I received mine about a week ago now and have been listening to them exclusively and haven't had a chance to compare them directly with any of my other headphones yet but will this weekend. I would say I'm around the 15 hour mark with these and I have to say I'm really impressed, they remind me of my GH1 but with a larger soundstage and the transparency of my RS2e. But I will compare more directly later I just wanted to post some initial impressions about these and that if they sound this good with only 15 hours I can't wait for how they will sound in a 100. Also I need to add that I'm very impressed with the build quality on these, they are a joy to hold.
