Hi, all... I'm new here! I need help with two things: 1) My boyfriend has an MZ-R70 MD player, but the headphones are dying, and I need replacements. I've noticed that the headphone jack has an interesting kind of connection. It looks like it has two parts. One is a regular headphone jack, but it is next to a small, flat opening that looks similar to (but is NOT) a USB-A port (its almost the same shape, but smaller). The headphones connect through both of those at the same time, if that makes sense. I've looked high and low online, but can't find a product number for replacement headphones that have this special connection. Does anyone know how I could go about replacing them? 2) The other issue us that MDs are not really available in the US anymore, and those that are seem to be devoid of the optical input the MZ-R70 has. I'd love to find another MD player with an optical input, or at the very least, a stereo line-in input (I just want to avoid any computer dependency whatsoever). Thanks very much in advance!!
