Troubleshooting:

If you have trouble connecting the headset and smartphone:

Confirm earphones and mobile wireless are paired and the wireless device function is enabled.
Ensure earphones and mobile device are within 15m, and there are no walls or obstructions between them that might affect wireless reception.
If you want to use only the right earphone, remove it from the charging bin, place the left earphone in the charging bin, and close it. Wait 2 minutes for the smartphone to detect the right earphone device name "Macaron".
