Why does only one earbud of the REDMI Buds 6 Play have sound when paired with Bluetooth?

The reasons are as follows:
1. Poor contact with single-sided earbud results in only pairing with single-sided earbud;
2. Unilateral earbud will shut down due to low battery;
3. There is any dirt blocking the speaker in the earbuds and earplugs;
4. Check whether the earbuds are soaked in water and sweat, causing a short circuit and freezing;
5. Bluetooth disconnection of left and right earbuds.
To resolve the above problem, please refer to the following methods:
1. Please put the earbuds back into the charging case and confirm that the indicator on the charging lid will light up when they are put into the charging case. Repair the earbuds with Bluetooth to restore them;
2. After confirming that the earbuds are in good contact, put them in the charging case and charge them for 10 minutes. Pair them with Bluetooth again to restore them;
3. Check and clean the earbuds and earplugs for dirt;
4. Please try to restore the factory settings. Please put the earbuds in the charging case, open the lid, and press and hold the charging case button for 10 seconds, and the indicator will flash. The REDMI Buds 6 Play will be restored to the factory settings.
5. It is recommended to send it to the after-sales service center for disassembly and inspection.
