Abstract:
1. A wireless headphone, comprising: a body configured to fit onto a user's head, the body defining opposed ends; a first speaker coupled to the body and juxtaposed with the first end; a second speaker coupled to the body and juxtaposed with the second end; at least first and second antennas coupled to the body; and at least one wireless receiver supported by the body and electrically connected to at least one of the antennas, wherein if the first antenna is selected, it is used for providing signals to both speakers as long as the first antenna provides acceptable performance, the second antenna not being used, the second antenna being used in lieu of the first antenna when the first antenna no longer provides acceptable performance, wherein packets received by the receiver are tested for both (1) signal strength and (2) packet error rate, wherein an indication of unacceptable performance can result only in response to at least one packet having an error rate outside an error tolerance and signal strength below a signal strength threshold, wherein an indication of unacceptable performance cannot result otherwise, such that an antenna switch is not made unless an antenna has both signal strength below the signal strength threshold and packet error rate outside the error tolerance.
