This thing is smaller than i expected, but it works as described. Doesn't have too much hiss and i don't hear any static or hum. The high/low gain switch is a major fix if you have headphones that require a lot of power to move large heavy drivers. I have a pair of headphones with 70mm drivers and when plugged into my piano or my laptop they are way too quiet. With this amp on high, they get LOUD. It seems well made and setup was very simple. If there was one thing i'd like to see, it would be a way to mount it to a desk or a wall. the only problem i have with it is that where i use it, it flops around and i had to tape it to my desk. Any type of clip or mount would have been nice to have but i'm just being picky.

THIS PRODUCT WORKS REMARKABLY WELL. I HAVE LOOKED FOR PORTABLE AMPLIFICATION METHOD FOR MY SANSA MP3 PLAYER, AS ALL PODCASTS, MUSIC, ETC. ARE AT A DIMINISHED VOLUME BECAUSE OF UN REGULATIONS. THIS AMPLIFIES JUST FINE. THE ONLY IMPROVEMENT WOULD BE A CLIP SO THAT YOU DON'T HAVE TO PUT IT IN A POCKET (KEEPS FALLING OUT). THE AUDIO QUALITY IS SUPERB, AND THE BUILD SEEMS STRONG, PRODUCT IS HEAVY IN WEIGHT, WHICH I LIKE. RATHER THAN 80% PLASTIC COMPONENTS, I BELIEVE WE HAVE A 80% METAL PRODUCT HERE. BRAVO!

Still not quite loud enough for me on some TV programs. Battery will last 4 or 5 hours a day for 4 or 5 days !

This is my third attempt at buying an amp for my headphones. The first two brands were junk.This one is of high quality, durable, and there is no distortion in the output when set to high gain.This time I also used industrial two sided tape to adhere it to the back of my laptop. The sound output is excellent, and I can now hear my music files on my laptop far better than before.If this one dies, I would still buy the exact same one because of the sound quality and product construction is far better than other brands.

This worked a month or so. Very flimsy inside.

Well I did not expect much from this headphone amp, but makes a big difference in sound quality. I tried it on several audio devices with my oneodio headphones and can clearly hear more details in the music and one of my devices a louran digital music player which has a low volume output now is able to be played at an appropriate volume. During use it's hard to stop listening because of the improved sound quality

I rarely write reviews unless the product is sound and as advertised. This time, it is a pleasure to give this product all the accolades I can.I watch movies in bed, and the sound on my iPad is inadequate. The sound is way too soft and almost inaudible. This product fixes that problem.As you know, I make videos, and again, the sound from my PC when editing was becoming very difficult to hear, and this product fixes the problem.I cannot address longevity since it came in just yesterday, but other than that, it is as advertised and incredible.I highly recommend this product.

Self powered with USB charge port, takes a few hours to fully charge, although would like to have a row of LED's to show state of charge. Great sound fidelity and boost.

My monitoring headphones were not outputting sufficient sound output levels with my portable DAW setup and then I found this unique item on Amazon.This compact audio device (about 3/8" thick and the size of a credit card), provides +6dB of signal gain and even has a variable volume control knob.It is powered with an internal battery which is rechargeable via USB and easily provides several hours of continuous use when fully charged.Made of lightweight aluminum for portability along with a matte black anodized finish with silk-screened graphics, it looks really sharp, professional!This device also serves with my laptop gaming and music systems, when additional volume boost is required.It does the job and is recommended!

Works as expected, volume amplification is not large, not much difference between hi/low modes, sound quality ok, no noticeable distortion, rechargeable battery good after one monthรขโฌโขs use. Overall, good for the price

The built quality is good, charging time is short, this amp reduce the excess of volume that create distortion from low output devices , i use it also with a wd media ,before i could not get sound from the output to my headphones, works great from button headphone to large jbl or klipsh or bo .
