I'm curious about how manufacturers identify individual Bluetooth headsets and other consumer electronics during service or warranty inspections.

If two units of the same model look identical and don't have a visible serial number, how do service technicians distinguish one from another? Do they use an internal serial number, Bluetooth MAC address, firmware ID, or other unique hardware identifier? Can these identifiers be read using diagnostic software through the USB port?

I'd appreciate insights from electronics repair technicians or anyone with experience servicing these devices.

I'm curious about how OnePlus service centers identify individual Bullets Wireless Z2 ANC headsets. Is there a unique serial number, Bluetooth MAC address, or internal hardware ID for each unit? If there's no visible serial number on the headset, how do technicians verify that a specific headset matches its warranty record?

I'd appreciate any technical details about how the identification process works.
