okay so in this video just showed up on goodmusicallday there are DT770s, M50's and the black lady wearing Mr Speaker mad dogs? Pretty impressed with my self that I named all those off the top of my head lol. Pretty great music video and song, some of the samples remind me a lot of Manic Focus if anyone is familiar.
Good eye! I didn't spot the m50, but I saw the Fostex. Those aren't actually Mad Dogs, just t50rp's. they're pretty common work headphones. I've seen a couple in labs on my campus.
