Your needs, this model
Does it fit your priorities?
Can I leave my phone and laptop connected at once?
Yes. Bose's guide allows up to two active Bluetooth connections and up to six devices in the stored list. Audio still comes from one device at a time: pause playback on one source and start it on the other. Multipoint is switching, not mixing.
Explore this need in the finder →Will the supplied 3.5 mm-source cable play if the headphones are switched off or out of battery?
Bose's Owner's Guide says the headphones must be powered on to use the included USB-C-to-3.5 mm cable. The manual supports USB-C audio while charging and instructs users with a depleted battery to connect USB-C external power, then power the headphones on. Do not count this as passive, battery-free analog playback.
Explore this need in the finder →Does the 24-hour ANC-on figure include Immersive Audio?
No. Bose's guide separates up to 24 hours with noise cancellation on and Immersive Audio off from up to 18 hours with both noise cancellation and Immersive Audio on. These are stated maximums under Bose's described conditions, not a promised duration for a particular listener or trip.

The 2026 QuietComfort Headphones (2nd Gen) are not just a color refresh of Bose’s earlier QuietComfort model. The documents describe a new USB-C audio route, Bose TrueSpatial and Cinema listening modes, updated Aware-mode ActiveSense, and changes to the physical design. For this review, the practical question is whether those extras fit your routine—and whether you need the newer digital/analog wired setup or the older model’s passive cable fallback. This is a source-based assessment, not a hands-on listening test or measurement.
Which configuration this review covers
Bose’s U.S. product page identifies the selected Black configuration as QC2G-HEADPHONEARN-BLK-WW. Bose introduced the model in August 2026; its support comparison distinguishes it from the original QuietComfort Headphones that remain a separately named product. Do not confuse either with QuietComfort Ultra Headphones (2nd Gen), which is a third model with different positioning and specifications. The feature analysis below is grounded in the Black unit and model 443644 Owner’s Guide. I also checked the six exact U.S. finish pages listed below: Bose gives them the same family product ID and name, the same 19 non-cable technical-specification values, and no separate functional capability. The pages do not, however, resolve whether every color package contains the analog cable; the conflicting variant-level fields are called out rather than treated as equivalent box contents.
Exact finish variants and the package-field conflict
The selected U.S. pages identify these finish-only siblings by separate variant codes. Each page’s “What’s in the box” list names the same headphones, carry case, 39-inch USB-C-to-USB-C cable, USB-C-to-3.5 mm cable, and safety sheet. The model 443644 guide also lists the analog cable. But Bose’s separate “Audio cable included” specification is not consistent across those selected pages: it says Yes for Black, White Smoke, and Eucalyptus Green, and No for Sky Pink, Rosewood Mauve, Dewdrop Mint, and Hazelnut Taupe. That is a real source conflict, not evidence that the latter four packages definitely omit the cable. Check the exact SKU and seller’s package listing if the analog lead matters; do not assume a color name settles it.
I found no other difference in Bose’s listed technical specification rows, and the pages point to one model family rather than separate hardware editions. The shared assessment therefore applies to their documented listening functions, while the cable-in-box question remains configuration-specific and unresolved. The product images below identify the manufacturer’s selected finish; screen color and lighting are not a promise of how a finish will look in person.

More control, not a guarantee of quiet
Bose documents Quiet, Aware, Immersion, Cinema, Off, and custom listening modes. Quiet is the full-cancellation setting. Aware lets outside sound through and can use ActiveSense to raise cancellation around sudden or persistent loud sounds. Immersion and Cinema pair Bose’s spatial processing with cancellation; Cinema is aimed at video and places dialogue forward. These describe available controls, not a measured ranking against other headphones or a promise that a particular fit will block a particular sound. Seal, source noise, volume, and the wearer’s preferences still matter.
Bose’s support page says the redesign uses pill-shaped earcups and a wider, smoother-sliding headband. The product page describes removable around-ear cushions and six microphones. Bose presents these as design and call-related features; no fit test was performed for this assessment. Glasses, hair, or hat interference should be treated as individual fit questions, not answered by the product copy alone.
Multipoint is two connections, one audio stream
The Owner’s Guide allows up to six saved devices and two active Bluetooth connections at a time. That suits a phone-and-computer routine where you want both devices paired and ready, but it does not mix two audio sources. To switch streams, pause the first device and start the second. Bose says calls may arrive from either connected device while one source is playing. You can manage multipoint in the Bose app; basic pairing can also be initiated from the device’s Bluetooth settings. Bose lists Bluetooth 5.4, but I did not find a primary U.S. codec list for this configuration, so codec compatibility is not assumed.
Read the runtime as a mode-specific maximum
Bose gives up to 24 hours with noise cancellation on and Immersive Audio off, and up to 18 hours with both noise cancellation and Immersive Audio on. A 15-minute charge is advertised for up to 2.5 hours under Bose’s stated conditions; full charging is listed at up to three hours. These are manufacturer figures, not a forecast for a specific trip, call pattern, firmware state, source device, volume, or aged battery. If a long journey is your use case, leave a margin rather than treating 24 hours as guaranteed seat time.
USB-C audio and an analog-source cable are different routes
USB-C is more than a charging connector on this generation: Bose describes digital audio input up to 24-bit/48 kHz from a compatible source, and the guide says the headset can play USB audio while charging. The manual also says a depleted headset can be powered from an external USB-C source for continued USB listening. That is useful for a compatible phone or computer, but it is not battery-free passive listening.
For a 3.5 mm source such as an aircraft seat jack, Bose lists a USB-C-to-3.5 mm cable. The Owner’s Guide requires the headphones to be powered on for cable playback; if the battery is depleted, connect external USB-C power and turn the headset on. In this analog-source mode, Bluetooth, calls through the headset, its microphone pickup, and headphone media controls are unavailable, so the source device handles playback. Bose does not publish a separate ANC-on runtime for this cable arrangement, so do not transfer the Bluetooth 24-hour rating to wired analog use or assume the headset mic remains available.
The cable question is variant-specific on Bose’s own pages, not just a generic Black-page discrepancy: the selected White Smoke and Eucalyptus Green pages, like Black, say “Audio cable included: Yes,” while Sky Pink, Rosewood Mauve, Dewdrop Mint, and Hazelnut Taupe say “No.” All six pages nevertheless include the cable in their visible box-contents list, as does the shared Owner’s Guide. With those contradictory statements, this assessment cannot guarantee what any particular retail package contains. Confirm the full suffix and the exact seller box contents before relying on the supplied cable.
Fit, charging, and everyday checks
Bose lists a carry case, a 39-inch USB-C-to-USB-C cable, the USB-C-to-3.5 mm cable, and a safety sheet; it says a power adapter is not included. The user guide warns against use near water, and the reviewed page does not supply an IP rating. Bose lists no headset-only weight in the source set used here. If that number, water resistance, or a particular replacement-cushion fit is essential, treat it as unresolved until you verify a model-specific manufacturer source rather than borrowing a figure from the Ultra or prior generation.
Who should shortlist it—and who should pause
The strongest evidence-backed fit is a listener who wants Bluetooth ANC with two devices connected, can use the 24-hour ANC-on maximum as a planning reference, or expects to use digital USB-C audio. The included analog-source route is also useful if you can keep the headset powered. Pause if battery-free cable playback is essential: Bose’s guide says this model must be on for cable audio. Also pause if your buying decision depends on a codec list, headset-only mass, analog ANC runtime, or a water-resistance rating not documented in the sources above. Before choosing a seller, confirm the exact Black model code, included cable configuration, source-device compatibility, and current return terms.
