Wireless systems having a plurality of physically and electrically-separated data sinks. An exemplary wireless system includes first and second data sinks having no physical or electrical connection therebetween. The first and second data sinks each include a wireless communication device, e.g., a radio frequency (RF) receiver or transceiver configured to receive data signals over one or more single-access wireless links or over a multi-access wireless link. The first and second data sinks in exemplary embodiments may comprise audio data sinks, e.g., stereo speakers, left-ear and right-ear earphones (e.g., earbuds or canalphones), left-ear and right-ear circum-aural over-the-ear headphones, etc. At least one of the first and second data sinks may also be coupled to a wireless transmitter and accompanying data source (e.g., a microphone or sensor), so as to provide, for example, two-way communications between a user and an external data device (e.g., a cellular telephone).
