MDR-1000X has been my best purchase, I had the QC35 and gave them to family.
10 hours extra for the new Sony seems like a good improvement but not enough to upgrade from gen 1. No interest in google assistant or siri.
I'd like the WF-1000X if if it had at least 8 hours battery, water resistance 56 or 67 ideally, and without the signal issues that even airpods have for me to buy into that form factor. The sound quality and lack of isolation is too much of a compromise for me. I must say I'm surprised the airpods have become so prevalent. The earpods came with the iPhone so that wasn't a surprise.
