So I gave up trying to have a “universal” setting at the computer, and control the EQ in the headphones. Instead, I’ve now set the headphones to no EQ, and I’m using the PEQ in iTunes with some settings I found for “clear and balanced sound”, along with the recommendation to boost the 4K range for the Momentum 3, and I still miss the dynamics of other headphones, but the sound is MUCH better and faithful to the recording. Also, seems to fit several genres without much tinkering. Named it “Sennheiser”, and called it a day…

Awesome. I’ll try that. Thanks for the req.

Thanks for the info. It does sound really good for a car stereo.
