Query: portability at any costs

After I saw all the great reviews my expectations were badly shocked when I found what it actually was all about. The sound is all right and once you were it it is more or less comfort (although all cheepest quality) but getting the headphones on is a real fight. Everytime you pull it on it makes greatest attemps to pull as much hair out of your head as possible. It does not stay in the same setting, so once you put the headphones off the metal connection always goes back to its initial condition.Never would have bought that product if I would have known what was awaiting me
