Power bank and holder in one. O2 Bluetooth Earphone is a compact unit that easily fits in your pocket.
Tangled cord and power shortage are earphone annoyances in everyday life.
O2 not only keeps cords neat, its charger has a built-in power bank
that charges the earphones while you're carrying them around.
When not in use, O2's magnetic design allows the earbuds to connect together as a necklace
so you can keep the earphones around your neck for easy access.
