That must sound really nice and relaxing with HD650.
Yes, that's the point.
Alright, someone sell me on HD 650s as a current HD 598 and HD 800 Sonarworks owner, and enjoying HE-500, LCD-2.2 (best of the bunch) and LCD-3 pre-fazor (not so much) in the past.
HD650 has an entirely different signature, maybe close to LCD - 2.2, maybe, but it's something of it's own. You can read my review on them if you're looking for an in-depth explanation.
new ones are easy to find and used ones are also easy to find
