Foldable, closed-back professional headphones with S-Logic for amazingly 3-dimensional listening. MU Metal shielding cuts down on low-frequency magnetic radiation. Design allows for excellent fidelity at lower volumes for increased hearing protection.

PROline stands for Ultra Low Emission, providing numerous features for professional users. The professional line are designed to work with your ears' anatomy to achieve a higher degree of transparency and spatial perception.

PROline technology was systematically developed for professionals that spend substantial time wearing headphones. Most headphone drivers today convert an electric signal into an acoustical signal, producing low-frequency magnetic fields. Medical research shows that these emissions can be hazardous to our health. In response, ULTRASONE developed a special MU Metal shielding to reduce the radiation by up to 98% compared to current headphones. The patented PROline (ULE=Ultra Low Emission) technology has stood the test of international review and is recommended by technical surveillance organizations.

S-Logic Natural Surround Sound
Through the S-Logic Natural Surround Sound the usual headphone sound will be moved out of the head in the room around you. The sound is no longer locked in, but appears broad and detached. Directions and distances can be heard and perceived - it's just like being at a live concert, with real 3-dimensional sound enjoyment!

Safer hearing
S-Logic Natural Surround Sound allows an up to 40% lower dB output (3-4 dB) for the same loudness perception. This may significantly reduce the risk of hearing damage while ensuring hours of fatigue-free listening - an absolute must if you spend a lot of time in headphones.

These closed-back headphones offer excellent external noise suppression and use the stiffest titanium-plated drivers available. These drivers offer the most exact and correct sound reproduction you can imagine. The velvet ear pads give fantastic listening comfort for many hours, combined with maximum isolation. The headphones are foldable for compact storage and easy transportation in a suitcase.

from North Knoxville/Ftn City

I had the pleasure of using these phones in audio engineering school @SAE in Nashville. They blew me away. Unbelievable sound clarity, full bass and mids and you can listen for hours on end without straining your ears. These are far and away the best set of cans I have ever used.
