I think the MSR7 may very well be my favorite closed portable headphones from Audio-Technica ever!
No, they're not the best-sounding headphones that I've heard, because that'd be overstating things. But when it comes to closed portable headphones, and more specifically the ones I've heard made by Audio-Technica, which includes the ES5, OR7, FC7, and ES7, the MSR7 is easily the best! I'd also say these hands-down beat some of the other closed portable headphones I've heard in recent years like the V-MODA M-100 and Beyerdynamic DT1350!
They do sort of have a "monitor"-like sound to an extent, which helps them sound unusually hi-fi-ish for the price and achieve a degree of clarity that I've
never heard at this price bracket period. Historically whenever I've used any <$300 headphone on my system, I've always found something lacking that made me want to go back to a more expensive headphone, but the MSR7 is literally the first <$300 headphone that doesn't make me feel like I'm missing anything that a more expensive headphone would provide.
And they do an even better job with movies and gaming too. In fact they're my new favorite headphones for gaming and have beaten out the ES7 for that purpose! Crysis has never sounded better.
The MSR7 would be an immediate replacement for the ES7 if it weren't for the comfort issue, which I'm still working on....
