Ultrasone PRO 900 $599 headphones with S-Logic Plus

German audiophile headphone manufacturer Ultrasone has announced the PRO 900, its first headphones with S-Logic Plus technology.  S-Logic apparently reduces sound pressure on the listener's ear drums, as well as improving tonal perception.  The PRO 900's also have 40mm titan-plated drivers, with a 6Hz to 42kHz frequency range.

The headphones weigh 295g without the cord – of which two are supplied, straight and curly – and use MU-Metal shielding to "reduce the amount of radiation directed to the listener by up to 98%, as compared to conventional headphones".  Since I don't think normal headphones use microwaves, say, it's not like your head is being cooked without MU-Metal shielding, but Ultrasone would nonetheless like us to believe that its presence is A Good Thing.

It doesn't come cheap, though.  The Ultrasone PRO 900 headphones are available now, priced at a whopping $599.

S-Logic™ Plus Technology

S-Logic™ Plus is the newest advancement in the S-Logic™ Natural Surround System. By acoustically redesigning the earcups, Ultrasone has squeezed a large soundstage into a more streamlined ear-cup. S-Logic™ Plus profits directly from innovations developed for Ultrasone's flagship Edition range. This sophisticated new technology combines precision dampening with micro-acoustic reinforcement, allowing driver, buffer-board, and spatial parameters to complement one another in an optimal manner. The result is a most neutral sound impression with more vivid perception of voices and instruments.
