Abstract:
A communication device having multiple detachable communication modules includes a first communication module and a second communication module. The first communication module is configured to receive RF signals from a wireless network. The second communication module may be physically attached to the first communication module and is coupled to the first communication module by a wireless link. The second communication module is configured to receive the RF signals from the first communication module over the wireless link and to convert the RF signals into an audible signal. In addition, the second communication module is physically dimensioned so that it may be fitted into or onto an ear of a communication device user.
