What is Soundcore Sleep A20 (Sleep Earbuds)?
The Soundcore Sleep A20 are in-ear earbuds designed specifically for use during sleep. They feature a passive sound masking system using double-seal ear tips to reduce ambient noises such as snoring or external sounds. The device does not have active noise cancellation, relying on physical isolation to limit nighttime noise disturbances. These earbuds are equipped with MEMS sensors to track the user's movements and sleep positions. Collected data is synchronized via the dedicated mobile application, which also offers a library of calming sounds. The design is optimized for comfort, especially for side sleepers, through an ergonomic structure and flexible materials.
