I am having s new pair of HD-600s delivered tomorrrow. What is the expected break-in time?
Thanks so much for a great forum. I "love what I hear".

I dont believe in Break In, but i would say just run Pink Noise over nite.

It depends on your brain. If your previous headphone had a similar sound signature then they will sound good out of box. I think that Sennheiser makes a good quality headphones so hopefully they won't degrade in sound too quickly.

I give almost everything 100 hours of music and pink noise (http://simplynoise.com/). Bach's cello suites are a good choice.

No burning time for me. Specifically, Sennheiser said that their products need no burn in, ask them via e-mail if needed.
