I haven't had the chance to listen in on the others aside from the Bose cans and this is what I have to say about the Bose cans and the Monsters.
Bose cans sound pretty flat, there is nothing at all special about them, for the price they simply are not worth it. Even though I do own a few of them, and listen to them on occasion, I wouldn't buy another set. As a speaker person, more then a phones person, Bose has been on decline for some time.
As for the Monster cans, I simply protest there business. They've been pulling a lot of cheap shots on other small businesses who have "Monster" in their name (such as the monster mini-golf joint). Their cables aren't that great, and for the most part are just over priced. I haven't heard their cans, but I'd stay away from the company simply because of this.
