Professional-grade and magnetically shielded.

Ultrasone PRO 900 Headphones offer you professional sound performance. PRO 900 headphones are the first pair of Ultrasone PRO headphones with the patented S-Logic PLUS technology. This sophisticated technology combines precision dampening with micro-acoustic reinforcement, allowing driver, buffer-board, and spatial parameters to complement one another optimally. So the acoustical design of S-Logic PLUS models and their tonal fine-tuning result in maximum neutral sound impression with more vivid perception of voices and instruments.

Ultrasone ULE Technology & PRO Design
PRO headphones' ULE (Ultra Low Emission) technology, part of the S-Logic Natural Surround System, offers significant benefits for professional users. Most headphone drivers produce low-frequency magnetic fields as they convert an electric signal into the acoustical signal you hear as music. In response, Ultrasone developed a special MU Metal shielding to reduce the radiation by up to 98% compared to current headphones. The ULE technology has stood the test of international review and is recommended by technical surveillance organizations. Ultrasone originally developed the ULE technology for professionals, since they spend much of their lives in headphones. But due to popular demand, the ULE technology has now been integrated in other Ultrasone headphone lines.

Safer Listening
S-Logic doesn't just create a Natural Surround Sound. S-Logic allows at the same time a reduction of sound pressure levels by up to 40% (3-4 dB) for the same perception of volume. This may reduce the risk of hearing damage while ensuring hours of fatigue-free listening.

This are simply the best production headphones ever, I've used noise canceling ones but the S-Logic technology added to the already powerfull pro 900 totally beats them!, you are having almost handmade quality at a minimal price!, I'm speechless... I tested 6 continuous hours and this is the first time I swear that my ears don't hurt...

YOU deserve them, and you ears do as well, you can feel the difference as you hear with the same loudness with zero-clipping, hi fidelity, and the best of all: not hurting your ears..

Hey, if you are like me, and spend hours of hours recording samples and stuff in your home studio, these are Highly recommended, don't waste your money on any other, this are the ones!
