Just thought I'd share my initial impressions with these sweet headphones.
I bought mine from Focus Camera when they had the refurbished sale. They showed up with a defective left driver. Focus wouldn't send another pair right away, so I would have to gamble that one would be available once my defective pair showed up at Focus. I decided to have AT fix them under warranty which was painless. It just cost me shipping to AT, return shipping was free. AT was great to deal with and turnaround was about a week. And thanks to whoever posted the deal, I forget who it was.
When I was finally able to listen to them for more than 5 minutes I found the clamping force waaay to strong. These are made for a small head. I have a big head like Tyll. So I bent the headband out a few times to the point that I could wear them for a few hours without any discomfort. They're very comfy now!
Another issue I had was terrible creaking coming from the joints. It was unbearable, every time I moved or opened my mouth the joints would creak, and it was so loud. I finally gave in and took them apart to grease all the joints. I feel alot of headphone manufacturers skip this important step. My Sony MDR1R's were the same, totally unbearable until I took them apart and greased them.
So finally I could sit down and listen to them without any discomfort or creaking, and they blew me away! They sound great. Lots of clarity, and I've heard some details in my music I've only heard with my nicer IEMs. I love the treble extension, this is probably the most important part for me. I love the airiness you get with good treble extension as long as it isn't too sibilant, and these haven't been too sibilant. The mids sound great, maybe a bit thin, but I like it. There isn't alot of bass but I think they do a good job of playing whatever bass is in the music. They sound alot like my EX1000 in that respect...they can go fairly low but they don't accentuate the bass. They sound very balanced and without any mid-bass bloat (I hate mid-bass bloat). The soundstage is decent, I can pinpoint cymbals etc. pretty easily, but the soundstage is a bit narrow (typical for a closed headphone I guess).
For reference, I've been using them with a CEntrance Dacport Slim with PC and straight out of my Sony Xperia Z1 phone. The other closed headphones I've used are MDR1R, ATH-A900X, K550, 553Pro, UE6000.
