Just received mine. Couple quick observations. The pads look MUCH better. The stitching is great now and they are back to different pads for each ear. The woodies had the exact same pad on each and it simply looked stupid. The inside is also different. The new ones use perforated leather instead of the fabric mesh on the old one. No complaints about the wood veneer. Overall it looks like a quality headphone. Even the yokes look better (on my teak version the yokes had visible molding seams)
Box and cable are also much better. The foam setup is different and the headphones rest on their sides instead of the cups being flat. The box also seems a bit smaller?
Take this one with a grain of salt (I've had them for an hour), but the sound so far is indeed a bit different. To me bass was immediately less present. I suspect this could be completely because of the earpads, since I have been wearing mine pretty much 10 hours per day since I got them and they look a bit thinner\squished already. I will listen some more after work and play around with the pads to see if its all in my head. Now people don't panic this was 1h of extremely unscientific testing.
Very curious to read the other people's impressions though...
Edit: Added some pictures
Actually, the lighter bass body works in tandem with my impressions of the 560, I think the housing redesign had something to do with that ;) Personally, I prefer it, though many may not. Not that it was a bad thing, but the original 560 had a midrange that was a little thicker than I'd want it :p The more controlled bass helped that a bit :)
