I bought a set of brand new AirPods Pro 3 last Tuesday. Their default bluetooth name was set to "Tykke numse" which is Danish and semi-offensive but fun (ask Google Translate).
I bought them from a respected, electronics franchise called Power just across the street from where I work. I went back to my desk, open them and immediately connected to my phone using bluetooth. Everything worked fine, no issues at all. The AirPod box was sealed and the AirPods were wrapped in glued paper strips. I went back to the store and asked them to check the AirPods. They checked their systems carefully and concluded that the AirPods were brand new from the Apple factory and newer opened before.
The people at the store were baffled but we had a good laugh. Have anyone seen this before?
