Soundcore’s new sleep earbuds promise noise isolation that blocks out “sawing wood or grinding gravel.”

In celebration of World Sleep Day 2024, Anker’s Soundcore has announced a new and improved set of sleep earbuds. The Sleep A20 true wireless earbuds are on their way and come with a slew of improvements over their predecessor (the 2022 Sleep A10 earbuds). The brand promises vastly improved noise isolation, longer battery life and some new features not often found in the best earbuds, such as an alarm and sleep tracking via a companion app.

From the outside, the A20s look similar to the A10s, with an ergonomic, side-sleeper-friendly design. Inside, however, are new patented ‘Twin-Seal’ eartips that Soundcore says are three times more effective at blocking noise than traditional eartips.

While it’s not active noise cancellation, Soundcore says the seal is so effective that it even blocks out the sounds of “sawing wood, chopping wood, or grinding gravel” on the other side of the bed. If your partner does not like night-time jobs, the A20 also causes more typical night-time nuisance, such as snoring or passing traffic.

If you’re worried, as you may be, that such effective noise blocking could cause you to miss your morning alarm, Soundcore has remedied that by adding an alarm function – also beneficial for couples who work on different sleep schedules and who need to wake up phone call that won’t disturb a happily slumbering bedmate.

If you don’t want to sleep in complete silence, the A20s have a built-in library of ambient sounds and white noise which can be accessed while the earbuds are in their battery-efficient ‘sleep mode’. Alternatively, you can connect to Bluetooth to listen to your favorite sleep podcast, audiobook, or Spotify playlist through your phone. Battery life is also improved compared to the first generation earbuds, with up to 14 hours of playtime in sleep mode or up to 10 hours when using Bluetooth.
