Is there any way to repair or replace the earpads on my old headphones? There's a seam on the inside that has split on both of them exposing the foam inside and its starting to get irritating. There an easy way to maybe glue them back together or a place that sells replacement pads? I'd rather not be forced to buy a brand new pair of headphones when these still sound great, just getting a little worn out on the earpads.
