As the title asks, I need to know whether these Shure E2C phones will fall out while running. I've just blown £30 on Sony's new 81 in-ear phones, which gradually fall out. Its so annoying when the music gets quieter and quieter So... yes or no? Will they fall out? I could do with as many answers as poss please before eBaying it. Dont wanna waste MORE of my hard-earned. My other option is to try the large sized ear buds that come with the Sonys, but I havent high hopes for them, despite their great sound quality. I've also tried some Koss phones, which were even worse . PLEASE HELP!
