The PRO 2900i Open-Back Professional Headphones by Ultrasone provide precise reference monitoring demanded by audio-professionals who prefer open-back headphones, whether in the studio or on the road. Open-back headphones are designed to allow some outside noise to mix with the headphones' acoustic, and are an appropriate choice for listeners who prefer an open and natural sound (think listening to speakers in a room). They may also feel more comfortable because of lighter pressure on the ear area.
The S-Logic Plus technology is at the core of the listening experience offered by these headphones. It delivers a spacious and accurate sound with a wide frequency range, and it generates lower sound pressure level than traditional headphones while achieving the same perceived loudness. This can potentially reduce hearing damage and facilitate fatigue-free listening. Incorporating components developed for Ultrasone's flagship Edition series, the acoustically redesigned earcups and their tonal fine-tuning aim to achieve a sound free of coloration, ideal for monitoring, engineering and mastering.
Other features include ULE technology, which utilizes MU-Metal shielding to protect listeners from the potential effects of low-frequency radiation generated by headphone drivers. The headphones come with two detachable cables, one straight and one coiled. A hard-shell transport case and a second pair of earpads are also included.
Designed with audio professionals in mind, the 40mm titanium-plated drivers provide precise sound reproduction ideal for monitoring reference. In addition, S-Logic Plus technology delivers a spacious and natural sound with a wide frequency range of 6 Hz to 42 kHz, and authentic rendition of voices and instruments.
S-Logic Plus technology utilizes a decentralized driver to send music around the ear, not just into it. The sound is projected onto the surface of the outer ear rather than the inner ear directly, providing the same loudness sensation as other headphones but with a reduction of sound pressure level by up to 40% (3-4 dB). This may reduce the risk of hearing damage and contributes to fatigue-free listening. The earcups' MU-Metal shielding reduces electromagnetic fields by up to 98%, protecting listeners from the potentially harmful effects of low-frequency radiation generated by headphone drivers.
Two detachable cables are included: One short 4.9' ultra-soft straight cable (USC) with a 3.5mm jack for lightweight mobility, and one long 9.8' coiled cable with Neutrik 1/4" jack that provides reach and prevents snags from pulling headphones off your head.
