I recently was at Best Buy and tried on some Bose headphones. I forget how much they cost but they were crazy expensive. With these headphones, you can NOT hear anything other than whats coming thru the headphones. Totally blocks out all outside sounds. If someone is yelling at you, you cant hear them. You couldnt hear a siren. I dont think I like that idea. Seems a little dangerous.

Personally, I use some pretty cheap Headcandy headphones that are big and bright and noticeable. When I am in the gym, I want it to be obvious I have headphones on so lessens the chance someone is going to interrupt my workout and also people arent as likely to think you are a rude asshole. LOL

I sued to like the small ear bud types. I like those if I am running. But in the gym, I like a big set, of course they can get pretty damn sweaty, and not as comfortable as the bud kind. What kinds headphones do you like? Are the expensive ones all that worth it?
