My Bose headphones (like these) have finally bitten the dust. The sound was great but, even with 3 different sized ear pieces, they never really fitted that well. In fact, all cheap in-ear ones (like come with ipods as standard) simply fall out, and the Bose ones were always coming loose.
I think my ears aren't good at retaining them - I can stick my fingers in my ears at 90 degress to my skull without any part of my fingers touching any part of my ears (other than the finger tips in the canals); most other people have to come at their ears from the back to some extent (if you can understand what I'm trying to describe).
So, just to limit the field I don't want buckets or things that clip over / round my head. So I'm looking at in-canal ones like the Sennheiser CX400, or over ear ones like Sennheiser CX6, Sennheiser OMX95 VC or Audo Technica ATH-CK9. Cost is an issue, but firstly I need advice on which style is likely to stay put in lugs. "Stay put" includes walking around, commuting on trains etc. but not running or much cycling.
Oh, and for commuting I want them to isolate noise and be quiet for other people - nowt as irritating as noise pollution from ipods.
Appreciating that it's a very individual thing, but any advice appreciated.
