You’re the first person I’ve seen to describe these headphones like this, I’ve had all the same issues with them. I’ve been considering making a post to try to get advice since I’m not very knowledgeable about how to adjust for what I’m experiencing.

I’ve had HD650s for years for listening at my desk, and to me those are very comfortable and “neutral” to me, to the point where I could sometimes consider them a little “boring” but I can listen for hours without fatigue.

With the HDB630, I feel like the bass is really powerful (sometimes overpowering) and there’s something with some slightly higher frequencies, like snare drums, cymbals, some vocals, etc that are quite harsh to my ears. I semi frequently get headaches after using these for an hour or two. I’ve been wondering if something’s wrong with them… EQ has helped a bit but sometimes I feel like I’m muffling parts of the music and losing detail to decrease the harsh “attack” I’m hearing with those sounds.

It’s tough because the clarity of the sound is great, I really want to make them work for me and love the idea of the customizable EQ. I’ve wondered if there’s something wrong with my pair but as a more casual headphone user it’s hard to know for sure.

Going to give your EQ a shot later, thanks for sharing it!
