Pros: Comfort, great bass, even better treble, electronic master
Cons: cable is a bit too long
If you can get the th-600 for it's street price of less then $900 you did well. You give up some of the d7k fun for allot of th-600 refinement. Mids are faster and not as recessed as d7k. Bass hits a little less hard than the d7k, but the bass is cleaner and more controlled. The treble is less peaky and harsh than the d7k. If you liked the d7k back in the day then you will love the th-600 today. Are they worth the $1299 retail, no. But like the d7k there are lots of street price deals, some below $800 now. The review I'm giving is based off the $850 deal I got off PJ back in late july/ early august.
