Key product features

Adaptive Active Noise Cancellation (ANC) reduces the perception of ambient sounds and adapts to the surrounding conditions. This allows you to stay more focused on listening in different sound environments. A built-in microphone allows you to use the headphones for phone calls.

Head-tracking surround sound changes the perception of sound direction based on head movement. With supported audio content, the sound appears spatially positioned rather than just perceived as a conventional stereo signal.

The model is listed as offering up to 53 hours of battery life, while the key battery specs give a range of 10 to 15 hours. IP55 water resistance defines the housing's protection against dust and water; the label therefore specifies the level of protection, not the way the headphones work.
