The sponge ear pads on my trusty Sony headphones simply disolved the other day and I was left with a very scratchy surface. I hunted for ages to try and get a replacement part (even though the headphones aren’t that expensive) and finally I tracked some down at Maplin, they’re called ‘Earpads’…which was 90% of the battle. They do make my headphones look as if it has two aphro’s but hey they work.
