Signature STUDIO are titanium-coated 40-millimetre Mylar sound transducers. These drivers provide a frequency range of 8 to 40000 Hz – a far broader range than that of human hearing. The titanium coating, one of the hardest materials in the world, guarantees high-resolution and precise reproduction of the audio signal. Patented ULTRASONE S-Logic® Plus technology brings two essential benefits to the headphones: One is the wide stereo panorama which, combined with excellent depth gradation, gives the user the impression that they are listening through high-quality studio monitors rather than a pair of headphones. Thanks to S-Logic®, 3 to 4 dB less sound pressure is required to achieve the same perceived volume. This allows you to enjoy long hours of listening without signs of fatigue while at the same time protecting your hearing.
