Simon, I now use Beyerdynamic 770s. They are great. I also have the Sony 7506 which is good to wear when recording.
For mixing long periods, I use Alessandro open headphones. Your Grados were modified by Alessandro. Both are comfortable, neutral and clear.
See I've heard a
lot of good things about the 770's and practically nothing
bad, that's why I'm leaning towards those.
And absolutely, these Grados are incredibly comfortable and clear, though like everyone I'd appreciate just a little more bottom end.
Anyway, good to have a handful of nice cans in my line of work
