Designed for musicians and performers who demand mobility without compromising audio quality, the HP2 personal headphone amplifier is a great choice for driving wired in-ear monitors (IEMs), as well as headphones. PreSonus HP-series headphone amplifiers have long been popular for their loud, clean, clear sound and roadworthy built quality. The new HP2 delivers these qualities in an easily affordable, stereo device so you’ll hear every note and beat clearly wherever your music takes you.
