My 14-year-old daughter has ear canals that are smaller than usual. The earbuds that come with Ipods and most other commercially available earbuds are too wide to fit comfortably in her ears--in fact, she says they hurt her ears. The Jbuds are the exception. They come with 3 different sizes of ear inserts (small, medium, large). The small ones fit her ear canals comfortably, and, just as importantly my daughter thinks they look cool.
