So a friend of mine came to me with his M50 headphones. He dropped his iPad with them in and it bent the 3.5mm jack. They didn't work at all and the cause was obvious, so I just had him get me a 3.5mm plug from RadioShack and I'd figure I could just cut the wire and solder the new plug on. Well...

Edit: I should clarify, I'm not sure if these are full size or on ear headphones, I've seen websites list them as either, but I do prefer full size ones, in case you want to recommend an alternative.   If you're a TL;DR person, skip this paragraph. I'm really just getting into high quality...
