Working fine for around a year now, suddenly R earbud neither shows on or off

Hi friend, 

Thanks for choosing EarFun. Sorry for the inconvenience caused.

As for the issue you encountered, we kindly suggest you try the below steps.

1. Please use the charging cable to charge the case for 2 hours.

2. A. Use a toothpick to gently clean the metal contacts on the earbuds and charging case to avoid dust or wax stains;

B. Clean the contacts of the earbuds and the charging case with an alcohol cotton swab; (especially the groove of the earbud contacts);

C. Rub them with clean napkins, press the earbuds with forces to eliminate loose contact with the case and charge them for around 1.5 hours to try it out. (Ensure the case has enough battery life simultaneously).

3. Reset and reconnect the earbuds per the updated steps:

Step 1. Delete the old connection from the Bluetooth device.

Step 2. Place the earbuds into the charging case and make sure they are being charged.

Step 3. Keep the charging case open, then press and hold the charging case button for 8 seconds until the LED indicator on both earbuds flash in purple 3 times.

Step 4. Search and reconnect “EarFun Air".
