Same here. The 2's seem to have had improved noise-cancellation (meaning, more effective) but in places like the subway, I also got a vaguely queasy feeling and would turn it off intermittently. Will be interested to see if anything changes with the update.Curious if anyone has had issues with the ANC in the airpods pro 2's in general since they got them. I can only compare them to my old beats studios but when I have ANC on while on the subway they make me feel nauseous and a bit of a headache. The beats when I first got them used to give me headaches after awhile but don't recall getting the nauseous feeling.
