Recently i got a sony wm-ex600 untested for $50 complete with the box but without the remote control. I want to buy the original remote control but it's a little expensive from my country and i only have the sony wm-ex811 remote control (rm-wm76e). and i think it is not compatible with RC because of the difference in sound mode. wm-ex811 only have EXDBB and wm-ex600 has mega bass, groove, and sound revitalizer
