According to reports, the headset supports 35dB active noise reduction, built-in a variety of sleep-aiding audio, and adopts a design that does not protrude from the ears, so it can be worn even when sleeping on the side.

The Soundcore Sleep A10 can also monitor the user’s sleep and provide sleep quality reports in the companion app. When the user needs to wake up, the headset can also gently wake up the user through the alarm clock function.

Anker claims that the Soundcore Sleep A10 can get up to 10 hours of playback time on a single charge, and the charging case provides an additional 40 hours of playback time for $179.99 (about 1283 yuan).
