HUAWEI FreeBuds 4 Earphones

HUAWEI FreeBuds 4 takes Open-fit Active Noise Cancellation to new heights, incorporating all-new adaptive ear-matching technology for even greater audio immersion. The open-fit design allows air pressure to stay equalised, while ensuring important environmental sounds can still be heard — for a safer, more comfortable wearing experience even after long hours of use. *The closer the fit of the earbuds, the greater the noise cancellation effect. Smaller ear cavities allow the earbuds to achieve a greater noise cancellation effect than larger ear cavities. It is recommended to maintain a close fit when wearing the earbuds to maximize the noise cancellation effect.
