Soundcore Sleep A20 by Anker Sleep Earbuds

Quiet nights start here

Soundcore Sleep A20 by Anker is a compact sleep earbud system designed for restful nights without harsh disturbances. It blends a distinctive 4-point noise masking approach with twin-seal ear tips that work together to deliver 3x stronger passive noise blocking, especially against high-frequency sounds. While not featuring active noise cancellation, you still get a calmer listening environment enabling gentle, non-disruptive background sound masking.

Designed for side sleepers

The A20 uses an ultra-soft 3D ergonomic design and Air Wing shaping to sit comfortably even when you lie on your side, reducing pressure points so you can drift off with less friction.

Long-lasting power for all-night use

In Sleep mode, expect about 14 hours of continuous use per charge, with the case extending total playtime to around 80 hours. In Bluetooth mode, you can enjoy roughly 10 hours of listening, with about 55 additional hours available from the charging case.
