The verdict
The Anker Soundcore Sleep A20 earbuds are comfortable and stay in place for side sleepers, and have a long battery life. Still, they are held back by mediocre sound quality and a lack of ANC.
✓Liked: Comfortable, Multiple ear tip and wing sizes to stay secure, Excellent battery life, Comprehensive app
✕Could be better: No active noise cancellation, Unimpressive sleep-sound presets
