I want to compare these and hopefully a few others and write up my observations. The M-80 and Aviator are easy enough for me to buy, and hopefully return, but I'd rather not do it that way if someone's willing to give theirs up for, I don't know, a couple of weeks? I wouldn't want to buy something thinking I'm 100% likely to return it; seems kinda dirty. Maybe one will be a keeper, but the others wouldn't be. You guys get me, I don't need to push it in any further. I want to get a decent snapshot of some good headphones that include 3-button mic remotes that will be used unamped on-the-go out of an iPhone or unamped at home on a Macbook Pro. Any other headphones with remote would be welcome too, like the Q460 or PX 200-IIi. Brave souls?
