The only scored support-service report is negative, describing a poor experience when seeking help for a charging-related problem. There is not enough data here to generalize beyond that case.
Pros: Sensors, Weight comfort
Cons: Warranty and support service, Ear-tip replacement
Support experiences after early failures were extremely poor in the two customer reports: both describe getting little useful help, including a disputed warranty and an unresolved serial-number issue.
Pros: Audio-video sync accuracy, Integrated microphone
Cons: Warranty and support service, Ear tip size options
