Sleep A20 | Des écouteurs pour dormir offrant un confort inégalé

We suggest trying the following: - Make sure you are wearing the ear tips and ear wings correctly. - Choose the ear tips and ear wings that fit your ears the best. We recommend that you start with size M ear tips and ear wings. - Insert the earbud into your ear and find a suitable position for the best fit. If the earbuds are too deep in your ears, it may affect the Bluetooth connection. If you experience connection issues, we recommend that you replace the ear tips and wings with larger ones. - When using them in bed, try a different pillow. - Use soft pillows. Pillows that are too hard may exert more pressure on your ears if you sleep on your side, which can affect the connection to your phone. - Do not use water pillows or pillows with metal or magnetic components.

1. Replace the ear tips with other sizes, and see if it improves the feeling of pressure in the ear. 2. If you feel stuffy or too sealed, you can replace the breathable ear tips. But please note that this will affect the noise masking effect. 3. When using them in bed, try a different pillow. Pillows that are too hard may exert more pressure on your ears if you sleep on your side, which can affect the connection to your phone. 4. Do not use water pillows or pillows with metal or magnetic components.

1. Check whether it is worn correctly 2. If you feel stuffy or too sealed, you can replace the breathable ear tips. 3. Try different ear tips or softer pillows.

The rubbing sound is due to the material of your pillowcase. Please check whether you are wearing the earbuds correctly, and try using cotton or silk pillowcases. (Suggestion: Some pillows are made of a smooth material, which easily comes into contact with the headset to produce friction sounds, you can adjust the wearing angle of the earbuds, or add a pillowcase to the pillow.)

1. The first time you open the charging case you need to remove the insulation under the earbuds before putting the earbuds into the charging case. You must open and close the charging case once before you can turn on the earbuds. 2. After opening the charging case, the earbuds will automatically turn on. They turn off when you place them in the charging case and close it. You cannot turn the earbuds on and off manually without the charging case.

The Sleep A20 earbuds do not have touch controls, so you may have to use a bit of force when pressing the button.

1. When the earbuds' G-sensor vibrates, it may recognize it as a double tap, resulting in a false trigger. To avoid this issue try to avoid dropping or throwing the earbuds. 2. False triggering is possible when adjusting the position of the earbuds while wearing them. 3. There is a certain probability that a double or triple tap will be triggered when placing one earbud into the charging case, resulting in mode switching or volume change, which is not a malfunction, but rather the earbuds triggering a tap by mistake when placed in the case. This is a common issue with the sensor.

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 on the case flash 3 times. This confirms that the reset was successful.

1. Pair the earbuds with your phone. Currently, the soundcore app is not available for computers or tablets. 2. Open the soundcore app, choose Add Device > Headphones, Speakers, and Frames, to find your device. 3. If you cannot find Sleep A20 in the list, please choose Set up Manually > Sleep > Sleep A20. 4. If you cannot find Sleep A20 in the list, please update the app to the latest version. Alternatively, you can uninstall then reinstall the soundcore app. If the problem still persists, please contact us and let us know which version of the soundcore app and phone model you're using so we can further assist you.

1. Firmly tap the left earbud twice. 2. Switch via the soundcore app. 3. After turning on the Smart Switch, the earbuds will automatically switch to Sleep mode when the earbuds detect that the user is asleep, and switching to Sleep mode will play built-in sleep sounds by default.

1. Adjust the volume bar manually in the soundcore app. You can only adjust the volume in the soundcore app. 2. You can adjust by tapping on the earbuds (when using two earbuds together, the default is three taps on the left earbud to decrease volume, and three taps on the right earbud to increase volume, users can customize the Tap function in the soundcore app)

When the earbuds detect that the user is asleep, they will automatically pause sound played via Bluetooth, switch from Bluetooth mode to Sleep Mode, and automatically play sleep sounds. If you want to listen to Bluetooth music again, firmly tap the left earbud twice or change mode via the soundcore app to switch back to Bluetooth mode. Double-tap the right earbud to play Bluetooth music again.

The G-sensor of the earbuds may be recognized as a double-tap by the vibration, which may lead to a false tap, and it will be misrecognized as a double-tap on the left earbud to switch the playback mode with low probability, so you can double-tap on the left earbud to switch back to the mode you need to use, or you can set the double-tap as no function trigger.

1. Confirm the charging case has power left (open the charging case to check if there is a flashing light). 2. Clean the charging pins with a dry cloth and rubbing alcohol. This is to ensure all charging contact pins on the earbuds and charging case are completely clean and dry from sweat and water. Then put the earbuds correctly into the case. 3. Use the certified charging cable and wall charger. 4. Check whether the ear tips and ear wings are installed properly. And make sure the ear tips and ear wings do not cover the charging contacts. 5. Make sure the earbuds are put in the charging case correctly. The charging contact part needs to be aligned.

- Standard playtime in Bluetooth mode is 8-10 hours at 50% volume. - Standard playtime in Sleep mode is 14 hours at 50% volume. Note: - Setting an alarm will take up 20% more battery so the playtime will be reduced to 80%. - The battery life of electronic products will be shortened with the increase of usage time. The battery life of the earbuds shortens over time due to factors such as battery aging, excessive charging times, ambient temperature, and frequency of use. These factors can lead to a gradual reduction in battery life, affecting how long your earbuds will last. - Battery playtime in Bluetooth and Sleep mode is obtained from testing in the soundcore laboratory using the earbuds' default settings; no smart volume control (Sleep mode only), and 50% volume. The actual playtime may vary by volume, audio source, environmental interference, usage, etc. We also recommend you try the following tips: - Fully charge your earbuds. - Turn on the smart switch, and the earbuds will enter Sleep mode after detecting the user has fallen asleep, which can prolong battery life. - Try to close the soundcore app in the background of the mobile phone to reduce power consumption. - Do not turn off the device's Bluetooth, turning off Bluetooth during sleep will cause the earbuds to be in Bluetooth search state for a certain period of time, which will consume power a little faster.

Earbuds: Approximately 90 minutes Charging case: Approximately 2 hours

5 times on full charge.

About 20% difference in battery life between the left and right earbuds is within the normal range.

1. Make sure you're wearing the earbuds correctly. 2. Try another set of ear tips and ear wings in a different size. - Please note that if the earphones are too deep in your ears, it may affect the Bluetooth signal. Try larger sizes to reduce the in-ear depth of the earbuds, which may improve the connection stability. 3. This doesn't necessarily mean there's an issue with the earbuds, so check your connected devices and surroundings. Bluetooth signals may be influenced by obstructions, such as walls, pillars, home appliances, Wi-Fi, and more. To ensure a stable connection for these earbuds, we recommend avoiding such obstructions and using the earbuds in an indoor environment. 4.

Sleep data is acquired via the earbuds according to the state of the person wearing the earbuds when asleep or awake, so as to generate sleep data in the soundcore app. Since each person is different, there may be an error in the detection.

How sleep detection works: The earbuds judge whether the user has fallen asleep by their movements. If within half an hour, the user barely moves, the earbuds determine that they have fallen asleep and begins generating sleep data. If they turn over frequently or make big head movements while sleeping, it may cause the earbuds to misjudge that they are still awake, so no sleep data will be recorded. 1. The latest sleep data needs to be updated by connecting the earbuds and syncing them to the soundcore app. 2. You don't need to open the soundcore app every time you go to bed to sync data. 3. You'll need to connect your earbuds to the soundcore app on a regular weekly basis to sync your data.

You need to keep the app running in the background for a prompt. You will only get a prompt on your phone not via the earbuds.
