1. Please make sure the battery power is sufficient. It may be because the battery level of the phone or the buds is low or or the battery has been drained;
2. Ensure that the buds are properly connected to your device via Bluetooth (less than 10 meters). Sometimes, a weak or unstable connection can cause audio issues. Try disconnecting and reconnecting the buds to your device;
3. Check the buds for any debris or visible damage that might be affecting the sound quality. Clean the buds carefully using a soft, dry cloth or a cotton swab to remove any buildup;
4. Try using the buds in another environment. This can help rule out the signal interference in your previous environment;
5. Test the buds with a different device to see if the issue is related to your original device. This can help determine whether the problem lies with the buds themselves or with your primary device.
6. Reset your buds, delete the connection record on the mobile phone, restart the mobile phone, and then pair it again.
