Product Overview & Key Features
Adaptive Active Noise Cancellation
The fully-upgraded noise cancelling system targets and blocks out a wider range of noises, reducing up to 98% of ambient sound. Adaptive noise cancelling automatically selects a suitable level based on your location (indoors, outdoors, commuting, or flight). Users can also choose from 5 noise cancelling levels via the Soundcore app.
