Cheap design, works only for limited applications
The internal circuitry is rather cheap. Instead of dedicated amplifiers it uses a cheap and old op-amp amplifier circuit. It works, but can't provide too much output power. It would have high distortion with low-impedance headphones. Worse yet, it doesn't have any internal power regulation and completely depends on the power supply for that. This means that switching power supplies would have unacceptably high noise and this circuit is only usable with transformer-based power supplies. The PCB is secured by only two screws, which means it can bend quite significantly when jacks are inserted or removed. This could cause circuit failures.

BAD PRODUCT
Once headphones are plugged all the way in signal goes mono. If you want you can find the sweet spot that pops and cracks in stereo when user moves ever so slighty. Additionally, I have no idea why the input and outputs are on the same side of the equipment. Shabby design. I highly recommend investing an extra 20 or more dollars on something that works than complete wasting your money on this Pyle Pro. Over the years it has become quite apparent Pyle does not give a hoot about their product and certainly not their customers.

Excellant Headphone Amp
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.

Great product, especially for the price
I work in theater and often need to do recording sessions with a number of people who want to be able to listen at the same time (me, a director, a couple performers). For under $, the PHA40 is an ideal way to solve that need. It is very simple to use, allows everyone to control their own volume, and basically just works as advertised, which is something to be skeptical about for this price. I do wish it came with a few 1/4 to 1/8 adapters, but those are fairly cheap on there own if you need them.

Great deal for the price
Does everything you would expect from a cheap headphone amp and more. Very satisfied. I use it to boost the signal from an Ipod.

GREAT AMPLIFIER
THE BEST YOU COULD BUY FOR THE PRICE AND AMPLIFICATION LEVEL. THE ADDITION OF A POWER SWITCH WOULD MAKE IT PERFECT

Meh
This is a good product if you use a stereo input, have plenty of signal to send to the amplifier, and don't care that it is a bit of a counter-intuitive design. I don't have much signal that I can send to the amplifier, and it is incredibly quiet. Great for a silent studio, not great when you are playing a show and need a cheap wired in-ear. For the money, ehh, i'd go up a couple notches. Good for the wallet, nightmare for the sound guy.
