Bose Bose QuietComfort Ultra Headphones (2nd Gen)

The lightest flagship here at 250 g and still the comfort benchmark, with USB-C lossless audio and a 3.5 mm socket. But SoundGuys found the claimed ANC improvement did not show up in measurement.

Review

What this product is

Written after the analysis, from the same sources the score is built on: the manufacturer's documentation, available studies and verified owner feedback.

The comfort choice, and the one to buy if you want both wired options.

SoundGuys measured peak attenuation of 50.0 dB at 15,400 Hz with an ANC score of 8.7/10 that beats 90% of over-ears — matching the Sony's score — and isolation at 7.1/10. At 250 g it is the lightest headphone in this ranking, which over an eight-hour flight is worth more than a decibel or two.

The honest caveat is Bose's own claim. SoundGuys' verdict on the second generation: "Despite Bose's claims that they've improved ANC, it doesn't seem to be the case in terms of gross noise attenuation." This is an incremental refresh, and if you own the first generation there is little reason to upgrade.

Connectivity is the best here for home listening. Both USB-C audio (lossless, 16-bit 44.1/48 kHz) and a 3.5 mm socket — the Sony lacks USB-C audio, the Sonos Ace and AirPods Max lack a 3.5 mm socket. Codecs cover SBC, AAC and the aptX Adaptive family including aptX Lossless, under Snapdragon Sound branding.

The battery figures need care. Bose Germany claims 30 hours in Quiet or Aware mode, and 23 hours with 360-degree spatial audio active. SoundGuys measured 27 hours 12 minutes against a 24-hour claim in the mode they tested. Both are plausible; they are not the same measurement.

Default tuning carries roughly 3–6 dB of bass emphasis with extension to 20 kHz, though SoundGuys notes the 3–8 kHz midrange varies substantially between fits — which is another way of saying the seal matters.

No IP rating. €379.95 RRP, €309.98 street.

Component scores

Where the score
comes from.

Four components, equal weight, each on a 0–10 scale and each resting on a named source. The overall score is their mean — the full procedure is in the methodology.

  1. Composition and specification9.0

    Declared composition and specification: active ingredients and their concentrations, energy classes, standards, technical parameters — and what the manufacturer leaves unsaid.

  2. Evidence and studies9.0

    Verification of the manufacturer's claims against outside sources: laboratory reports, industry testing, safety data sheets, certificates and regulatory decisions.

  3. Owner feedback9.3

    Analysis of verified reviews written after extended use, together with recurring fault reports for the model or series.

  4. Cost and value8.6

    Price set against what the product actually delivers, plus costs incurred later — consumables, energy, servicing, subscriptions — over the lifespan typical for the category.

FAQ

Frequently asked questions

Should I upgrade from the first-generation QuietComfort Ultra?

Probably not. SoundGuys tested both and concluded that despite Bose's claims of improved ANC, gross noise attenuation had not measurably changed. This is a refresh rather than a new product. If your current pair works, the money is better spent elsewhere.

Why does USB-C audio matter if it has a 3.5 mm socket?

USB-C carries a digital signal, so the headphone's own DAC handles conversion — giving lossless 16-bit 44.1/48 kHz from a laptop or phone with no analogue stage in between. The 3.5 mm socket matters for a different reason: aircraft entertainment systems, older equipment, and listening with the headphone powered off. Having both is genuinely useful, and only this and the B&W Px7 S3 offer it here.
