1) On a new unit, a protective plastic film (poly) is placed inside the charging case. If it is not removed, it can sit on the charging pins between the earbuds and the case.

2) With the poly on the pins, the earbuds will not charge, may not power on, will not enter pairing mode and will not connect to the mobile or the Noise Audio App.

3) Take both earbuds out of the case and remove the poly completely from the case. Check both earbud slots and make sure no piece of plastic is left on the charging pins.

4) Place the earbuds back in their own slots (L in L, R in R), close the lid and charge for 30 minutes.

5) Open the lid and pair the earbuds again with the mobile and the Noise Audio App.

Note: For any new unit with a no charging, no pairing or not connecting complaint, always check for the poly inside the case first.
