Bottom Line

Choose for near-silent travel and a feather-light feel with handy USB-C wired audio; Skip if you want a truly premium build or a deep EQ app.

Best for

Frequent flyers and commuters who want the strongest possible noise cancelation and a comfort-first fit, plus the option to plug in via USB-C for wired listening and charging.

Not for

Listeners who demand a premium, all-metal feel, a deep multi-band EQ, or an IP rating for sweaty workouts and bad weather.

Verdict

Across reviews, the QuietComfort Ultra (2nd Gen) earns its flagship status with class-leading noise cancelation, a light fit you can wear for hours, and a genuinely useful USB-C audio mode for cleaner, lower-latency wired listening. The sound leans consumer-friendly with strong bass and a wide stage; with CustomTune plus a little EQ, many find it balanced and engaging, though detail fanatics may still prefer rivals. The biggest tradeoff is value and control: build materials feel plasticky for $449 and the app EQ remains a basic 3-band slider. If you prioritize travel comfort and silence over tweaky audiophile tuning, it’s an easy pick.

  • 4.1
    based on 3 reviews

    based on 9 reviews

    based on 14 reviews
    Sound quality: 4.1, based on 14 reviews
    Across reviews, the sound is described as enjoyable and travel-friendly, with a consumer-leaning tuning and strong bass; several reviewers say it improves on Gen 1, but a few still find it only fine or a bit dark versus audiophile-leaning rivals.

  • 4.0
    based on 4 reviews
    Microphone noise reduction: 4.0, based on 4 reviews
    Noise reduction on calls is usually effective, keeping background sounds lower while preserving speech, though some tests still let intermittent noise bleed through or add a slightly processed character.
  • 4.0
    based on 1 review
    Hinge durability: 4.0, based on 1 review
    Where mentioned, the metal headband/hinge structure is viewed as reassuring, even though much of the exterior uses plastic to save weight.

    Voice assistant access is supported via shortcuts or touch-and-hold actions in the app, making it easy to trigger assistants without pulling out your phone.
  • 4.0
    based on 4 reviews
    Noise isolation (passive): 4.0, based on 4 reviews
    Passive isolation benefits from a good seal and deep cups, but a few reviewers note the foam is not the thickest; overall, it helps the ANC work even better on commutes.
  • 3.9
    based on 7 reviews
    Microphone quality for calls: 3.9, based on 7 reviews
    Call quality is generally good for a premium ANC headphone, with most reviewers saying voices stay intelligible in noisy places; a few describe it as merely fine, compressed, or not exceptional.
  • 3.9
    based on 2 reviews
    Stability: 3.9, based on 2 reviews

  • 3.7
    based on 10 reviews
    Treble clarity: 3.7, based on 10 reviews

  • 3.7
    based on 5 reviews
    Frequency response accuracy: 3.7, based on 5 reviews
    Tonality can be shaped into a more balanced response with CustomTune and light EQ, but out of the box many characterize it as a V-shaped or slightly dark consumer tuning rather than strictly neutral.

    based on 9 reviews

  • 3.7
    based on 11 reviews
    App: 3.7, based on 11 reviews
    The companion app is generally stable and straightforward for modes, ANC, immersive audio, and device management, but many reviewers describe it as basic compared with feature-rich competitors.
  • 3.6
    based on 9 reviews
    Build quality: 3.6, based on 9 reviews
    Build quality is generally seen as durable enough for daily travel, but the heavy use of plastic and occasional rattly feel reduce the perceived premium value at this price.
  • 3.6
    based on 10 reviews
    Button control usability: 3.6, based on 10 reviews
    Physical buttons are serviceable but frequently criticized for doing too many functions (pairing/power, multi-press combos) and offering limited customization.
  • 3.5
    based on 1 review
    Cable quality: 3.5, based on 1 review
    Several reviewers mention the 2.5mm analog input as less common than 3.5mm, but the included cable and USB-C option make it easy to stay connected when needed.

Cons

  • 3.4
    based on 10 reviews

    The touch volume control is divisive: some find it responsive and sleek, while others call it imprecise or too easy to trigger large volume changes, especially without tactile feedback.
  • 3.2
    based on 1 review
    Ear cup swivel/rotation range: 3.2, based on 1 review
    The yoke/rotation design allows the cups to lay flat, but at least one review notes the rotation range is limited in one direction.
  • 3.1
    based on 2 reviews
    Smudge resistance: 3.1, based on 2 reviews
    Glossy accents look more premium to some, but multiple reviewers mention they pick up fingerprints and dust more easily than matte finishes.
  • 3.1
    based on 5 reviews
    Preset EQ profile quality: 3.1, based on 5 reviews
    Preset EQ or mode profiles exist and can help (e.g., bass-reducing or treble-boosting options), but many reviewers find the presets and overall EQ ecosystem underwhelming.
  • 2.9
    based on 11 reviews
    Equalizer customization: 2.9, based on 11 reviews
    EQ control is repeatedly called out as limited (a simple 3-band slider), good for small tweaks but not ideal for listeners who want granular tuning.
  • 1.0
    based on 5 reviews
    Water/sweat resistance rating: 1.0, based on 5 reviews
    Multiple reviews emphasize there is no official water or sweat rating, making these a poor choice for rain, heavy workouts, or sweaty gym sessions.

    Dongle: 1.0, based on 1 review
    At least one reviewer notes there is no dedicated low-latency wireless dongle, limiting plug-and-play latency solutions for gaming compared with some rivals.

FAQ

Is the ANC actually better than the 1st-gen QC Ultra?

Most reviewers describe Gen 2 as an iterative improvement: still top-tier, with slightly better precision, fewer quirks like hiss, and strong performance against sudden or higher-pitched noises.

How long does the battery last?

Real-world and lab-style tests commonly land around 27–30 hours with ANC on. Using immersive modes reduces runtime, while turning ANC off can extend it significantly depending on settings.

What’s the benefit of USB-C audio?

USB-C adds wired, lossless/hi-res playback while charging, and several reviewers note clearer sound and lower latency versus Bluetooth for video or desk use.

Is the app EQ good?

It’s widely described as limited: a basic 3-band EQ with a few presets. It can help tame bass or add treble, but it’s not ideal for granular tuning.

Are these good for the gym?

They have no official water/sweat rating, and fit stability is best for light movement. Some reviewers recommend using them mainly for travel, office, and home rather than sweaty workouts.
