Anker Soundcore Sleep A20 vs Ozlo Sleepbuds 2
Which should you buy? Our verdict on both, pulled from our full The Best Sleep Headphones: 4 Compared (and One to Skip) comparison.
The Soundcore Sleep A20 is the do-everything sleepbud for most people, balancing side-sleep comfort, all-night battery and a genuinely useful app at a mid-range price. Step up to the Ozlo Sleepbuds 2 if masking a snorer or street noise is your top priority and you want the smallest bud here.
Anker Soundcore Sleep A20
Buy itThe sleepbud that finally nails the whole package: flat enough to lie on, a genuinely full-night battery, and an app that does white noise, sleep tracking and alarms.
- Low-profile twin-seal fit that reviewers say stays comfortable for side-sleepers
- Rated 14 hours in sleep mode on a charge, and 80 hours in total with the case
- App bundles a customizable white-noise library, sleep monitoring from a motion sensor, and alarms
- Passive isolation only — it masks noise rather than actively cancelling it, so a loud snorer can still bleed through
- Tiny buds are easy to misplace in the sheets if you skip the case
Ozlo Sleepbuds 2
Buy itThe smallest bud here, with noise masking that switches on by itself when you fall asleep, for anyone whose enemy is a snorer or a noisy street.
- At 1.6 g and 11 mm tall per bud, Ozlo's figures make it the smallest and lightest sleepbud in this comparison
- Rated up to 14 hours of playback, and it shifts from streaming to adaptive noise masking when it detects you have fallen asleep
- Streams Spotify, Calm, Audible and any Bluetooth source, with 60+ sleep sounds, an in-ear alarm, and sleep and room tracking via the buds and Smart Case
- Premium price for what is still a single-purpose sleep device
- Noise reduction is passive, through the silicone tips, with masking on top; Ozlo states it is not ANC
- A 1-year warranty, and the phone needs to stay within 30 ft and the case within 10 ft
