Sick. In a good way.
I was kinda skeptical buying these, but for the major discount I got on Brociety.com I couldn't resist.
I've been through several sets of various kinds of headphones at my job, and the Heshes are easily the best. They cover my entire ear and pretty much drown out any outside noise, which is impressive as I sit on a riding lawnmower alot. usually I don't pump up the volume too much (because I don't need to in order to easily understand my tunes, even over the grrrrring of the mower) but I know that I can without worrying about blowing out the speakers.
Fantastic buy, unless you want some ear buds. these are definitely not for the incognito.
