| ex71 saga continues.. now with a twist?
Well I have a pair of 71's that have suffered the same fate of the wire going mushy, and I have lost the reciept so Sony wont do anything, and nor will Comet (where I got them). Being a resourceful sort of person I decided that I would try and repair them myself, so here is how i did it for anybody who would like to attempt it (it requires some competence at soldering and a spare half hour to hour, depending on how careful you want to be). First, I took a trip down to maplin (or I suppose if you are reading this from the US then radioshack will suffice) and I picked up some cheap headphones for the wire and plug, some 2.5mm heatshrink, some 1.5mm heatshrink and then I went and picked up a lighter from the pound shop (or dollar store). If you dont have any soldering stuff, just pick up some solder and a cheap soldering iron. Now you have everything you need, you can prepare to sort out your 'phones. First, you need to cut the wires off the cheap headphones. Cut them right next to the speakers, as close as you can get. Now cut two pieces of the 2.5mm heat shrink about 11cm long each, and slip one over each wire that will go to the buds. Now you have the donor wire sorted, you can cut your 71's off the dodgy wire, about 7cm from the bud. Strip the wires from the cheap 'phones, and take about 2cm of the outer coating from the 71's. You will have to use the lighter to carefully burn the acrylic coating off of the inner wires. Now cut four pieces of 1.5mm heat shrink about 7mm long each, and slip one over each wire coming out of both of the earbuds. Twist the corresponding wires from the buds and the donor wires together, and then put a little bit of solder on each twist. Slide the heatshrink you put on earlier over the joints, and you can either run the tip of your soldering iron over it to shrink it or use the lighter very carefully. Now slide the 2.5mm heat shrink up the wire so it just covers about 5mm of the bottom of the actual earbud and shrink it. Ta daa! you should now have some mrd-ex71's that sound good, have a sensible length wire and wont fall apart as soon as you look at them, all for around £6.50! I did this on black 71's, and I cannot guarantee how good it will look on the white ones unless you source some white heatshrink and white wires. Also, I accept no liability for anybody naffing it up, but I hope this helps if you are at a loose end with your earphones and dont want to settle for inferior sound quality or end up paying a bomb for other headphones to get the same sound. Happy Fixing!
