I like
these. Not only do the stay in my ears, but they sound great and the wood design makes them the most attractive ear buds I've ever owned. They're $25 at Amazon, and they are the in-ear rather than the on-ear type, but I think they're worth it. It's a shame there's no way to try before you buy. They fit my ears, but they may not fit yours. I'm on record as saying that the Apple ear buds weren't made for human ears, as the only way they'll stay in mine is with duct tape, but I've since heard other people who say they have no problem keeping them in their ears.
