For some odd reason, every one thinks your cooler when your wear Beats. I might have bought some refurbs, just out of curiousness, but after trying out my friends Tours, I just couldn't. There was no way I could get a good seal with them. I've tried all of the tips, all of the 10 tips that come with the M11+,Comply Foam Tips, and even Sony Hybrids. Not one fit me right, the first earphone I ever wore that wouldn't fit me no matter how hard I tried. Isolation was surprisingly mediocre also. Might be cause of the poor fit the Tours provide, but my M11+seem to perform almost as good or even better. Sort of odd that the M11+ is only a third of the price. Using the Foam Tips ( or an sort of tip actually ) I just couldn't feel the bass that even the M11's do a better job on.
