The bluetooth
~1 in 6 long-term reports mention a failure, most within the first 25 months. Bluetooth and firmware reboot-loop issues are the most cited components. Warranty resolution leans unresolved — the majority of reported cases landed outside warranty or went unresolved. That said, the NC700's 11% serious-failure rate is well below the 24% baseline for the 15 wireless headphones we track.

No single component dominates
~1 in 3 long-term owner reports describe a failure — primarily the power switch, Bluetooth connectivity, and battery — typically surfacing between 12 and 73 months in. Of tracked warranty outcomes, 89 were resolved and 69 were not, so results lean resolved but a meaningful share lands outside coverage. Failure rate is about typical for wireless headphones: the category baseline is 24% serious failures versus 25% here.
