I7s tws charging: i like the charging case or pod. there is a built-in battery, so not only does it protect the earphones, it can also charge the pair without being connected to a wall socket. in other words, the pod works like a power bank for the headphones. and it looks super cool too charging the airpods that way.
besides being able to charge the i7s airpods by plugging any regular micro-usb charger to the pod/carry case, the sales box includes a usb-to-pin charger that can be used to charge each headphone directly. the pin charger plugs into the base of the stem of each headphone.
