Product description Featuring patented S-Logic Plus technology, the PRO 900i Closed-Back Professional Reference Headphones by Ultrasone are geared toward audio professionals who demand precise reference monitoring, whether in the studio or on location. The stiff and strong 40mm titanium-plated drivers provide high-fidelity sound throughout the audio spectrum, and are light enough to ensure ultra-fast response time and accurate sound reproduction. The velvet earpads form a seal around the ears that prevents the sound from leaking out, and that sonically isolates the listener from their surroundings. The S-Logic Plus technology is at the core of the listening experience offered by these headphones. It delivers a spacious and natural 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. - Pro-Quality Sound
- 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.
- Safer Listening
- 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.
- Detachable Cables
- Two detachable cables are included: One short 4.9' ultra-soft straight cable (USC) with a gold-plated 3.5mm jack for lightweight mobility, and one long 9.8' coiled cable with Neutrik 1/4" jack that provides reach and prevent snags from pulling headphones off your head.
