I had some SuperFi 4 headphones for over a year. They were brilliant! Until the day I left them in the socket on a plane, got up and then sat on the connector...not something I can blame on anyone but myself! These were all around £40-45 last week so a good price! I can't say enough about them, all the negative reviews appear to be people who end up saying they don't find ANY in-ear headphones comfy...
You get lots of different sizes of silicone (and possibly foam aswell, I did with my SuperFi 4 and these, but my friend did not with his 4...) ear pieces so finding a snug fit should not be a problem.
For iPod, iPhone, MP3 players, and BlackBerry devices with a standard 3.5 mm jack.
