Overview

More power and less strain.

Ultrasone PRO 550i closed headphones produce a clear sound combined with impressive intensity and strength. The PRO 550i have a foldable design with aluminum nameplates. Includes PRO Box (hardcase) for safe transportation and storage, including accessories. Technologies: S-Logic Natural Surround Sound, MU Metal shielding (ULE-technology), safer hearing.

Character
The PRO 550i are professionally designed and equipped headphones. Detachable cables, extra cable, speed-switch earpads, a spare pair of earpads, hardcase for storage and transportation, and many more details meet professionals´ needs. The 50mm heavy-duty driver produces an imposing sound intensity. Tight and powerful bass plus precise and detailed instrument placement are delivered. Combined with all useful accessories included in the PRO hardcase, the closed PRO 550i finds fans among bass players and drummers. Due to requests, Ultrasone implemented an additional function which enables you to fold these headphones easily.

S-Logic Natural Surround Sound
Through the S-Logic Natural Surround Sound the usual headphone sound will be moved out of the head into 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 in a live concert. For this new technology, additional equipment is not required. Take a pair of Ultrasone headphones plus your sound device and you will be ready for the 3-dimensional sound enjoyment.

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.
