Read more… Digital Noise Cancelling blocks out any background noise using the two microphones built into the headphones by working simultaneously, one inside the can and one outside, to shut out any noise that would disrupt your listening experience. Take control of the external noise too: Ambient Sound mode keeps you aware of sounds like traffic for extra safety, while Quick Attention lets you decrease music volume instantly by placing your hand over the housing for easy conversation. High-Resolution Audio Gain greater dynamism from your music collection with support for High-Resolution Audio. Increasing both audio samples per second, and the bit-rate accuracy of each sample, gives great assurance that the music is heard at the same studio quality that was intended by the studio engineer. DSEE HX technology upscales compressed non Hi-Res music files to nearly High Resolution Audio quality too, so whatever you're listening to sounds as good as possible. Transmitting High-Resolution Audio at the maximum transfer rate of 990kbps, LDAC technology gives you a substantial wireless listening experience by supporting your wireless environment. Dynamic Audio Drivers Low frequencies are powerful and weighty in their delivery, whilst high ranges are conveyed with more emphasis and impact, offering a broader range of dynamics thanks to the 40mm High-Resolution compatible HD driver units.
