Got mine today - ran home at lunch to catch the delivery guy. Here are my 10 minutes worth of observations comparing my Q701 to these before I had to come back to work:
The ear pads are definitely memory foam, softer than the Q701 foam. The cover seems to be the same material but together they make for a bit more comfortable wear. I'm sure extended wear will confirm my first impression.
As you know the pads are not angled but I haven't had enough time to describe any differences in sound stage, etc.
I never really had a problem with the bumps in the headband, but now that I've put on a pair that don't have them I can tell you I definitely prefer the new band.
I listened to them with the same setup as my Q701. A laptop - Audiophilleo 2- Metrum Octave DAC - vintage Yamaha receiver. I'll try them with an Objective 2 this weekend.
They seemed a just tad bit louder even though on paper the specs are identical.
Brand new, out of the box they seem to have a bit more bass than my Q701. I don't know if it just seemed like more because they seem louder, or if in fact they do have more. I don't think it was because I "Wanted" them to have more. I had a pair of K702 before and comparing those to the Q701 I was expecting less from these and am pleasantly surprised.
Was the difference dramatic? No. And it's too early for me to make that judgment anyway. Right now I'd say you could probably EQ your way from a Q701 to what I heard from the anniversary edition.
More to come later this weekend. I left them playing when I came back to work.
