What's up guys. I just received the beyerdynamic MMX300 yesterday and have been comparing them with my AKG K702s and thought I'd share my thoughts on them. First a little backround

. In the search of the perfect gaming solution for me I have gone through the A40s, AD700s, DT880s, K702s, MMX300s and very soon the PC360s (thanks Nerd

). Of those phones my top two are the K702s and the MMX300s, two very different cans. Ok first off is the K702 -
Pros: Amazing soundstage (depth and width), Pinpoint positioning, Great sound balance and clarity, Comfort (leather bumps are unnoticeable now that they've been worn in), Open design (can hear the wife when I'm gaming, oh wait

)
Cons: Require an additional amp to drive them properly, Expensive, when you figure in the aforementioned amp, Require either a mic mod or seperate mic if you want to chat, Convenience factor (seperate amp/mic solution), Lacks a little bit of low end for impact and immersion.
MMX300 -
Pros: Good soundstage (good depth but nowhere near as wide as the K702), Positioning is very good (can discern footsteps and location pretty well, more on that later), Good clarity and a little more emphasis on low end( Very immersive, powerful impact), Very comfortable (soft velour padding and firm clamp), Doesn't require external amp to sound great (mixamp chat at 12'oclock and is loud enough for me, little to no chat and it's extremely loud), Convenience of a built in mic.
Cons: Soundstage not as realistic as K702 (more of an in your head feel), Bass impact can drown out positional ques sometimes, Closed design (can't hear the wife when gaming, oh wait

), Not cheap.
That's it for now, more later

Cheers
