A:Answer The MDR-ZX110 does not come with a 3.5mm to 1/4 inch stereo adapter. You must provide that on your own, but they are cheap and can be found at pretty much retail store that carries audio equipment (BEST BUY, Walmart, Kmart, Target, etc.) for very cheap. To be clear the ZX-100 "Plug" on the cord is 3.5mm to fit a 3.5mm jack (the plug is on the cord and the jack is part of the equipment you are plugging into).
