~1 in 3 failure rate — ~1 in 3 long-term owner reports mention a failure, with ear cushions and bluetooth connectivity the most cited components, typically appearing within the first 14 months. Of tracked warranty outcomes, 30 were resolved and 23 were unresolved — outcomes lean slightly toward resolution but a meaningful share lands outside coverage. That puts this headphone third-lowest in failure rate among the 10 wireless headphones we track, near the category baseline of 27% serious failures.

At 14% serious failure, this is well below the wireless headphone baseline of 27%, making it more reliable than most headphones we track.

Buy only if you prioritize all-day wearing comfort and effective noise cancellation over audio fidelity.

+ The single most cited strength — 155 mentions put all-day comfort well ahead of every other attribute.
