Most of the time, the earbuds that come with your MP3 player are not all that great. In fact, most of the time they offer up only mediocre sound quality. Plus, they can be rather uncomfortable in the ears. But the JVC Gumy Air earphones are meant to provide good sound and a comfy fit.
They look rather stylish and are comfortable to wear. However, not everyone may enjoy their fit. It's an individual thing, so if you're looking for a one-size-fits-all solution, you won't find it here.
