That's perfect, I think if there was a subtle change to make, it'd been to make them a little bit less bright so I'd be happy.The older ones were just a bit brighter sounding, a bit too bright IMO.
The newer ones were less bright and needed less correction to sound good to me.
My 2024 pair will arrive in a day or two, found it for 130 with a coupon code from Sennheiser themselves, new.
I mainly mix now on a pair of ProAcs and Amphions, switching from Yamaha NS10m (1978) and KRKs.
That way my HD650 didn't correlate that well with what I achieved on the speakers anymore, even though I love them to bits, they sound comparatively now rather old.
I hope the 560s will do the trick so I don't have to try out the 490 Pro. Basically needed a more clear and responsive version of the 650s with a better low end.
