I was so underwhelmed by my Neumann KH120 studio monitors, I wouldn't consider their headphones.
The mics- TLM103 are great, thy're good- the U87 is great...
I had an M149 which is double the price of a u87- also underwhelmed by it.
On my list of headphones to get are I think Blue Sadies so I'd stay where you're at...
Although I've used Bose for comfort for years- my model of choice has been long discontinued... I got to tell you I'm super happy with my Sony MDR 7506.
I don't understand $500 headphones for home use when i've been in million dollar studios and at most they have $100-200 Sony MDR or Beyerdynamic headphones. I see $500+ headphones discussed on forums, and guitar groups, and recording groups, home studio stuff- but in every real studio- they've never had big dollar headphones.
