I'm curious what other people think are the best headphones for watching movies and why? Price is no object. If your answer depends on your amp, please list the amp as well.
I'd recommend the Bose AE2 because the comfort is unprecedented and I really don't notice a big difference in movie sound quality on most $100+ headphones (not that it's bad).
I also use the HD800's for my movie watching and PC gaming. The ambient noise, backgrounds, detail in busy scenes and all that make it a much more lifelike experience.
I think something like the DT880/AKG Q701 would be a good lower cost alternative for detail lovers in movie watching.
The Fostex TH900 also does pretty well if you want to feel the explosions and impacts of things like punches due to their bass response.
For me, we both watch movies on headphones so having the same headphone is preferred. For budget reasons, it's impractical for us to have two HD800s, but two DT 880 is doable. They're comfortable, too. If you have a way to use volume normalization (media players often have those options), I recommend to use settings that help bring out dialogue. Another low cost alternative are the Sennheiser HD239 - they're great and comfy, too.
