Oh my gosh! Sorry I didn’t reply to this sooner. It got lost in the shuffle somehow.
The 1000X M2 is still a big question mark because it’s only been out for a few weeks. The cracking problems on the original model didn’t show up in earnest till thousands of people used them regularly for a few months, so I can’t say exactly if the new one will have the issue or not. I haven’t tested a pair yet myself, and after this whole debacle, I’m skeptical.
I wish I had a better answer for you! It seems like the M2 adds very minor software additions to its noise-cancelling, and that not much has changed at all on the hardware side. But companies make material changes constantly without telling people. So we’ll just have to wait and see.
Sorry that my answer took forever and that it was kind of lame!
