The HD9/HP4 bundle from PreSonus consists of a powerful HP4 headphone amplifier with 150 mW per channel and four professional HD9 monitoring headphones in a closed, comfortable design for studio recordings and live applications. The latter offer a very wide, transparent sound for accurate mixing despite the sound isolation, while the amp provides crystal clear amplification without compromise.
A good and loud headphone sound is essential for successful recording sessions. The HP4 delivers a whopping 150 mW per channel and delivers extremely low-noise, undistorted sound for up to four separately adjustable headphones.
If you are looking for closed and comfortable headphones, the HD9 from PreSonus is the best choice for you, as it sits comfortably even during longer sessions and isolates the sound both on the outside and on the inside. Perfect also for those who work in a concentrated way, but at the same time have to take other people into consideration. Despite the isolation, the HD 9 offers a very wide, transparent sound for accurate mixing. Thanks to high-quality 45mm neodymium drivers and the high power handling (900mW per channel, 40 Ohm) a loud, clear and clean audio sound is guaranteed at all times - in the range from 10 Hz up to 26 kHz! The simple and elegant design convinces of course not only with the Look adjustable headband, but also with the 180° rotatable and foldable shells and the comfortable, durable ear pads.
