Embodiments disclosed herein include headphone devices with spatially diverse antennas employing multiple operational modes and antenna switching policies. The headphone device may identify a current mode of operation and wirelessly communicate with at least one external device based at least in part on the current mode of operation. Further, operating in a first mode of operation, the headphone device may cause switching circuitry to selectively couple a first antenna to the common port in accordance with a first antenna switching policy. While operating in the second mode of operation, the headphone device may cause circuitry to selectively couple a second antenna to the common port in accordance with a second antenna switching policy that is different from the first antenna switching policy.
