A speaker assembly, and an associated method, is operable in conjunction with operation of a content capable mobile station, such as a mobile station that stores and plays out MP3-formatted files. A Bluetooth™, or other, transceiver of the speaker assembly communicates with a corresponding transceiver of the mobile station. When content is played out by the mobile station, signals representative of the content are communicated to the transceiver of the speaker assembly, and converted into acoustical form. When the mobile station is operated in a telephonic mode, the speaker assembly operates in a full-duplex mode in which hands-free operation is provided to a user by way of the speaker assembly.
