Hey guys. I recieved my DT770's from you yesterday and I couldn't be happier in terms of sound. but there's one thing that's bugging me. Inside the earcuffs is lined with a harder material and where it's attahces to the soft stuff, it's quite sharp and cuts into my ears sometimes. Is it supposed to be like this or is it a problem with my headphones? I'm really pleased with them apart from this so I don't want this to spoil it, It there anything I can do to remedy this?
