Perfect! - Reviews PreSonus HP-4

I have recently and used with a Beyerdynamics DT770 headphones and a Presonus Audiobox USB sound card and I am fully satisfied.
It has the features you would expect on a device of this type (Button / mono monitor mute), potentiometers are of good quality and enjoyable. The output level is quite high (although my headphone makes 250 Ohms I never exceeds half the level).
I really felt a big difference from the first use, a huge gain in the low frequencies (low I found on my headphone) and a dynamic boosted.
For the price it is definitely a bargain!
