The technology that makes it happen Dual noise sensor technology, featuring two microphones on each earcup, captures ambient noise and passes the data to the HD Noise-Canceling Processor QN1. Using a new algorithm, the HD Noise-Canceling Processor QN1 then applies noise-canceling processing in real time to a range of acoustic environments. Working together with a new Bluetooth Audio SoC (System on Chip), it senses and adjusts to music and noise signals, as well as acoustic characteristics between the driver unit and ears, at over 700 times per second.
