Any standard SD card containing your big corporate record label-approved, legitimately-purchased content (and other music) can be inserted into this wireless headphone's trap door and rocked like a hurricane. Wireless headphone + integrated content player in one. Who says no man can serve two masters? (Please note: This headphone does not transmit wireless signals)
