I like the cable, especially the length. Can watch movies with them on my couch which I couldn't do if it was shorter. Re the 650, it was interesting to listen to the 650 through 820 last week at the Sennheiser store. I had just come from an Orpheus session so the 650 sounded worse than I'd experienced before. Everything after it was so much better than the one before, to my ears anyway, with quite a jump going from the 660S to the 800. It made me glad I recently sold my 6XX and HE-4XX to buy the EditionXX.
