For the first time I'm so excited about a product that I decided to write a recession. First I want to say that I a Creative MuVo² headphones - use MP3 player. Previously I had the MX 400 from Sennheiser, with whom I was very satisfied, but my "new" surpass the MX-series by far. Since the handset to be introduced directly into the ear canal, the ear pads made of rubber isolate outside noise almost completely. In addition, other people do not get (eg the train) with, what we hear and are not unnecessarily harassed (which unfortunately all too often the case). When you first try at first I thought that the bass was pretty low or almost non-existent. Later I realized, however, that the earphones were not right in there. I hear primarily metal and can only say that the sound is crystal clear and the Bass said in German is just awesome. Since my ear canal appears to be relatively narrow, it is connected to some effort to introduce earphones (even the smallest ear adapters). If they sit again, but then bombproof and also comfortable. For better sliding can the ear adapters also of external grease with a little cream (then the whole flutscht better ;-) Total are ear adapters in 3 different sizes with. It's a shame that Amazon currently does not offer this handset, otherwise I would have ordered there. So strong buy recommendation
