Sleep A10 (Refurbished)

We suggest trying the following:
- Make sure you wear 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 soft 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.

The rubbing sound is due to the material of your pillowcase. Try using cotton or silk pillowcases.

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.

The Sleep A10 earbuds do not have touch control, so you may have to use a bit of force when pressing the button.

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 the earbuds, throwing the earbuds, strenuous exercise, etc.

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 inside the case flash white 3 times and then flash in sequence. This confirms that the reset was successful and your earbuds can be connected normally.

1. Firmly tap the left earbud twice.
2. Switch in soundcore app.

1. Ensure Smart Switch is turned off.
2. Ensure you turn off Smart Volume Control after you have entered sleep mode.
3. Ensure Smart Switch is turned on and Smart Volume Control is turned off.
4. Ensure Smart Switch and Smart Volume Control are both turned on.

When using the earbuds in sleep mode, you can only adjust the volume in the soundcore app.

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

When the Smart Volume Control feature is enabled, the earbuds automatically start playing sleep music. When the external noise changes, Sleep A10 automatically adjusts the volume of white noise according to the external noise level. You can activate this feature in the soundcore app.
Note: This feature only works in sleep mode and activates when the user has fallen asleep.

No, these earbuds don't support ANC, but they use a 4-point passive noise masking system to block out external noises.

Switch to Sleep mode in the app, then select "Playback Duration" and adjust the time limit.
Note: The default playback duration is set for two hours. You can adjust this setting to your own preference.

In the soundcore app, go to "Control" to change the tap control settings.

In some specific scenarios, the left button on the Sleep A10 earbuds may be accidentally double-tapped, which switches the mode. In this situation, firmly tapping the left earbud twice will switch back to the desired mode.

1. Confirm the charging case has power left (open the charging case to check if there is white light flashing).
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. The first light flashes twice when the left earbud is placed in the case. The third light flashes twice when the right earbud is placed in the case.
3. Use the certified charging cable and wall charger.
4. Check whether the ear tips and ear wings are installed properly.
5. Make sure the earbuds are put in the charging case correctly.

Please note that this doesn't necessarily mean there's an issue with the earbuds, so check your connected devices and surroundings.

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.
4. Check the earbuds by listening to a downloaded song/video if you're using them in music mode.
5. Check the earbuds with another Bluetooth device in a different environment to see if there's a difference.

Your sleep report is given using the data gathered from your earbuds. Sometimes the earbuds can misinterpret certain activities as you being asleep or awake. For example, if you’re wearing them and sit still for a while or you just leave your earbuds out of the case for a prolonged period of time, it may interpret this as sleep. The soundcore app would then use this data in your sleep report, therefore distorting your sleep curve.

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 generates sleep data. If they often move around while sleeping, it may cause the earbuds to misjudge that they are still awake, so no sleep data will be recorded.
1. Open the soundcore app, log in, and connect the earbuds to synchronize data before sleeping (do not put the earbuds back in the case or turn them off after syncing).
2. Make sure you have good signal. Sleep data may take a while to display due to bad signal.
3. Keep the app and firmware up to date.

You need to keep the app active in the foreground for a prompt. You will only get a prompt on your phone not on the earbuds.

The alarm only repeats once and the alarm turns off once you put the earbuds back in the case or when you turn it off yourself. You need to set a new alarm each time you want to turn it on.

1. Connect the headphones to your phone, open the soundcore app, and click on Sleep A10.
2. Click the Settings button in the upper right corner.
3. Click "Add alarm" to set an alarm clock (you can set up to three alarms).

1. Firmly double tap the left or right earbud to pause.
2. Pause it via the soundcore app.
3. The alarm will not go off again after it has been paused.

1. After the earbuds are paired with the soundcore app, you can check it via the app.
2. When the earbuds are in the charging case, the three lights in the charging case blink:
- When three LED lights are white, the case is on more than 70% battery.
- When the left two LED lights are white and the right LED is off, the case is on 30%-70%.
- When the left LED is white and the right two LED's are off, the case is on 5%-30%.
- When the left LED blinks and the right two LED's are off, the case is on less than 5%.

After pairing with a phone successfully, the two lights in the charging case flash slowly.

You can use a clean cloth and rubbing alcohol to clean them.

The earbuds are IPX4 water resistant.
The charging case is not waterproof.
