Like many of the above I went for the straight-out-of-HMV Sony in-ears and am reasonably happy. Took a little fiddling with the equaliser to get what I consider an appropriate amount of doof, but they are surprisingly bassy for something so small (I'm guessing they must be piezo-driven - I can't imagine so small a coil being sufficiently reliable, reproducable or doofy). They came with three sets of rubber grommits (arf!) which means that they are both comfortable and damned-well stay put.
