Just wanted to show this picture of how a j-cord should be worn
Notice the shirt clip clipped some way below the j-split (which is behind my neck) and clipped high up on the left (right in the photo). This gives sufficient play to the cable to both buds and will let you wear them as comfortably as with a Y-cord, with the added bonus that they don't dangle in front of you as much getting in the way of things when you take them off your ears.
Hmm, that looks significantly better than what HiSound tried to do with the Popular IEMS.
I still don't like J-cords though, they're too limiting IMO in which pocket you have to have your music player in...
