I feel extremely lucky to have the opportunity to appreciate this amazing pair of headphones for near 4 years, but recently the left driver of my R10 start to sound quieter and quieter, and now it is unable to produce any sound. I had let my headphone technician friend to diagnose the problem, and it turned out the left driver unit has expired. I have tried every single part store I could find and none of them still have R10 driver units in stock. I have also tried contacting Sony but they don't seem to offer any kind of service for MDR-R10 users anymore. I am desperate to find a working driver or a pair of MDR-R10 with one working driver, thank you all with my best sincerity in advance!!!
