Well, I've been using the Samson sr850 since my Audio-Technica CKS77 crapped out and I've got to say....they're pretty amazing. For my first set of open cans I find that the air circulation combined with the great detail and soundstage great for gaming. Bass response is pretty epic too. It's not bloated but goes pretty deep. As a gaming only option, I don't know if there's anything better under $50.
I mean, I've tried the Audio-Technica M50, WS55, M-Audio Q40, Phillips Citiscape Uptown and Downtown and this beats them all in gaming/movie performance. Nice and Light with no clamp and a self-adjusting headband. Very comfortable. Music souunds pretty good too.
Makes me want to look into the Q701/HE-400/HE-500/HD650 but I don't want to have to mess with expensive amps. I'll just settle for the Fiio E09k.
I wish Astro would stock their Mixamp already. They said by the mid of November.
Interesting perspective on the Samson. Wish I had money to slake my curiosity about the SamsonSR850 and Takstar that people are starting to enjoy, but I already "got serious" with the Q701. And just to point out from your "have to" mess with expensive amps comment: even without an expensive amp, the Q701 performs superior to any other headphone I've heard. It's just that, experiencing this, it changed my mind about eventually exploring amping. Feeding music into my home receiver definitely scales up the experience further. I figure my Yamaha's solid-state amping is a decent representation of what a powerful SS amp can do for the Q701, so that's why I'm trying a tube amp next.
