==Overview==
Ultrasone AG was founded in 1991 with the stated objective to manufacture advanced headphones with an emphasis on the professional audio sector. A feature of many Ultrasone headphones is a proprietary surround-sound simulacrum technology called ''S-Logic''.〔Long, Russ. (Ultrasone PROline 750 Headphones ) in ''ProAudio Review'', July 1, 2005.〕 The process uses decentralized transducer positioning to spread sound over the outer ear in an attempt to mimic sound heard over speakers.〔 Traditional headphones shoot the sound directly into the ear.
Since 1999, Ultrasone AG has been producing headphones that they claim reduce the risk of hearing damage, through the use of more efficient transducers and earcups shielded to reduce electromagnetic radiation, designated as LE/ULE (Low/UltraLow Emission). Ultrasone claims that magnetic fields so close to the head could contribute to "listener fatigue" and might be "a potential health hazard".〔Gatski, John. (Ultrasone PROline Headphones ) in ''ProAudio Review'', September 1, 2004.〕 According to Ultrasone, their headphones reduce magnetic emissions by up to 98 percent compared to other headphones.〔〔
