My JVC HA-D990's pads are warning out badly. Where can I buy a replacement pads? I search in JVC and found a pair of pads for 27 dollars w/o shipping? Will the beyer velour pads fit into my D990? I also have the V6, and the earcups on this Jvc is a bit bigger than the V6. The size of Jvc's pads should be about the same size to Sony MDR-7509 and mdr-v600. Any idea? Thanks.
