PreSonus HP-4 Headphone Amp

Are you and your session players and bandmates tired of straining to hear underpowered headphones? We were too. That’s why Jim Odom and his jambalaya-fueled team of engineers designed 150 mW headphone amps for the HP4 headphone-distribution system.

These headphone amps are not just loud enough for session and stage use, they’re loud enough to explode the oysters in a Po’ Boy sandwich. Yet the sound is clear and clean, with a wide dynamic range. At last, everybody will be able to hear—assuming they are capable of hearing. Be careful with that level control!
