This article will help you make your earbuds sound balanced.

The sound is quieter or there's no sound in one earbud when I sleep on my side. What should I do?

1. After sleeping on your side, one earphone may be blocked due to pillow obstruction, resulting in Bluetooth disconnection.

2. Sleeping on your side at a certain angle causes the ear tips to be offset and block the earbuds, resulting in no sound or low sound.

We recommend you try the following:

1. Adjust the positioning of your head and pillow.

2. Try larger ear tips.

3. Use a Q-tip with a bit of rubbing alcohol to gently clean the metal mesh filter under the rubber ear tips.

The sound is quieter or there's no sound in one earbud. What should I do?

You can do the following:

1. Use a Q-tip with a bit of rubbing alcohol to gently clean the metal mesh filter under the rubber ear tips. This is best done when sound is playing through your earbuds at max volume. 

2. Fully charge your earbuds and forget the Bluetooth pairing record on your device if you have previously connected Sleep A20 with it.

- Reset the headphones by following tips:

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

-Turn off Bluetooth on your device and then turn it on again to pair it with Sleep A20.
