Comments about Pyle Pro PHA40 4-Channel Stereo Headphone Amplifier:
We're a voice-over studio and it helps to have a clean headphone feed...and this little amp shines. It was a rocky start as the first one arrived with no left channel and a terrible hum. A call to B&H and a replacement arrived quickly. The second one is low-noise, has plenty of power, and the price is right.

Comments about Pyle Pro PHA40 4-Channel Stereo Headphone Amplifier:
Wanted a small amp for my computer speakers, this one works great, is compact on my desk. The only bad side is I had to find 4 1/4 to 3.5 adapters so I could plug in earphone jacks. It would be great if they were offered with the amp. Up charge for this would be no problem.
If you want to give your comnputer speakers some extra volume then this will work for you.

I use this for my home studio and i can't believe how my monitor mix sounds so accurate.I ordered two,one for the mix room and the other for the drum room. Very compact item to store away and carry less equipment around. I don't really have any negative reviews on this item.

Comments about Pyle Pro PHA40 4-Channel Stereo Headphone Amplifier:
Now I can finally use my 4 different monitoring systems in my home studio thanks to this little thing.
There is no volume inconsistency or anything else. Takes a stereo input and gives out the same amount of signal through all four outputs.
