Ultrasone PRO 900 Headphone

"There are no surprises awaiting in your mix when you work in these headphones. They give you the truest, most honest sound of any headphones I have ever heard. Some headphones can fool you into thinking something sounds great, and then you hear it through speakers and it sounds totally different. I love the how long the cable is on these headphones. It gives you enough space that you don't feel like you are on a leash. I have yet to experience ear fatigue with the Ultrasone headphones, and I have worked for hours straight in them. Thanks for passing these on for me.”

“I've been using the Ultrasone Pro 900's in my home studio, and I couldn't be happier! They are so sonically superior to any headphones I've used in the past. I've become so spoiled now, that I don't consider my mix complete until I've listened to it on these babies. Sometimes I'll have to record or mix while I'm traveling, and it's great to know that I can really trust what I'm hearing through the Ultrasones and their S-Logic plus system. Their sound is open, natural and true, and I don't have to blast my eardrums to get an accurate level of sound - which is great, especially for late night sessions! They're incredibly comfortable, as well. Hours can fly by before I'll realize that I'm still wearing them. I love the quick change ear-pads, too - way to go guys! It's also been great re-discovering my music collection, hearing things that I'd never heard before. Overall, It's been amazing to explore and experience the aural feast these headphones provide. From recording to mixing to listening, Ultrasone - pure pleasure every step of the way!”

ULTRASONE S-Logic PLUS Technology The PRO 900 offers professional and unlimited sound performance. This is the first pair of Ultrasone PRO headphones with the patented S-Logic PLUS technology. Enjoy the new standard and trust your ears...

S-Logic™ Plus is the newest advancement in the S-LogicTM Natural Surround System. S-Logic™ Plus profits directly from innovations developed for our flagship Edition range, the ultimate headphones for critical listening. 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. 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.

ULE-Technologie & PRO Design PRO headphones stand for Ultra Low Emission (ULE-technology) with significant benefits for professional users and PRO headphones show a specific design. The PRO 900 appearance does not only distinguish the professional line but also allows due to more ear anatomy area a higher degree of transparency in combination with the spatial sense and understanding. The PRO900 headphones offer an additional possibility to choose a black pair of PRO headphones with black and silver velvet earpads.

To understand what ULE-technology does, you need to know that most headphone drivers produce low-frequency magnetic fields as they convert an electric signal into an acoustical signal you hear as music. In response, Ultrasone developed a special MU Metal shielding (ULE-technology) 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 as they do spend half of their lives in headphones. But due to grand requests the ULE-technology has now been integrated in other Ultrasone headphone lines.

Safer hearing S-Logic™ does not only 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 loudness sensation. This may reduce the risk of hearing damage while ensuring hours of fatigue-free listening. However, Ultrasone generally advises not to listen to music at high volumes to prevent hearing damage.
