HA400 : Behringer HA400

I use this headphone preamp to make the music coming from my cellphone louder when I play the drums to music.

For his use the HA 400 works great.

I haven´t tried yet how it works with 4 Headphones. I just use it with one.

handing:

Is very good. There are just 4 simple knobs: The level for each output.

In addition it´s very small, but for this size it´s quite heavy, wich is great because every time I want to plug in or remove a cable I don´t have to hold the HA 400.

Features:

There are just 4 smple knobs: The level for each output.

I would have liked an ON/OFF control.

Sound:

the sound stays very good. Maybe there is a little bass boost. But i did´t measured it

Quality:

2 of the 4 level-knobs grate a little bit, but the rest is very good.

I hope I Could´ve helped you
