[Triple noise cancellation] Hybrid ANC + 1 engine. Thanks to the active noise reduction of digital blending technology, the environment automatically ADAPTS, blocking 96 percent of the annoying noises and giving them a better sound score. Built-in six microphones improve the clarity of the call so you can listen clearly and focus on the call. [First-class sound quality] Dynamic 40mm driver, low distortion, state-of-the-art ZrO2 coated polymer film, high resolution. With codecs and the latest CSR Bluetooth 5.0, the nuances of each sound become more detailed. [3D touch operation] intuitive and simple! Volume, play, stop, pause, and title changes can be controlled via a trackpad on the right earmuff. Just swipe up and down, left and right. A beep indicates that an operation has occurred. [Zero Pressure Ear Mask Design] Large and deep earcups completely close the ears, with breathable memory foam earpads, so you won't feel any pressure on your ears. This makes them super comfortable to wear, even for longer periods of time. [Pause and Auto Play] The built-in infrared proximity sensor automatically stops audio when the headset is removed, and then resumes when the headset is put back on.
