~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.

Momentum 4

Buy If$279.95

~1 in 3 failure rate — Roughly 1 in 3 long-term owner reports mention a failure — but note that failure_measurable is false here: there are too few confirmed long-term owners to compute a reliable rate, so treat that fraction cautiously. Reported components include power button, connectivity, and battery issues, with onset typically within the first year. Warranty resolution leans unresolved (47 cases unresolved vs. 38 resolved), so failures often land outside coverage. Serious failure reports sit at 27%, about typical for wireless headphones in our tracking pool.

Buy it if you prioritize sound quality and battery life above bulletproof hardware reliability.

+ Repeatedly mentioned as the reason owners recommend it — a reference-class sound signature across genres.

− A vocal minority flags hardware failures — power button, connectivity, and battery issues appear across reports.
