Abstract
A wireless headphone assembly has left and right speakers attached to ends of a headphone body, and at least two antennas, e.g., one located at each speaker. Since multiple antennas are used, reception can be improved using one of several approaches, e.g., simple selection of the 'best' antenna, multiplexing antenna input, using diversity algorithms such as multiple input multiple output (MIMO) algorithms, etc.
