back on the cover. The charging compartment indicator lights
up to indicate that there is power. If it does not light, it means
no power.)

If the headset you received has only one earbud to use for the first time, then you can do as I said, delete the bluetooth name in the phone, take all the earbuds out of the charging box, and then pair it again
