The Bose QuietComfort Ultra Headphones (2nd Gen) remain the noise-cancelling benchmark: class-leading ANC, 30-hour battery life, lossless USB-C audio, and all-day comfort. Sound is lively and bass-forward rather than neutral, and the $449 launch price stings — but frequent discounts make this the flagship to beat for travelers and commuters.
— THE VERDICT · JUDGEANY EDITORSWhy the 2nd Gen exists
Bose's QuietComfort Ultra Headphones (2nd Gen) arrived on October 2, 2025 at $449 with a short brief: fix the two things owners complained about most — short battery life and no wired lossless — without touching the design that already worked. The battery claim rises to 30 hours with ANC on (23 hours with Immersive Audio, 45 with ANC off), and USB-C now carries lossless audio instead of just charging. A new Cinema Mode joins the Immersive Audio lineup. This review aggregates manufacturer specs, published expert measurements, and owner impressions. We don't run a test lab; the scores below are editorial judgments built on that evidence.
Noise cancelling: still the benchmark, with one asterisk
No one disputes that these are among the very best noise cancellers money can buy. What Hi-Fi called them the absolute best active noise-cancelling cans for the money, and SoundGuys gave the 2nd Gen 5/5 in its October 1, 2025 review, praising how effectively it kills annoying real-world sounds — its reviewer even reported the first case of "eardrum suck" in 15 years of testing. The asterisk: SoundGuys' lab testing found gross noise attenuation nearly identical to the first generation, noting "there really isn't much of a difference here," despite Bose's claims of improved ANC. Bose's actual wording was "more precise" ANC, which suggests the gains are in how the system targets specific sounds rather than raw reduction. The conclusion still stands: the 2nd Gen starts from a baseline that was already class-leading, so even a marginal refinement keeps it at the top.
Sound: lively, bass-forward, better wired
SoundGuys' lab measurements show a 3–6 dB bass emphasis over its house curve — pleasant and punchy for most listeners, if a little dark — and its HEAD acoustics MDAQS score of 4.7 out of 5.0 predicts crowd-pleaser status. Expert Reviews praised the clear, detailed sound with deep bass and found call quality excellent on a busy London street. Not everyone agrees — Consumer Reports found the sound "somewhat bassy and grainy," with a midrange it called hazy and congested. Tom's Guide, for its part, felt the musical Immersive Audio modes thin out bass and detail, preferring plain stereo. Two upgrades are unambiguous: lossless audio over USB-C, and aptX Adaptive with Snapdragon Sound on Android. iPhone users are limited to AAC.
Comfort and battery: the honest strong suit
At 0.583 lb (264.4 g), the 2nd Gen stays one of the lightest flagships around, and comfort is the most consistently praised trait across reviews — What Hi-Fi calls it one of the most comfortable wireless over-ears for long wear. Bose rates battery life at 30 hours with ANC on; SoundGuys' standardized rundown measured 27 hours and 12 minutes, comfortably near the claim. A 15-minute quick charge adds about 3 hours, and you can now charge while listening. Caveats: SoundGuys notes heat buildup in summer and larger ears touching the inside of the padding, and there is no IP water-resistance rating, so rain and sweaty workouts are off the table.
Should Gen 1 owners upgrade?
Probably not at full price. SoundGuys' direct comparison found the 2nd Gen's tuning truer to its preference curve — the original had a harsh treble peak around 8 kHz — but its user poll suggested the first generation's microphone scored better. Trusted Reviews reached a similar verdict: the 2nd Gen has useful updates, but cheaper Bose options deliver slightly less ANC and sound for less money, making them the smarter buy for many. Android Authority reported the first Amazon discount, from $449 to $399, during Black Friday in November 2025, and street prices have kept dipping since. The 2nd Gen makes most sense for new buyers or anyone stepping up from an older Bose pair.
Who should buy it
Frequent flyers, commuters, and office workers who want the deepest noise cancellation available with all-day comfort should buy the 2nd Gen. Android users get the most from it thanks to aptX Adaptive and Snapdragon Sound. If you own the first generation and are happy, keep it. If the budget is tight, check the current price on Amazon — discounts are frequent — or look at Bose's cheaper QuietComfort line.
