For me, they stay in place well. Although I don't have the MTW2, I had the MTW, and the fit was more comfortable long-term than the MW07 or MW07 Plus. That being said, the MTW did create more of a pressure-like seal, which itself can be fatiguing vs. the MW07 Plus that still seals, but rests in your ear (if that makes sense).
I do, however, enjoy the sound of the MW07 Plus much more than the MTW. When I had the original MW07 and MTW at the same time, I almost never reached for the MTW. I listen to mostly 80s arena rock/80s hard rock and it sounds really good on the MW07 Plus.
Sounds like you're not 100% sold on the MTW2, so it doesn't hurt to give something else a shot. Plus, the MW07 Plus look gorgeous and are on sale now.

I really like the matte black finish on this one:
