Any updates on this? My snapped today and there is no way to contact support regarding this issue. I can request service for $200 but I'd rather not if they will just break again in a year.
Seems like this is not an isolated incident after searching the forum or other sites: https://mspoweruser.com/microsoft-is-exchanging-surface-headphones-with-broken-band-but-no-admission-of-fault-yet/
