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.
