Go in to the Apple Store after release, they usually have models available for trying them out. They keep em stashed away in the drawers of those big tables, and use alcohol wipes to clean them before you try em on. I didn't know this until I recently went in to look at the Powerbeats and one of the employees asked if I wanted to try them before buying. Good thing I did, they didn't fit my ear canal comfortably.
