Summary: I swear by these as they are the only earphones that fit my ears. I didn't know that I had particularly strangely shaped ears, but I find regularly sized earphones tend to hurt after a few hours of use. I can wear these all day with no problems. I've bought many pairs of them now, since they are on the fragile side, luckily they aren't too expensive.
Summary: These sound really good. I found them a little uncomfortable and loose at first so I fitted the rubber ring and foam pad on each earpiece and now it's a very snug, comfortable fit and gives a half-decent level of isolation from the outside world too. I'm surprised at the clarity of the sound, I can now hear more things going on in the music than before with my (what I thought sounded decent) Sony MDRE828, now discontinued.
Summary: Excellent sound quality with fantastic bass response. I find the in ear type headphones annoying, the bass transfer is great but I find sounds such as me breathing or my feet hitting the pavement are very intrusive and pretty much all external sound is cut off (which is probably the idea, but I find it useful to have some awareness of cars and buses etc) and these are the best I've found that aren't like that.
