A method of reducing interference by a first wireless audio communication system with a second wireless communication system that is different from the first wireless system is provided. The first wireless system is caused to transmit data packets with a time gap between packets during which the first wireless system is not transmitting. Periodically a long time gap between two packets of the first system is set to be at least as long as a longest time it can take the second wireless system to transmit a data packet even when packet transmission errors are occurring in the first wireless system such that if packets were retransmitted by the first wireless system the long time gap would be reduced to be less than the longest time it can take the second wireless system to transmit a data packet. As such, the second wireless system can transmit one or more data packets during each long time gap during which the first wireless system is not transmitting.
