660s is a fine machine. People often say headphone x is better because of random stat, or, headphone y is better value for money. Honestly can't do wrong with a 660s, beautiful all round quality headphone.

Not the end of the line for me.

Went from HiFiMAN Sundara, to Beyerdynamic DT1990 Pro, to Sennheiser HD 660 S. Tested all 3 with JDS Labs Atom Amp, Scarlett 2i2 1st Gen, & Tidal. The Sundara was insanely good all around and felt like it was made for my ears, both fit and sound. Bass was awesome thanks to planar tech. Unfortunately...

+1 for Oratory’s preset as a starting point. He explains how to adjust them to preference. Personally I felt the need to tone down both bass and treble, but I’m now very happy with the 660S.

Chrono Reviews the Sennheiser HD660s - A legend at a premium

That makes it a you know more natural sounding.

Solderdude at DYI audio heaven compared these headphones. The 660S was the worst measuring for some reason. Oh well, Senn just doing their weird thing ;)

Amazing headphones, the best I've ever used

I bought these as well as the Beyerdynamic DT 1990 Pro to compare the two. The latter lost, easily. The HD 660 S is incredible. No frequencies pop out like the Beyerdynamics (too harsh in the high end), everything is very even. Excellent in the mid-range for sure, unlike many headphones that try to ...

Also have the 660s. I place it on a curved wooden headphone stand so it's being mildly stretched all the time, helps a bit and it won't lose the grip. Awesome headphone, I honestly prefer vocals on this more than the 800s or arya.

Honestly, I have the AKG Q701 and it is one of the best headphones that also meets all of your criteria. I would also suggest the Sennheiser HD-660S and the Shure SRH-1840. Both are excellent choices!
