If you don't mind headphones with a high clamping force, the Philips Fidelio X2HR ticks all those boxes.
Also, for some reason Philips doesn't sell the OEM pads as replacement parts (there are aftermarket pads, though).
I've used the HD 560S directly connected to both phone and laptop, and they are more than loud enough without an external amplifier.
Once, I was deliberately running them much louder than usual to test a set of musician's earplugs. Still didn't need an amp.
I also own a set. I really like how...
Received these as a Christmas present last year.

They fit comfortably despite my somewhat large ears and sound quite good for the price. The default sound profile is bass-heavy, but a companion app offers range of sound profiles...
The 600-ohm version requires more voltage than the 250-ohm version to reach the same volume. Bass tends to suffer the most when there is insufficient power or voltage, which is likely why the highs seem so much worse than your previous DT 990.
Since you already owned and liked the DT 990, you...
Part of the problem is that "neutral" means different things to different people. To some, it resembles the Harman curve; to others, the diffuse field target; to others still, "what the HD 600 sounds like".
Other than the elevated treble and deeper bass extension, the HD 560S does closely...
There are other well-known headphones targeting mixing/mastering use cases with deliberately bright treble.
The HD 560S is not nearly as bad as others in that regard.
Either would definitely be an upgrade in sound quality. Both will have less bass extension than the HD 206, but the 560S will be closer. Fit on your head is something you'll need to try yourself, but if the HD 206 fit well enough these should also work.
If good bass extension is a priority, get...
Both new? That would be a really good deal on the HD 600 (or possibly a bad one on the 560S).
The HD 560S has better bass extension, brighter treble, and is easier to drive without a dedicated headphone amp. The HD 600 is effectively a standard for "neutral" sound, has smoother treble than the...
There's another thread discussing the new headphones, including a link to measurements comparing them to the 560S.
At a glance, it looks very close to the 560S but with small tweaks at roughly 100 - 200 Hz, 4.5 kHz, and 6 - 8 kHz.
The Adorama article claims that "their excellent sound isolation system should kill any ambient noise in your listening environment".
Right after describing them as open-back headphones in the previous paragraph. :facepalm:
Other than the coiled cable and color scheme, there doesn't seem to be...
Clapping can create surprisingly loud impulses (the Guiness record is apparently 113 dBA). Your monitors won't be that loud in a small space.
They will be lacking in bass below about 80 Hz, but measure well in areas like step response and harmonic distortion. If you want measurement data, an...
The rear wall being covered with thick curtains and the desk being roughly centered along the wall helps. While not as good as proper acoustic panels, the curtains will cut down on reflections from higher frequencies. When positioning the speakers, don't point them squarely at the back wall -...
The 250-ohm version of the DT 880 would be easier to drive. I've used them plugged directly into a phone, and while I couldn't drive them to near maximum volume they would get loud enough to hear clearly.
