A fair bit of that is likely brain burn-in too. They are a nice headphone with a bass bias.I recently bought the Meze 99 Classics as my first foray into hi-fi equipment after researching a ton on head-fi and other forums. Straight out of the box, they do have a lot of excessive mid-bass bloom, which apparently is due to the infamous pad issue. After further research, it seems like the new revised smaller pads by Meze might help to combat this. Since the smaller pads aren't available in my country, I bought them directly from their website and they are currently in-transit.
But yesterday, I realised an interesting thing. My Meze's are 15 days old, and I didn't expect them to sound a lot different after break-in, but they surprisingly do. Maybe it's just the pad becoming a tad softer due to regular use, but I'm noticing that the mid-bass bloom is relatively a lot lesser than before. The bass feels tighter, but the impact seems to be a bit duller at the same time.
I listen to a lot of bass-heavy tracks, and straight out of the box, when I listened to some dubstep, it felt like each kick was a bullet piercing through my chest. Now, the bass is there for sure, but it is a bit more controlled yet less impactful. Straight out of the box, I felt that the cans didn't handle rock (especially older recordings) really well as the bass guitar used to overpower the mix and drown out the bite from the electric guitar, but now it is back to the lead guitar being the centerpiece of the show.
I'm not sure if it's the pad becoming softer due to repeated use, or just simple mental and physical break-in, but they honestly sound much more neutral and controlled now, maybe closer to what Tyll from Innerfidelity might have heard. Anyway, I'm getting the smaller pads in a week or so, and I'll post any differences that I find.
I used these as my mobile headphones for three years. Ran just great off of a phone (LG V30).
