Does the job well for the money
mpel 18.03.2020
Well-built package, stable volume control, standard +12VDC power supply (500mA) with a pretty common coaxial (5.5mm OD, 2.1mm ID, 10mm depth, likely IEC 60130-10 Type A; 2.5mm ID seems to fit too) barrel connector, and although the sound isn't comparable with the best, it's not terrible either. With my 62 ohm AKG K-701 I still use only lower volume levels, so the saturation at high volume isn't concerning me too much, and the sound is clear enough (better than most PCs/laptops I tried).

Even after a year of use I wouldn't change much about it, for home use it's definitely worth the money! My only caveats are with the potentiometers:
- the handles could use some rougher edges, so your fingers can grip them easier
- the more you use them the smoother they become; it's a good idea to use all ports to wear the inside of the potentiometers equally
After a year of 3-4 times/week use, the play in them is minimal (sub-1mm) and when used across the range (I turn them down when unplugging) they still feel quite precise.

Tip: if you want to use the 6.3 mm jack input, make sure you have a stereo cable - most 6.3 mm cables on the market are mono only (for connecting guitars to their amplifiers), so you will only hear one channel.

Stopped working after ~1 month of use
MjoreDjent 07.01.2023
The device completely neutered the sound quality coming from my Axe Fx FM9. I bought this device so I could jam with some friends at bedroom sound levels in my apartment when we didnt have access to a studio setup and it just totally conked out after what can only be described as light/moderate use. It also had a tendency to send a loud buzzing noise through my headphones which at one point had me tearing them off to avoid hearing damage.

I tested and double tested everything in the audio chain and the only defect I could find was with this headphones amplifier.

Headphone amplifier

I bought this headphone amplifier for live recording, the features on it are ok but the output is extremely weak.

Excellent product
MikeBass 06.11.2021
Using a USB interface with one headphone socket meant it was awkward to work with other people in the room - this little box was just the thing we needed and everyone can set their own level
