One end of the headset plugs into the device at the top , and the other divides into two cables, with an ear bud on the end of each of those two cables. The microphone and button are located on a small plastic control on the cable, about 20 centimeters from the ear buds. The microphone and the talk button are on opposite sides, so when clicking the button on one side, try to avoid covering up the microphone on the other side.
When the head set is connected to your device, you can use the button on the head set cable, as the talk button. This means that you will not need to hold the device, leaving your hands free for other things. You can continue to use the talk button on the device while the head set is connected, however, you must speak into the microphone on the head set cable.
The stock headset can be replaced with other headsets depending on user preference regarding; comfort, sound quality, budget and ease of use. Bluetooth enabled bone conducting headsets have proved to be popular with users.
On one end of the cord is a small, rectangular, USB plug, which connects to the device. On the other end of the cable, there is a larger rectangular metal shape which plugs into the charger plug. The charger plug plugs into an ordinary power outlet. If you are using a USB charging device, you will not need to use a charging cable plug.
If lost or broken, the charger and power cord can be replaced with other standard mobile phone chargers of the same type.
