Okay, they came in.
I'm absolutely stunned. I used Havi B3 Pro 1 as my daily portable and Sennheiser HD600 as my daily at home.
Very prominent lows, articulate and strong. Midrange is flat and not as lush as the Sennie or Havi mids, however they aren't overly thin or hollow akin to Beyerdynamic mids.
Treble is forward and the detail and separation is absolutely spectacular. I am one day in and I am stunned.
Comfort and general fit is a weak spot however I can live with it once I reduce the clamp by wearing it.
From the beginning I've always been interested by this headphone from it's stellar looks and promotional material, and how Audiotechnica has taken the design approach on this headphone. Slightly oldschool and Japanese, yet very modern and refined.
I'll look forward to using this as a critical listening can, whereas using my HD600 for more casual, relaxed listening.
I tried out Brainwavz Pleather/memory foam pads, and while they are comfy as all hell, I found it to ruin the signature. Made the MSR7 more sibilant, slightly drawn back in the mids and less bassy. Toilet paper wedged in the driver supposedly helps. Would recommend you keep stock pads unless you have larger ears.
