JVC HA-SA 500 is not only sensitive to different earpads and foam inserts but also the damping behind the drivers. I tried dampen the cups with a piece of 2mm bitumen and it only decreased the bass (maybe a bassport in the cups could help, so the drivers can get some air). I think the drivers in the JVC HA-S500 requires hard work if you want to do a driver transplant.
