I bought these about 6 months ago, wooed by the brand name. These were my first "in ear" headphones. Contrary to other reviewers, I think they are great (and picked them up for a lower price). For comparison purposes, I don't have a history of buying expensive headphones but I do have a chunky set for music equipment at home. I wanted a pair which were small to carry but wouldn't fall out while doing sport.

My comments:
- they come with three ear size pieces, the smallest of which fit my ears perfectly, and I generally take very small sizes for things like this. The largest size seems pretty big.
- the fit is so snug that I can wear them whilst cycling or jogging and they don't fall out
- the ear pieces can be removed and washed
- the sound quality is excellent, plenty of bass and real stereo (assuming you stick the right one in the right ear, left one in the left ear)
- they come with a a little plastic bit which you can wrap spare wire around. This means you can make the lead as long or short as you like, and not have loads of trailing lead to get caught in things or tied in knots - really handy.
- they seem to be quite robust as I stick them in my bag with loads of other stuff and no sign of damage yet
- they don't come with a carry case, although that personally doesn't bother me
