I'm having them replaced for the 4th time. The Digital Crown or the ANC button keeps failing after 3-4 weeks. Minutes/hours before failing, they are behaving heretically, which is a common behavior of short circuits, and you can guess, caused by water damages.
Also, when waiting for a replacement, on top of having the crown failing, the automatic head detection broke.
I asked for a refund or gift card, but they said no so far. I took the AppleCare+ so I guess I'll get a fresh new pair every month for the next 2 years 🤷♂️
