As I'm getting quit paranoid about the manager complaining about the sound in the new apartment I moved into, it looks like I'm going to be relying more on headphones then ever to listen to DVD's, TV & CD's through my Denon 3801 system. I current have a Sennheiser HD-555 but based on the reviews I am currently planning to get the Sennheiser HD-600 which retails for $550 or so but I can get used/refurbished for $200 on Amazon.com. I originally was going to go for the Sennheiser HD-650 but one of the reviews I read said the 600 was much better.

Anyone have any recommendations? Any other brands & models to consider. Price right now is not a factor, quality is my factor. Any help appreciated. Thank You,
