35dB deep noise cancellation * Allowing you to enjoy a world with less background noise
The earbuds adopt the dual active noise cancellation technology with feedback and feed-forward microphones. They effectively cancel ambient noise and reduce excess noise in the ear canal. Noise cancellation can be as deep as 35dB*.
*Noise cancellation is enabled through active noise cancellation technology. It supports a maximum noise cancellation depth of 35dB, which can reduce background noise by up to 98%. The test data are provided by the National Institute of Metrology, China. Actual results may vary depending on the size of a user's ears, buds selected ear canal structure, how earbuds are worn, whether the user is chewing or exercising, etc.
