Foldable closed-back headphones with 50mm Mylar drivers, enhanced S-LOGIC technology for natural surround sound
Review: The Ultrasone PRO-550 foldable closed-back headphones are professionally designed and equipped headphones. Detachable cables, extra cable, speed-switch earpads including a spare pair of earpads, hardcase for storage and transportation and many more details will meet professionals needs. The 50 mm heavy duty driver produces an imposing sound intensity, with tight and powerful bass plus precise and detailed instrument placement. Combined with all of the useful accessories included in the PRO hardcase, the closed PRO 550 finds its fans within bass players and drummers. Due to requests we implemented an additional function which enables you to fold these headphones easily. The with ULE-technology (Ultra Low Emission) and PRO 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. 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. These headphones also feature S-Logic natural surround sound. Through S-Logic natural surround, the sound moves out of your head and into the room around you. Consequently, the music is no longer confined, but breathing once again, spacious and organic, direction and distance are more easily perceived. It's like being at a live concert. No additional equipment is necessary. So with just a pair of Ultrasones and your favorite audio device, prepare yourself for genuine 3-dimensional enjoyment. Also good for safer hearing, the S-Logic does not only create a natural surround sound, it 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.
