Abstract
A headset for wireless communicating with a personal electronic device, such as a wireless phone, provides audio output based on an audio signal from the personal electronic device. A secondary battery in the headset provides power for the headset and is rechargeable from a primary battery in the personal electronic device, thereby allowing the user to recharge the headset in the field. Alternatively two secondary batteries may be provided. One of the secondary batteries can be used to power the headset, while the other is connected to the personal electronic device for recharging from the primary battery. When the battery in the headset becomes depleted, the batteries are exchanged.
