I go thru several brand , and a lot of cash , try to find that combination of function and form . these earbud come with 3 size of ` ear plug ' , and the small one actually fit . what a relief ! I take a while , but I finally find a pair of earbud that fit and sound great ! I have be listen to my mp3 player everywhere from work to the beach of Cancun , and have be extremely happy with the sound quality and comfort . you will not be disapppoint if you buy these .
