Placing the earbuds back in the case for 30 seconds should reset the earbuds. If that doesn’t work, you can force a hard reset as follows: With the earbuds inserted into your ears but not connected to a device, tap the right earbud touch sensor 7 times. You should hear “…factory reset…battery full…peer pairing”. Follow the same procedure for the left earbud. Remove the right earbud and hold next to the left earbud. You should hear “pairing” from the left earbud. Now try to connect to your device.
