Just bought the MSR7 a couple of days ago, must say I'm really impressed with the sound! Not so much with the build quality tho, but for AU$279~US$223, I really didn't expect much. I'm using the MSR7 with Jotunheim w DAC and on the go my HTC 10. It sounds great out of the box (not a big believer of burning in, but who knows the sound signature might get better!).
I have had similar sounding headphones in the past, the ATH-R70x, Sennheiser HD700 so it was to my great surprise that the MSR7 sound so much alike but closed! I've also had the ATH-M50x awhile back but comparing them with the R70x I much prefer the less bloated bass and the better refined mids and highs. My daily driver is the HD800S via balanced out from Jotunheim w DAC so when I say the MSR7 sounds great and familiar, you know I'm not kidding
My issue with the build quality is where the joints meet between the head band and the cups, if you wear it a little too tight you can some times hear the grinding of plastics. I believe this can be solved with some lubricant but I haven't had the balls to try yet (not sure what lube to use lol). And the second thing is the adjustment band, when you extend it like say 5 notches or more and you give the cups a little twist, you will hear and feel the metal band grind against the head band. One last thing, the LEFT and RIGHT font just doesn't sit right with me.
Once again, awesome sounding cans! Highly recommended for non-bass heads!
