Go to Left designated side, remove ear cup and three screws (small phillips/star screwdriver) on the inner facing. Careful! wires are short, then remove one screw on the green CPU-type board under which is a black plastic covered batterypack with two additional silver screws. Either remove battery or cut the red (+) and black (-) wires close to it. Now remove the outer facing with the logo by prying out plastic snaps with flat screwdriver. Feed the red/black wires into outer area via the holes at the perimeter of the chassis. Replace all screws. Find similar battery or wire in an AA or AAA battery holder, fixed at the outside face with tape, etc. metallic epoxy might work; and use nickel metal hydrate rechargeable batteries which should perform OK. Forget replacing outer face....

mdr-rf985rk has a 3.7 v lithium-ion battery, 610mHa (3x4x0.5cm=2x1.5x1/4") that is wired in. Go to L(left) designated side, remove ear cup and three screws (small phillips/star screwdriver) on the inner facing (note positions). Careful! wires are short, then remove one screw on the green CPU-type board (note position of LED lights) under which is a black plastic covered battery pack with two additional silver screws. Either remove battery or cut the red (+) and black (-) wires close to it. Now remove the outer facing with the logo by prying out plastic snaps with flat screwdriver. Feed the red/black wires into outer area via the holes at the perimeter of the chassis. Replace all screws. Find similar battery (which I am unable to locate at present) or wire in an AA or AAA battery holder, fixed at the outside face with tape, etc. Soldering is, of course, best; metallic epoxy might work; and use nickel metal hydrate rechargeable batteries which should perform OK. Forget replacing outer face.... Best....hgh
