It does the job.
nono1989, 27.02.2019
I use it with headphones and with my E-Drums and it works great. It enhances the signal significantly even a little bit too much. It meets my expectations. Besides it has a robust casing and four adjustable headphone outputs. A little con is a lack of on/off switch.

Great for Team Projects
Stravers30, 08.01.2019
This HPA 4 is an inexpensive, robust and simple to use amplifier/singal splitter perfect for multi use production and band practise. I have been using it with my focusrite at my home studio and also at practise with the band straight from our mixing table, now four of us can use headphones at the same time and simultaneously listen to each other , adds a great dynamic to our practises . If you are using this to produce/master music , keep an eye on your volume levels on your DAW as it does boost the loudness signifcantly. a very handy tool.

Low cost Headphone amplifier
JL Cook, 22.04.2020
Housing made of metal, the knobs and the jack sockets don't look really solidly assembled, the output is often noisy.
It requires power and comes with its power supply.
It does its job, it takes a stereo signal and distributes it on 4 separate stereo headphones out. The mono switch on the back is a helpful plus, it can be useful when tracking some live musicians that leave one ear free from the headphones.

Does what its supposed to.
Serano, 09.04.2020
If you are looking for a way to split 1 output into 4, this is the tool. If you are looking for an amplification device, I would advise against this device.

Once you go past the halfway mark of the controls, noise starts to be present in the sound. Also there is no value indication. I believe the device to be at 100% volume with the control half way but there is no certainty.
