I know this has been asked before but I could not find my answer in previous threads. I hated the iPod earphones that came with my Mini. Got some cheap Philips ones that had better sound quality but less bass. Then Got the Sony Fontopia EX-81 in ear phones and like them a lot. How ever when I am running and I sweat, they have a tendency to slip a little and I have to push them back in. I am looking for ~$50 headphones that aren't bulky, they can be in ear or the regular outer ear, and must have good sound insulation like the Sony ones I had. Some people I say like those Grady SR60/80 but I would like to avoid those chunky things. Suggestions?
