If the ON/OFF LED does not glow white when you turn your headset ON, it requires charging**.** To charge the battery, plug the USB charging cable into the USB-C port located on the right-side of the headset.\ Then, connect the other end of the USB charging cable to a power outlet or PC/Mac. The length of time it takes to fully recharge your headset depends on the remaining capacity of the lithium polymer battery. Charging can take up to two hours. If the headset is unused for a long period of time, the battery will become heavily depleted of charge. If this happens, you may need to charge your headset for 24-hours. If you have any issues charging your headset, please contact the EMOTIV Support team.
