A system (100) and method (400) for unambiguous wireless accessory association between a host device (102) having an optional transceiver (202) and a wireless accessory (110) can include a wireless adaptor (104), a transducer (103 or 106 or 114), and a processor (200) coupled to the wireless adaptor. The processor can be programmed to cause the wireless adaptor to selectively enter (402) a discovery mode, temporarily select (406) a first accessory that responds to the discovery mode, cause (408) the transducer to emit an identity signal detectable only within an unambiguous range, examine (412) a sensed incoming signal to confirm the first accessory is within the unambiguous range, and discontinue discovery (414) and select the first accessory if the sensed incoming signal is determined by the processor to have high similarity to the identity signal.
