I own a pair of Sony Wireless Headphones Model TMR-970R / RF970R. I am in need of an Owner's Manual and a new power cord. I have tried looking on line and the model number never pops up except on message boards saying the same thing. I have looked at other model numbers as listed in the chat boards but the pictures of those models do not look like My headphones. I really do need help finding a replacement power cord and a new oweners manual. Please help.
