I bought some replacement ear cushions (Sony) better than 6 months ago. Hell it could be a year. I've been putting off changing them out and doing some mods for fear of screwing up these headphones that I've had since '76. Yesterday I finally opened them up. The mods - I dampened the driver with a felt-file folder stock-felt sandwich. I seated the 50 mm drivers and packed the perimeter of each with rope caulking. With a good seal from fresh ear cushions and the damping the bass response is better than ever and the highs are just south of overly brite. I did not add a reflex dot and I'm happy I didn't because they might be too bright - at least with the LPs I listened to so far - Supertramp, Crisis What Crisis and Pink Floyd, Wish You Were Here. Today I'll try them at work with my iPod and the old Bogey.
