Simply quickly touch the touch pad twice (right side). TalkThrough – this allows you to easily communicate with others without removing the headphones, even with NoiseGuard™ noise cancellation turned on.
Touch controls – turning up the volume or skipping to the next song can be done using simple intuitive gestures (such as “tap” and “swipe”) on the Touch Pad (located on the right ear cup). That means less engine rumbling on a flight, and more music you want to hear. When switched to “adaptive” mode, the level of noise cancellation will automatically be adjusted to suit the volume of the surrounding ambient noise. All of this without noticeable deterioration to the quality of the sound. World-class noise cancelling – Sennheiser’s unique NoiseGard™ hybrid adaptive noise cancellation combines 2 different systems - using 2 microphones on the outside of the headset plus 2 microphones inside, to eliminate unwanted background sounds over a wide range of frequencies. Flying across the globe on one charge is no small feat. 30 hours on 1 charge – this is probably the key feature for any serious traveller.
