QuietComfort 45

Risky Buy$169.99
47% of 853 owners recommend
~1 in 6 failure rate — ~1 in 6 long-term owner reports describe a failure, most commonly audio output issues, Bluetooth problems, and microphone faults — typically appearing within the first 5 months. Of tracked warranty outcomes, 18 were resolved and 27 landed outside warranty coverage, so resolution is not guaranteed. 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.

Momentum 4

Buy If$279.95
60% of 1,298 owners recommend
~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.
