WEARING
Choose
the ear tips and ear wings that fit your ears best. The earbuds come with the M
sizes of ear tips and ear wings pre-installed.

To better block out noises, insert the earbuds into your ear canals and turn gently until the ear wings are wedged against your ear ridges.

Sleep A20” on your device’s Bluetooth list to connect.
When pairing, the second LED indicator on the charging case will start flashing. After the pairing is successful, the second LED indicator will stay on for 1 second and then go off.

USING SLEEP A20 WITH APP
Selecting Listening Mode You can switch between Bluetooth Mode and Sleep Mode via the soundcore app or by tapping the left earbud twice. The touch controls can also be customized in the app.
- Bluetooth Mode: Connect to other third-party apps for your favorite audio content.
- Sleep Mode: Listen to the soothing sounds downloaded onto your earbuds without having to interact with apps or other devices. This ensures a sound sleep free from disturbance by phone notifications and alert tones.
Smart Switch and Playback Settings
- Smart Switch: Enable this feature to automatically switch from Bluetooth Mode to Sleep Mode when you fall asleep. You can also choose the audio you want to use after sleep (e.g. sleeping sounds or masking sounds).
- Playback Settings: Customize the duration of playtime.
Smart Volume
Smart Volume: In Sleep mode, the mic of your phone will detect changes in
ambient noise. When there is a consistent increase or decrease in volume, the
audio volume will dynamically adjust according to external noise changes,
providing a noise masking effect that is more adaptive to dynamic
environments.
Notes:
- Sleep A20 does not have an ANC feature.
- This feature is only effective in Sleep mode.
- It is necessary to ensure that the earbuds are connected to the smartphone, and the app must continue to be active (do not manually close the app).
- The earbuds themselves do not have microphones; they rely on the smartphone’s microphone to monitor ambient noise levels (only detecting changes in environmental volume, without recording or recognizing the content of the sound in any form).
- This feature requires more than half an hour of use before a corresponding report will appear (you will see a one-time monitoring result either when you manually turn off the feature or before the next use).
- This feature provides a maximum volume limit of 65dB. The earbud volume will not continuously change with the external environment’s volume level (in compliance with the World Health Organization’s recommendations for hearing protection).
Sounds
In My Library, you can transfer a total of four Sleep Sounds
tracks into your earbuds.
For each track, you can mix up to three white noise sounds and fine tune them
for your ideal listening ambiance. After the adjustments are made, Tap
Transfer to upload your customized audio mix to the earbuds.
Please note that once the audio has been transferred, it cannot be modified.
Sleep Monitoring
- Sleep Monitoring: The earbuds can monitor your sleep data (including sleep stage, sleep positions and the frequency of rolling over) to provide a detailed report.
