Presonus HP4 Discrete 4-Channel Headphone Amp

The PreSonus HP4Headphone Amp features 4 headphone outputs on the front panel, each with its own volume, and 150mW of amplification per channel—extremely loud output with a low -98dB noise floor. It also allows control over monitors with a separate volume knob that can be muted using the Monitor Mute button. It accepts balanced/unbalanced inputs and outputs (1/4" TRS) and is sized at 1/3 rackspace. Input can either be set to stereo or mono (the mono selector button on the front channel simply copies both inputs to both sides). Powered by an external wall-mounted supply.

The K99 headphones are semi-open and offer you excellent stereo sound at an optimum price. Self-adjusting headband, and low weight ensure pleasant fit. Large, high-performance 1.6-inch (40-mm) speakers provide natural, uncolored sound.

AKG K99 headphones are perfect for your listening enjoyment. They include comfortable leatherette earpads that allow comfortable extended wear. You get a very accurate listening experience, thanks to an 18Hz-22kHz frequency range. AKG makes great headphones for a variety of applications, from studio monitoring to home listening. If you want to plug into a computer, CD player, or MP3 player and experience great sound, then these headphones are perfect for you.
