Soundcore Sleep A20 | Noise Blocking Sleep Earbuds for Side Sleepers
Soundcore by Anker
Overview
The Soundcore Sleep A20 earbuds are purpose-built for one thing: helping you sleep better. Unlike regular earbuds crammed with features you won't use at 2 AM, these focus on what matters—comfort, passive noise blocking, and genuinely soothing audio. The ultra-slim 3mm profile and ergonomic design make them disappear when you're lying on your side, a revelation for side sleepers who've tried everything. The twin-seal ear tips (7 sizes included) provide 30dB passive noise reduction in high frequencies—enough to soften snoring, traffic, and HVAC hum without the artificial pressure of ANC. Battery life is exceptional: 14 hours in Sleep Mode (playing local sounds) or 10 hours streaming via Bluetooth 5.3, totaling 80 hours with the case. The Soundcore app offers 48 customizable sleep sounds you can mix and match, download to the earbuds, and play phone-free. Sleep tracking via MEMS sensors monitors position and duration, though accuracy is inconsistent. There's no ANC here—that's intentional. For under $150, the A20 delivers comfort-first sleep audio that doesn't try to be everything. It's the budget king of sleep earbuds.

Frequently Asked Questions
Do Soundcore Sleep A20 have Active Noise Cancellation?
No—and that's intentional. The A20 uses passive noise isolation via twin-seal ear tips, providing 30dB reduction in high frequencies. This approach avoids the "ear pressure" feeling some people experience with ANC during extended wear. If you specifically need ANC for sleep, consider the Soundcore Sleep A30 instead.
Can I use Soundcore Sleep A20 for side sleeping?
Absolutely—this is their primary design goal. The 3mm ultra-slim profile and ergonomic shape allow them to sit flush in your ear canal without protruding. Most side sleepers report they can comfortably sleep on them all night, even with firmer pillows. The 7 included ear tip sizes help ensure a pressure-free fit.
How does phone-free Sleep Mode work?
You can download up to 3 custom soundscapes (mixed from 48 sounds in the app) directly to the earbuds. Once downloaded, you can leave your phone off, in another room, or on airplane mode. The earbuds play from internal storage, extending battery to 14 hours and eliminating late-night phone temptation.
Are Soundcore Sleep A20 good for blocking snoring?
They're effective for moderate snoring (up to 55dB) when combined with masking sounds like brown noise or the app's "snore mask" presets. Severe snoring (65dB+) is harder to fully mask without uncomfortably high volume. They're a good first step before considering ANC models like the A30.
