Ultrasone - Safer Hearing
S-Logic? does not only create a Natural Surround Sound sensation.

S-Logic? allows at the same time a reduction of sound pressure levels at the eardrum by up to 40% (3 - 4 dB). 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.
