Abstract
Eyewear for two-way communication comprises a speaker and a microphone. The speaker is supported by an earstem of the eyewear. In some embodiments the earstem is formed into a speaker support loop. The speaker is supported by the loop and held away from the wearer's external outer ear. Speaker position is adjustable in relation to the wearer's ear. An electrical cord couples the microphone and speakers to a wearer unit that includes a wireless transceiver. The electrical cord functions as a neck strap to support the eyewear when removed from the head.
