Tonight, I started getting some rattle in my left side and sounds like a partially blown driver or one on it's way out the door. I have the HEADPHONELOUNGE Vibro Mahogony cups and aftermarket wire. The soldiering is in great shape and there is no loose pieces in the wood cups so I have narrowed it down to the driver. I have googled and found very little info on aftermarket or factory replacement drivers for these headphones. Does anyone know where I might be able to pick up a pair of these drivers? Thanks for any help!
