The problem seems to be spreading to full sized headphones, not only small headphones. There was always the possibility of small headphones like the Sennheiser PX’s being copied but for the most part earphones are the main target. Your Shure E2c’s, Sennheiser CX300’s etc. Now, there also seems to be certain larger headphones that have been copied. Here are some fake headphones and information update.
