Since I'm in the market for an earphone but too cheap to get the original, I went on and bought this from the seller.
Seller claim ANC is working but they're NOT.

I can see ANC is being enabled by default and you can turn it off or on, or turn on transparency mode. As far as I can tell, turning on ANC only seems to make the sound louder but NOT A REAL ANC. If you tried real one you'll hear a faint buzzing noise indicating ANC is on which means the chip trying to counter outside noise. This fake one does not have that. Although for my purpose it still works as a passive noise canceling.
Transparency mode is working and clear.

No, cannot update firmware. With original, Airpods Pro will have its own settings page in Settings ~ About and Accessibility menu (using with iphone/ipad). With this fake, it won't even available there. That's how you'll know if you have a fake.

It does comes with force sensor and gesture but NO active ANC.

Mine when checked shows the serials belongs to a replaced unit.

Cannot update firmware. Settings not available.

Single, double and triple tap works.

The only tap that DOESN'T WORK is tapping on the case to see charging level when charging wirelessly. Usually with the original, while charging on any Qi charger tap the case with your finger to make the light come on and see charging status. This fake doesn't have that.

Not sure if you're replying to me but just to clarify I'm just reviewing the unit as-is, as per my experience. Definitely not complaining as I'm volunteered to buy this on my own conscience fully understand that this is 1:1 copy. The ANC comment was to point out that sellers claim is untrue; in case people are looking to buy this based on those claim. As the user above me mentioned there are cheaper clone that does the same thing and have the same function.
