Smart Volume

In Sleep mode, your phone’s microphone detects changes in ambient noise. When there’s a persistent increase or decrease in noise levels, the audio volume adjusts automatically, providing a noise-masking effect that adapts to your environment.

Controls

• Please note that you need to tap with a bit of force for the earbuds to recognize the command.
• You can customize more controls in the Soundcore app. When using dual earbuds, if you modify UI, it will also be effective when using a single earbud. Vice versa.

Power Off

To power off, place the earbuds in the charging case by aligning the charging contacts of both the earbuds and the charging case, and then close the lid. Once the corresponding earbud is back into the case, the first (left earbud) or the third LED indicator (right earbud) will stay on for three seconds and then go off.

Place the earbuds in the charging case and leave the case open. Press and hold the button on the charging case for 10 seconds until the LED indicators rapidly flash white 3 times.

FAQs

Q: What are Sleep A20 earbuds, and who are they for?

The Sleep A20 are true wireless earbuds with a sleep focus that are mainly intended for usage before bed. They cater to those who wish to track their sleep, listen to white noise or calming sounds, or block out noise (such as snoring, city noises, roommates, or family) without using heavy headphones or over-ear devices.

Q: Do they have active noise cancelling (ANC)?

No, active noise cancellation is not used by the Sleep A20. Rather, they rely on a passive “noise-masking” design with unique ear tips (known as Twin-Seal ear tips) designed to enhance comfort by passively blocking some background noise.

Q: Are they comfortable to wear while sleeping — even for side sleepers?

Yes, the A20S’s low profile, soft materials, and 3D ergonomic shape prevent them from pressing against your ear or becoming uncomfortable when you’re resting on your side. Because of this, they are far more appropriate for use overnight than regular earphones.

Q: What kind of sounds can they play to help me sleep?

They come with an integrated library of sounds that are conducive to sleep, like as ambient noises, rain, and white noise, which can be accessed via the companion app. If you like music, audiobooks, or other audio, you may also use Bluetooth to stream your own content.

Q: What if I want to stream music or podcasts instead of sleep sounds — is that possible?

Yes, the Sleep A20 work similarly to standard wireless earbuds in Bluetooth mode, allowing you to stream music from your phone or other device.

Q: Can I set an alarm through them?

Yes, you can use the app to set an alarm that will use the earbuds to wake you up. In this manner, you can use your sleep soundtrack without bothering other people.

Q: Are the Sleep A20 suitable for daily listening (music, podcasts) or calls?

They don’t have a microphone or call-optimized technology because they are meant to be used for sleep and relaxation, but they may be used for music and podcasts over Bluetooth.
