  • No wonder its cheap

    As reviewed by Sebastien on 11/26/2014

    That's cause it's so bad. I received mine and couldn't hear in stereo. Ok, defective unit, it happens. Sent it back, got a new one two months later (yes, two months later!!) and now have to fiddle with the cable to get a signal, and for it to be stereo. Really poor quality, this thing.

  • Very Nice Amp

    As reviewed by Richard on 10/22/2014

    This is my first experience with a headphone amplifier and I was very pleased with the sound quality. The sliders are silent and smooth. The only reason I gave this unit 4 stars is because it should have been built with a power switch, I'm not a fan of leaving small electronic devices such as this on 24/7.

  • Great for the price

    As reviewed by Tom on 7/6/2015

    I bought one this weekend and it works great! It was exactly what I was needing and it didn't cost an arm and a leg, the only downfall would probably be that you only have 1 stereo 1/4 input but in reality that is all I needed. I just run a stereo cable out of my headphone send on my mixer and it adds just enough gain to my in-ears that I am able to hear my mix.....if you are going to use aux sends you will probably have to by a split cable but running out of the headphone Aux worked just fine.....As for the guy that could only hear one side of his headphones? It is probably because you didn't have it hooked up right I am a drummer so if its loud enough for me I am sure it will work for any application
