1. A system comprising:
a mobile device that establishes a duplex phone connection;
a wearable device that connects with the mobile device via at least one wireless connection and that receives processed audio data from the mobile device, the wearable device comprising:
a body having a first portion and a second portion,
a first speaker connected to the first portion of the body,
a second speaker connected to the second portion of the body,
a first microphone connected to the first portion of the body, and
a second microphone connected to the second portion of the body;
a memory that stores instructions; and
a processor that accesses the instructions in the memory, wherein execution of the instructions by the processor causes the wearable device to perform functions, including functions to:
connect the wearable device to the mobile device; and
for a duration of the duplex phone connection:
selectively activate the first and second speakers to emit respective first and second output sound signals and selectively activate the first and second microphones to capture respective first and second input sound signals; and
alternate between activating the first speaker to emit the first output sound signal and the second microphone to capture the first input sound signal while the first microphone and the second speaker are deactivated and activate the second speaker to emit the second output sound signal and the first microphone to capture the second input sound signal while the second microphone and the first speaker are deactivated.
