I can’t wear closed earbuds. here’s a nice review of 12 open buds. I’ve been looking for some myself so please let me know what you decide.
The 9wave NW Studio seems to be the winner in your price range, but you may find others that you will prefer. Still, there is a good discussion in that thread.
