This bundle includes the HP4 4-channel headphone amplifier and the HD9 professional monitoring headphones from PreSonus.

HP4 Tired of straining to hear the headphones? The HP4's four 130 mW headphone outputs are clear, clean, and screaming loud, all packed in a compact, 1/3U chassis. Features include balanced L/R line inputs and outputs, global mute, overall level control, and sum to mono. The line outputs can feed another HP4 or an HP60.

HD9 When you need to do serious work without bothering anyone in your living space and without being distracted by outside sound, choose PreSonus HD9 headphones. They're clean-sounding, extra-comfortable, and offer a broad, transparent frequency response that ensures accurate mixing. The HD9's closed-back acoustic design provides superior listening isolation and reduces headphone bleed, so you hear nothing but music and your housemates hear nothing at all.
