With the Soundcore Sleep A20, you can enjoy a peaceful sleep experience. These sleep earbuds block sounds like snoring and other white noise, so you hear these sounds less well. That way, you sleep better. You can use the earbuds in Bluetooth mode or sleep mode. In Bluetooth mode, you can listen to your own playlist in Spotify, for example. In sleep mode, you can listen to music and sleep noises you can put on the earbuds yourself. If you sleep with this mode, you have a total 80-hour battery life. This equals 10 nights of sleep. In the Soundcore app, you get an analysis of how you sleep. For example, when you roll over and how long you sleep. This way, the app helps you improve your sleep.
