Told myself I wouldn't get the Gen 2, but could not resist at least checking them out. Still quite unsure whether or not to keep and replace my Gen 1. My very quick initial impressions:

• Gen 2 feel slightly softer and with even lower clamping force already straight out of the box (even though I had no complaints on Gen 1). They really are super comfortable (still).

• Gen 2 has noticeably less hiss/white noise during ANC mode. There is some hiss during the first few seconds, but then for me it goes down to an (almost?) imperceptible level.

• ANC I just tested around the house so far and struggled to find any clear differences. They might be there, sure, but at least not immediately apparent.

• With Gen 2 you can now turn ANC on/off and set ANC strength from 1-10

• Sound quality I could not discern any noticeable differences (disregarding the cinematic mode)

• Microphones/call quality I did not test yet

• Gen 2 sand color is gorgeous, but I am quite partial to the darker sandstone tone of Gen 1

• They are really very similar headphones (well, obviously), this is nowhere near the XM5 -> XM6

So absent any call testing (where I am hoping they will have improved), imo the most noticeable upgrades are on ANC customization and the hiss reduction, otherwise not a WOW!-impact upgrade.

EDIT:

• Also, I have not been able to reproduce the thumping/popping sound with stronger movements on Gen 2, but I really wouldn't want to give any guarantees it is fixed. Just did some very brief tests indoors.
