Noise-cancelling headphones: over-ear vs. earbuds, and what the generation number is worth

Where you'll wear them decides the form factor; the previous generation is usually the value pick.

Active noise cancelling (ANC) is excellent on the top three or four lines and mediocre below them; within the good lines, the differences are comfort, call quality and price.

Over-ear or earbuds

• Over-ear: best cancellation, best battery (30+ hours), comfortable for long flights, obvious to wear. Check clamp force and ear-cup depth if you wear glasses.
• Earbuds: good cancellation now, pocketable, fine for commutes and the gym. Battery is 5–8 hours per charge plus the case; fit decides everything, so look for multiple tip sizes.

What to check

• Multipoint (two devices connected at once) — laptop plus phone is the common case.
• Transparency mode quality — the good ones sound like not wearing headphones; cheap ones hiss.
• Call quality in wind and noise — the weak spot of most earbuds; reviews with recorded samples are worth finding.
• Wear detection, folding, a 3.5 mm jack for in-flight entertainment, and the case size.
• Codec support only if you know you need it; AAC and SBC cover phones and laptops.

Generations

Flagship lines refresh every two to three years. The outgoing model is typically 20–40% cheaper for a few months and loses little; the upgrade usually buys a slightly better microphone array and a redesigned case. Refurbished units from the manufacturer are a reasonable buy; third-party "renewed" listings are not the same thing.
