ABSTRACT:
A cordless digital audio headphone is disclosed. The headphone includes a pair of earphones connected to a headband. The earphones provide audible signals. The headphone also includes a memory unit positioned on the headband for containing digitally stored audio information. A processor is disposed on the headband, and is coupled to the memory unit for retrieving the digitally stored information from the memory unit. An analog to digital converter receives the digitally stored audio information, and provides the audible signal to the earphones.
