Adapter is configured to plug into port of personal digital audio player. Speaker system is in communication with adapter, and comprises multiple acoustic transducers, programmable processor circuit, and wireless communication circuit. In first operational mode, processor circuit receives, via adapter, and processes digital audio content from personal digital audio player into which adapter is plugged, and the multiple acoustic transducers output the received audio content from the personal digital audio player. In second operational mode, wireless communication circuit receives digital audio content from a remote digital audio source over a wireless network, processor circuit processes the digital audio content received from remote digital audio source, and the multiple acoustic transducers output the audio content received from the remote digital audio source. ## Claims ### Claim 1 (canceled) ### Claim 2 Headphones comprising: a pair of first and second wireless earphones to be worn simultaneously by a user, wherein each of the first and second wireless earphones comprises at least one acoustic transducer for producing audible sound;
