the large screen TV. I was approved for a cochlear implant, but I opted out because I was told I was at risk for the surgery. I watch TV using closed caption. Even though I don't have the ability to hear sound clearly or understand it, the addition of sound enhances the experience. The sound level in my earbuds is too low. The addition of the Donner amplifier allows me to increase the volume on my TV so that I can hear some sound.
👤I like the feel and quality of the knobs, case, ports, and other parts of the build. The included headphones are a poor quality, feeling as if they're mostly plastic despite being solid-brass looking. There is a The audio doesn't seem to have any hissing or buzzing, but the quality is distorted to me. I don't think the audio is clear, the detail has been lost and the frequencies seem to bleed together. It's noticeable in the bass and deeper frequencies. Attempts to compensate for loss of bass and clarity through software was unsuccessful; increasing bass, reducing treble or modifying settings in any way actually make the distortions worse. If you're not into high definition audio or higher bit rate, this might not be a problem, but I think almost anyone could notice the difference. If I knew, I wouldn't buy this again. I would save for a studio ready version.
A practical single-sided cable. China is the country of origin. 3D gaming audio is very realistic. The best console gaming audio. The blaster acoustic engine pro.
👤I had been using the G5 for a while to get decent audio from my PC, as well as my TV through its optical out. The G6 improves on it. There is a It was already pretty good, and the sound is better. Playing Master audio tracks in Tidal and getting better separation of the instruments and better power is what makes playing Battlefield 1 so exciting. The sound is good. It makes clicky sounds if I turn on the 32 bit version and there is a hiss before audio starts playing. I'm happy with 24 bit 96khz. I don't take a lot of time off for that. Let's say 1/2 a star. There is a The best feature they added was the Dolby Digital decoding. There is a difference in watching TV and movies. It is very noticeable over the stereo pcm. There is a The streetlights on the front are worse than the original, you can't turn them off, and it's difficult to tape over. I use this in my bedroom, I sleep in my bedroom, and the computer provides enough power to keep the light on. They gave you the option of disabling the light on the top, but not the light by the dial. I have to cover it with black cloth before I go to bed. Please stop it with these lights. It is not necessary.
👤I bought this product for music production and gaming. I'm moving to 32bit from 16bit and this is the first time I buy a Soundcard that doesn't come with my mother board. I found out that most 32bit soundcards are not portable and cost between 250 and 400 dollars. There is a I thought it might be worth a try since I use Nintendo Switch and move a lot between PCs. -- There is a The device looks good, it has a smart button layout, and it has lights around buttons so you can know which mode is on when it's dark. You have to manually download the software from their website. It can be hard to re-download it on multiple PCs. Inside. You can switch between different sound settings for different games, movies, and music. There is a I can use my headphones like speakers to amplify the sound, it allows me to hear a lot more detail in my music than before. There is a I love the level of sensitivity it gives me to play around with, I feel like I can now master my tracks and harmony to a greater depth. The delay between pressing my keyboard to hear the result decreases potently if I use multiple heavy samples. The main material looks metallic but isn't, the device can get pretty hot after a few hours of usage, and the bottom of the device feels fragile and weak if you apply even minimal force on it. There is no option to change the adjustment wheel's color/color intensity, as far as I know, because the power button on the card means I cannot instantly hear my stuff without enhancements. The box has Warranty information that is very small and theusb is too short for a portable card. There are tips. You should use a longer mini-usb. You will need to adjust to some of your games, this card gives you depth and intensity you never played with before. You should find the right settings for your software and headphones. You need to manually change the sound quality on your PC's sound device to 32bit studio quality if some games don't support 32bit. I know of a few examples.
The headphones have a very precise bass and a powerful treble boost, which are not disturbing the vocals. These headphones have an impedance of 250 ohms and are great for the home or on the road. The spring steel headband gives you enough flexibility to fit nicely around your head. Un-Filtered Sound, Benchmark Performance. Individually tested and hand made in the USA. A 3.5mm auxiliary cable is needed to connect to a PC. The power supply is included.
👤The audio engineer who created the Objective2 amplifier is known as "NwAvGuy" and he is clever and brilliant. The philosophy behind this invention was to create an incredible bang-for-your-buck amplifier with benchmark performance that hits way above its weight class. He felt that people on a tight budget can experience what he felt was a true piece of audiophile equipment that doesn't come with the big pricetag of other headphones on the market. He succeeded at that. There is a Since he made his design open source, several manufacturers have jumped at the chance to reproduce his design, and to make various modifications in an attempt to cater to the wants and needs of headphone lovers around the world. I've been impressed with the version of the O2 amplifier from Mayflower Electronics. It made my HD6XX's come to life. The sound of these headphones is not comparable to how I heard them on my PC. Even the most difficult to drive headphones can be powered by this versatile little amplifier. It has a clean sound. Its neutral and uncolored. The background is black. Dead quiet. No annoying buzzing or humming that I could hear, even at high volume levels in between songs. There is a The Mayflower O2 is well-built and sleek. It has a 10 year warranty. The units are assembled and tested in-house in the USA, which is not the case for some of its competitors versions. I like supporting local businesses and this one is close to where I live. I've already had great experiences with their customer service and would happily buy from them again. I encourage buyers to reach out to them if they have any questions or are looking for different options. They've made a fan out of me.
👤This amplifier is amazing. It is clear and reproduces music accurately. I am using a pair of headphones that are 80 ohm and I can't turn the volume up as high as I would like. The app is clear, free of distortion, and non colors so as to listen to what the artist and the mixing team intended for you to hear. I am very happy with my purchase. This is the one app that you should look for. You will be blown away by buying it.
👤I love death metal. I can say that the sound quality was greatly improved by this amplifier and headphones. I use them to play games and watch movies. Absolutely worth the money. I would recommend this amplifier to anyone. I didn't know what I was missing with the headphones.
👤This is a great product. I use the O2 amplifier to amplify the sound of my audio files on my computer. The bass guitars and tympani sound the same. I use it to listen to a wide variety of genres on the Grado line of headphones and I couldn't be happier. Excellent definition and naturalness. The sound is much better than using a DAC. There is a lot of volume. There is a This is a steal.
There is a package with a DC 32V 5A Power Adapter for free. If you want to get the maximum power of 300W, you need to buy a power adapter that uses DC 48V and current is over 7A. The design of the spark is a DC coupled topology from input to output, meaning it has no capacitors in the signal path to detract from the sound. The spark uses very small mosfets for output power and low noise audio jfets for its differential input stage, which makes it an exceptional design. The spark has a clean pre-amp output, which can be used with powered speakers. An ideal configuration for an entry level desktop set up performs well above its price point. If you want to be where the music wants you to be, you will be put there at a very affordable price. THD+N is composed of 1 Vrms (20mW) and 0.05% THD+N. 5 Vrms (530mW)- 0.035% THD+N. 10 Vrms (2.12W)- 0.065% THD. Monoprice has a 1 year repair warranty and a 30-day money back guarantee, so you can buy with confidence.
👤I have been doing reviews on my purchases for the past two hours. I will finish this one quick because I'm a little burnt out. I'm tired because this amplifier deserves a well thought out and lengthy review. This goes. It was short and sweet. This is the best amplifier on the market. The schiit magni 3 is the only competitor. There is a The power is: 1) schiit magni 3 2) liquid spark and 3) atom. The build has liquid spark and atom sound quality very close to each other. I'm talking fractions that are close. Not even that noticable of a difference, but the atom is slightly better than the other two. The amplifier is all power and build quality, but lacks a clean sound. The schiit magni 3 might be your best choice if you have headphones that need a nuclear reactor to power them. The liquid spark is miles ahead of the magni 3 in sound quality. There is a tight race for the best budget amplifier. The liquid spark has more power, better build quality, and less clean sound than any other amplifier, so I have to give it the best budget amplifier award. This is a very impressive amplifier that drives almost all headphones. I can't tell you enough about what you are getting. Absolutely fantastic. You can't really go wrong with any of the three. If you are looking to buy a $100 Amp, I think you will find that all three of the Amps are great choices, but you need to think about your needs, and if you are a snob about your equipment, all three of the Amps are great choices. It comes down to this. If you want the absolute cleanest sound and don't care about power or build, then you should get the jds Labs atom. If you don't mind a clean sound and want heavy power, then you should get the schiit magni 3. If you want to meet somewhere in the middle and have the best of both worlds, then get this liquid spark. Hope this helps you make a decision. Enjoy my fellow audio lovers.
👤I've had the album for a couple of weeks. My main goal is to add another data point for those that may still be undecided. I was on the fence. Monoprice's first venture into serious headamps is not trustworthy. I was expecting a lot of reports of shoddy build quality, but it kept me from pulling the trigger. A huge thanks to the people that took the time to talk with me and push me over the edge. I think that moving up from the Schiit Lyr 3 meant that my DAC was also going from balanced use to SE use. That means that any improvements I hear may be a mix of the Amp and Gumby. I can't reliably distinguish between the two. Gumby A2 is all you can listen to. --Packaging The packaging of the amplifier I ordered from Monoprice was terrible. The amplifier is bouncing around all over the place because of a huge box with two packing bubbles. I was impressed with the box itself. It feels right for $700 or $770 now. Everything is packed inside a nice bag for the amplifier. I know, who cares? It's all about the sound. The big question here is value. $700 is a lot for someone like myself and I want to feel like the money was well spent. Monoprice has done well here. It feels like a high end product. Quality-- When the prototype pics were released, I thought it was hideous. It's nice in person. The case is well-aligned and everything feels solid. The dark gray on the front plate blends into the black body nicely, making the whole thing look very sleek. I don't know why the left and right balanced inputs are switched. When I heard the channels switched, I was shocked. I always tell my students to read before they answer a question. I was not able to read the L & R printed above the sockets. That's on me. The construction is made of metal and has a good weight. It feels like a lot. This is not a cheap toy. Tubes-- There is a The first time you install the tubes it will be difficult because of the tight sockets. The right tube went in without much difficulty. The left tube felt like it was against a wall. I realized the pins were crooked after I straightened them out. Things loosen up a little each time you swap the tubes out, but after 3 or so swaps everything is fine. It's not an issue because Tubes still take a little work to remove. Tubes are very easy to get in at this point. The stock tubes are very usable, but this amplifier responds very well to tube rolling. The stock tubes are clean sounding, but a bit dry. The sound is now dialed in perfectly to my preference after rolling some Amperex tubes. Sound-- This is a step up from the previous one. This isn't a critique of the Lyr. There is a The improvement in dynamics from the Lyr is obvious. The stage has been improved. The sound is very immersive and the instruments have their own spot in the mix. I don't think the soundstage is bad. I think it's decent compared to other Schiit offerings. The album is better. There is a Everything sounds natural and easy, without being boring. The sound is clean but not clinical. There is a What is the sound like in one word? Calculating. Enough said. Misc.-- This appears to be the biggest issue people have with this amplifier, but it's not an issue for me. You're stuck with 5x gain because there is no gain switch. I don't have a problem getting the volume exactly where I want it because it's smooth and accurate on the dial. I had the same experience with the Vali 2 and Lyr 3. Of course, YMMV. I only use the HD 650, so the more sensitive headphones will not have as much play on the volume knob. If this is an issue for you, it is worth your time to look into the methods. The sound of the amplifier makes it worth the extra expense. It runs hot. So what? It's not an issue. Conclusion There is a It seems like a good deal to me. I wondered if this would be a clear step up from the $500 and under category. It is. This is a re-design of the Liquid Crimson, which cost around $1500. The Liquid Platinum is a good deal. There is a It doesn't feel like much of a risk with a 5-year warranty because reliability is a question that remains to be answered. Upgraditis Status: Cured is the final conclusion.
Monoprice has a 1 year repair warranty and a 30-day money back guarantee, so you can buy with confidence. The amplifier circuit can work at a high voltage of 26V and the background noise index is excellent, thanks to the innovative circuit design. Excellent purity and transparency, and good dynamic range, can be found with wide frequency response extension. The sound is warm and delicate, with ultra-low distortion, and it was made using the original TI-NE5532 classical opamp and transistor expanding current circuit. Pluggable opamp sockets are convenient to upgrade different opamps. It's a smooth and mellow sound, suitable for listening to vocals or string music, classic or pop music, and even with unique charm when playing rock. Mini size with exquisite appearance and most cost-effective, brings big surprise for all audiophiles, easily to drive most headphones in the market, providing larger power, better sound field and details, very suitable for home/office desltop audio system use. It is easy to drive most high-impedance headphones with strong drive power.
👤Occasionally, all or most of us at least, wind up buying an inexpensive audio device, expecting that it will perform far below expectations, yet our curiosity based on having seen advertisements or word of mouth have persuaded us to complete the purchase. When I stumbled upon the Douk Audio U3 mini head amplifier on Amazon, I wondered if it would even approach marginal status. Since I have several budget level DAC's such as the Schiit Modi 3, I thought it would be a good idea to try out the budget head amplifier. I wasn't prepared to be impressed by the way it arrived. The U3 is built like a small tank and has an impressive front and rear panel layout. The craftsmanship of the U3 is very similar to more expensive products. The U3 has a pluggable op-amp sockets design, which allows one to experiment with different sound signatures, with op-amps being a dime a dozen now-a-days. There is a This is a "Head Amp" only. If you want to connect a DAC to a Head Amp which also has outputs on the rear of the device, that will not be possible. The U3 has no outputs so it will only be used as a headphones amplifier. The best compliment I can give the U3 is that it gives good head. The U3 and the M 100 were the first things I put together. Normally, I allow audio gear to go through a period of burn-in, but just for the sake of it, I began playing music immediately. The HiFiMan 400i 2020 version, Sivga 007, and Status Audio CB-1 were used. Large orchestral classical, big band jazz, Latin jazz, and other larger orchestral varieties were being used for evaluation. It is always a good idea to listen to large orchestras that have a wide variety of instruments. This gives you a reference point on how an audio component can relay sounds from each instrument. There is a I was immediately struck by the U3's ability to separate various instruments with the proper air or space around their locations, even after the first turn-on. I used to listen to headphones through the likes of the iFi ZenDAC, Soundavo HP-DAC1, and Micca OriGen G2, and they all had different sound signatures. The U3 has made me hear instruments that were previously invisible because of the blend of sound within the various orchestras. Small, quiet instruments such as cymbals, triangles, and others were no longer buried behind the entire orchestra. They were lifted and opened to where you could hear them. All the instruments were open to the performances, whether it was a full symphony orchestra or a smaller, more intimate jazz group. It felt like a veil had been lifted between the music and the listener. The placement of instruments on an imagery stage was so precise that you could see where they were located. It was also excellent. The U3 will let you know if you run a bad recording or a poor stream of music. The budget head amplifier is a great device to determine how good your headphones really are. Warming up/burning-in an audio device is essential because the sound signatures can change over time, and I've long believed that it's essential. When you first listen to the U3 it is very detailed and dynamic, and may sound bright to some. As time went on, the audio character warmed up, yet the sound was still detailed with plenty of dynamics. As an aside, you should leave your Head Amps on all the time as they use negligible power. It's not a good idea to turn off and on audio components constantly, and eventually you will discover that your audio components will have a longer shelf life. Musical instruments have an accurate timbre to their sounds, which is a positive aspect of the U3. I kept asking myself if it was really a thirty-something dollar head amplifier. If ever there was a piece of audio gear that was beyond expectations, the U3 is it. I wondered if the U3 sounded good with the entry level SMSL M 100 or the Schitt Modi 3 DAC's, what would it do with more expensive and higher end units? If the U3 was priced at $100 to $125, I would still call it a bargain. It makes you want to pair it with a better one. I can only imagine that the sound quality would be improved even more. I do a lot of reviews and postings about audio gear. I found this Douk U3 to be stunning, given its ridiculously low price. Pick one up before the price goes up. I'm ordering a second one because I want to change out the opamp in one and keep the stock one. It's a no-brainer at this price. After a series of excellent reviews, the vendor increased the price of the audio items, which were very inexpensive. I believe that Douk will raise the price once he sees the reviews on the U3. The ability to easily remove and change out the Op Amps is addressed. This is something I had initially not considered doing with the U3 but since Douk specifically advertised this feature, I was interested. I bought several Op Amps and tried them all. There were some sound differences that made the U3 sound different. I found that upgraded Burson Op Amps did the best job of elevating the sound performance of the U3. The Burson V5 version had a warmer upper register, but still maintained excellent detail/definition, and had quite a bit of weight to the music. When you switch Op Amps as they warm up, their sound character will change and usually for the better, so keep in mind. When you first install an Op Amp in the U3 it may sound brighter, but don't let that deter you. It is possible to see a change in sound character after a few hours or 48 hours. If you put the op-amp in the wrong way, it will burn out and destroy the unit. Before you do any op-amp rolling, be careful and know what you're doing. The op-amp that comes with the U3 is quite competent. There is a Do you have any negatives you would like to ask? The front blue light which indicates on/off status of the U3 is large and bright when compared to the rest of the unit. It has a bright blue light which can light up a room at night. It can be very distractive when it's on, especially at night, when you're sitting close to it and listening to music. It becomes more pronounced when that light is blue. It would have been nice if Douk had designed the light to be either green or red. That's the only negative thing I can report. I bought a second U3 after I got the first one. There is a Are they good when it comes to support? One of my U3's developed a loud hum in the jack after 4 months. I initially thought it was the headphones I was using, but soon realized it was the U3. I contacted Douk via Amazon. They sent me a new U3 in a matter of minutes. That's support to the max. There is a The Douk Audio U3 mini head amplifier has a 5 star rating because of its low price and high performance ratio. It's that good.
The A07 power amplifier uses the TPA3255D2 chip and the NE5532 op-amp chip. It's easy to set up. It's a nice mini audio amplifier. The Hifi integrated class D amplifier has a max power output of 300 Watt. 3.5mm AUX audio input and 3.5mm audio output interface can be used to connect any powered device. The design is simple and beautiful, it can be matched with your computer/ desktop/ home theatre system. There is a package with a DC 32V 5A Power Adapter for free. If you want to get the maximum power of 300W, you need to buy a power adapter that uses DC 48V and current is over 7A.
👤Aiyima has done a great job of incorporating Texas Instruments' TPA3255 in their amplifier. As the bigger brother to the A03, ancillary features are once again removed, which will keep costs down and also keep electronic pollution out of the air. Even if it is not in use, the audio quality will degrade even if it is not offered on this model. Don't take my word for it. The A07 performed on Audio Science Review. You will understand why Aiyima is one of the most popular brands of TPA325X amplifier at the time being and the most affordable means of rolling up large in the D chip revolution. There is a You can milk more performance with a 48V power supply if you do some research and pick one up now.
👤This amplifier will not provide 300 Watts per channel, so you should know that. It is not unusual for a manufacturer of audio electronics to state specifications that are different from the ratings of the designed and fabricated whole circuit path. The TPA3255 chip has a peak capability of 300 watt for a very short time, but that is under the best circuit design conditions with an ample power supply, heat dissipation, and ideal circuit design. The included power supply will work well for average use. It's rated at 32 volts, 5.0 Amps, equating to 160 watt, which is an obvious indicator that the 600 watt total claimed could never be reached or maintained. There is a At this price point, the Aiyima A07 is quite good, with a clean RMS power of 50-60 watt per channel. The sound is pleasant and uncolored. There is no audible noise coming from the unit. The amplifier gave me plenty of power to amplify my speakers. This amplifier is small at under 2” tall and a 4x6 inch footprint without knob depth and rear connections. I think this amplifier is a winner because of its price, size, and quality sound. If you don't want to use large or expensive equipment, like a pair of in ceiling speakers or a desktop speaker, this is the amplifier for you. The only change that should be made is for the manufacturer to provide accurate specifications. Recommended!
👤I rarely place reviews on Amazon or anywhere else, but this acquisition got me all exited about it. I received a power amplifier a few days ago. I connected it to my regular equipment, which is as follows. Aiyima T5 is a great combo and is used as a CD transport only. The Denon POA 4400A Class A power Amplifiers are compared to the following power Amps. Bob Carver Sunfire Subwoofer is a vintage speaker. The result is amazing, and I can hear the music sound even better as the breaking in period continues, I expect it to improve even more within a few more days. I want to make sure that this little amplifier is broken in just to be fair, the sound that comes from this little amplifier is simply amazing for it's size, all I wanted is to use it with my desk computer audio equipment. I want a set of mono Amps in the future, and I will be placing my findings on the improvements and issues if any, as well as reviews on Amazon as I complete my comparisons.
It can be compatible with a variety of digital devices, such as mp3 mp4 mobile phone computer, which may lead to noise. The Mini Hifi is convenient to carry and can output great sound.

It is possible to output louder sound, but a sharper one, with a 3.5mm AUX input and output. There are various of digital devices that can be compatible with mp3s, mp4s, phones, laptop computers and 3.5mm audio.
👤What you really want to know is, should I buy this? The answer is short and to the point. There is a For the past few years, a FiiO A3 amplifier has been a constant item in my backpack. If you want to get the most out of your headphones or music, you need a headphone amplifier, otherwise you're just listening to a hot mess. A bad headphones amplifier can be just as bad as a bad amplifier. I was a bit nervous when I opened the box. It was a bad sign that it was more generic. The first thing that struck me was its size and weight. The FiiO has a bass boost switch, but this does not. Also, note: The description says it has a bass boost switch, but it is not. Bass boosting on headphones is a gimmick. The construction is all metal and has ports straight and true. Did you think it would be for the price? I instantly noticed how quiet it was when I first plugged it in. You had to turn it all the way up to get a hint of hiss, as a matter of fact. The Sennheisers did the same thing with all of my other Amps. The price is where this amplifier shines. It was less than $25 at the time of this review. The US Dollar. Are you serious? That is less than 12 of my usual daily driver. I have been using this for 9 days now and I have yet to charge it. There is a This little guy is nice and does what it is supposed to do, so it will help drive your headphones. There was just that little bit of additional power. If you are still undecided about buying these, you can jump on down and buy them now. Is this a good idea? Is that what you mean? Yeah! The rating is. Thanks for taking the time to read my review, I hope it helped. Have a great one. Cheers!
👤Another reviewer said to not be misled by the packaging, which said " Enjoy the shock of HD!" The same box is used for many things. The polished, brushed black aluminum case has an abundance of bells and whistles. A red light on the back of the unit shows the power of the charging port and a second red light shows the power of the speaker. They included a signal boost switch. They outdid themselves with their cables, which included an adequate lengthusb power cable, a short TRS cable with 90 degree elbows, and a long TRS straight-ended cable. The two-sided instruction/FAQ sheet is very comprehensive, even with specifications such as 350mW 32 ohm load, 0.0003 percent, Signal to Noise ration less than 120dB, 20-20KHz Frequency response, and 2000mAh 3.7 volt lithium battery. If you're picky about Chinese products, I'll admit that this quote under their Warnings: There is a battery inside the product, do not open it privately, is great. It's funny. The amplifier works great.
Adopt anodizing technology. The display panel is made of glass and has a high quality gold plated input and output jacks. Professional headphones for mixing in the studio. It's perfect for studio recordings because of their high-resolution sound. The soft, circumaural and repalceable velour ear pads are very comfortable. Made in Germany. A practical single-sided cable.
👤These are the DT 770s. Pro's are built to last and will give you a great audio experience that will make you happy at the Thanksgiving dinner. Your guests will think "Hey, what a nice gesture that this person has made" when you talk about it. I respect that. You have gained a great product and a higher respect from your peers. There is a If you are considering these to be your first step away from your run of the mill, you should consider pseudo-high-grade equipment. I recommend them. I'm using the stock tubes with the T2 2X6J9 amplifier. There was a lot of background noise before I received that. The lack of volume it's willing to provide, not to mention its lack of goals and ambitions, is something I am disappointed with. Don't make the mistake I did, buy a better amplifier. They do produce a decent sound. Anything under 30hz is not going to be well represented. I say this because I just read a review that said these frequencies were rattling their brain. I tested it for shigs. It didn't work out well. The review was written by a rampant drug user in the midst of a binge. frequencies are represented in a respectable manner for headphones and are an excellent entry into higher quality headphones. I use them for casual listening. If you're looking for production value on a budget, I suggest you consider a pair of PreSonus Eris 3.5" NF Reference Monitors. Unless you're banned from headphones because of a failed love spell. I've been there before. Just buy them now! If you don't like them, just return them, no matter how many reviews you read, you're going to have to experience them yourself. The beauty of audio is that there is no right or wrong opinion here, it all comes down to your own beautiful biases. If you buy these and return them to your skullcandys, you're clearly masochistic and I urge you to visit a psychiatrist. There is a There is one complaint I would like to make. The bag is generic. Its weak. It was very disappointing. This is coming from a person who loves boxes, containers, and similar items that hold or organize things.
👤There aren't many reviews that cover the differences between the different versions of the product. I have the 80ohm and 250ohm so hopefully this can be helpful to someone. There is a The 80ohm version has a straight cable while the 250ohm version has a coiled cable. The coiled cable of the 250ohm version makes the headphones feel heavier. There is more cable that hangs off your head. It does make a small difference because the headphones are already pretty lightweight. The straight cable is very long so if you were going to use it on the go, it would be a big problem. There are differences in sound. There are subtle differences between the two models I've reviewed. The 80ohm version has slightly more bass than the 250ohm version. When the bass in a song makes you want to dance on your desk, I love it. I get that with the 80ohm version. I kept thinking that the bass was not as important as I wanted it to be. If you are a person who increases the volume of your music until the bass is strong enough, then you should definitely go for the 80ohm version. I know it's more expensive, but you'll be happy to spend the extra money. These headphones need at least a couple of hours of "burn-in" to sound their best. If you don't like the sound of your headphones at first, then you can try playing some pink noise for a couple of hours or even overnight. The effects of burn-in in headphones are a topic that is debated and controversial in the audiophile community. It's the only free method of improving the sound of your headphones before you use them. Why not try it? There is a If you're not interested in good sound, why would you consider these headphones? The biggest improvement in sound quality I've ever seen was when I bought a digital amplifier. These things make a difference. If you get a Fiio, Centrance Slim or something similar, you will not regret it. If you plan on using these on the go, then you should go for the 80ohm. On the matter of communication. The headband pad is one of the best features of those headphones. I was able to cut some NERF darts, cut them in half and put them in a headband where I needed them. The larger surface on my head allowed the headphones to make better contact with it. The headband is made of metal and you can bend it a little, but the extra padding allowed me to make it feel better on my head. The headphones are light. The ear pads can get hot after a while, but over time the effect decreases. There is a I was looking for the perfect closed-back headphones to use at work. They would need to be comfortable to wear for hours at a time. The 80ohms from the Beyerdynamics DT770 Pro are perfect for that. I highly recommend them.
