I have been on a decade-long quest to find a headphone that sounds good to my ear for both music listening and critical audio work. My requirements were that it: 1) does not have that giant, fatiguing treble spike that most headphones have - I prefer more of a "Harman" curve with somewhat reduced treble, 2) has good, flat-or-better low bass response, 3) has a smooth midrange, 4) is closed-back and 5) doesn't cost a fortune.
I finally found all of the above, first with the on-ear V-Moda M-80 (now discontinued). I use this now when listening to music around the house via Roon on my iPad. And still love it. Really smooth mids.
Figuring that I liked the "V-Moda sound", I tried the M-100 Master and that is now my reference over-the-ear closed-back headphone. Is it "perfect"? No. But, for whatever reason, these translate for me to/from my calibrated studio monitors well enough. And I didn't have to spend more than $250.00. I had heard the older M-100 previously but thought the bass was a bit too much. Now owned by Roland, they made some tweaks and that made the difference for me. And they are built like a tank with a nice quality (one-sided) cable. (another pet-peeve of mine are "strangulation" cables that attach to both ear cups.) They take EQ from Roon very well too.
Note that I also liked and own the Oppo PM-3, especially the clean articulation of the highs being planar. But the bass never sounded "right" to me, even with EQ. For digging out extra detail or looking for noises/issues, I still have my Sony MDR-7506 and some Beyers that have upper-mid and treble spikes respectively.
The M-100 is being fed by a Schiit Modi 3 / Magni Heresy combo in my recording/editing/mastering desktop rig.
There's my story and I'm sticking to it
