Bose QuietComfort Ultra Headphones (2nd Gen) vs soundcore Space 2: Which Should You Choose?

For noise control, Bose documents Quiet, Aware, Immersion, and Cinema listening modes with configurable favorites; Space 2 documents an NC-button toggle between ANC and Transparency and requires its app to turn ANC fully off. For analog listening, Bose includes a 3.5 mm-to-2.5 mm cable, while Space 2 gives an AUX setup sequence: connect while powered off, then turn it on. Space 2 says its multifunction and volume buttons do not work over AUX, while the NC button remains usable when powered on. Its FAQ conflicts on AUX calls, so wired microphone behavior remains unclear. Bose also documents USB-C digital audio for compatible devices; Space 2 USB-C audio support is unknown, not a confirmed absence. These are feature-fit observations, not tests of ANC or sound quality.

The buying question

Which listening-mode controls and wired setup fit your routine: Bose’s named modes and documented 3.5 mm-to-2.5 mm cable, or Space 2’s ANC/Transparency button and AUX instructions?

The models describe different listening-mode controls and analog-cable setup details. Bose also documents USB-C digital audio, while Space 2’s USB-C-audio support is unknown; that one-sided documentation should be verified if it matters.

Quick verdict

Choose Bose QuietComfort Ultra Headphones (2nd Gen), 890101-0100, Black if

  • You want Bose’s documented Quiet, Aware, Immersion, or Cinema listening-mode choices.
  • The included Bose 3.5 mm-to-2.5 mm cable matches your analog source, or Bose’s documented USB-C digital-audio route meets a requirement you have verified against the alternative.

Choose soundcore Space 2, D1402, Jet Black if

  • Space 2’s ANC/Transparency button and app-based ANC-off workflow fit the noise-control states you use.
  • Its documented AUX connect-while-off, then power-on sequence and AUX button limits work with your source and controls.

When the recommendation changes
  • Your source device lacks USB-C audio output or you mainly use an analog headphone jack.
  • You want ANC fully off from the headphones: Space 2 says ANC-off is set in the app, while Bose’s page documents Quiet/Aware/Immersion/Cinema modes but does not establish an equivalent full-off setting.

The differences that matter

Noise Control And Listening Mode Workflow

Bose QuietComfort Ultra Headphones (2nd Gen), 890101-0100, Black

Bose documents Quiet, Aware, Immersion, and Cinema listening modes, multifunction-button cycling, configurable favorites (up to 10 on-headphone), and optional ActiveSense in Aware Mode.[1]

soundcore Space 2, D1402, Jet Black

Space 2 powers on in ANC by default; the NC button toggles ANC/Transparency, and the app is required to turn ANC fully off.[2]

What this changes: The usable difference is control workflow and documented state selection, not comparative noise reduction.[1, 2]

The better fit depends on your priorities

Analog Cable Connection And Control Workflow

Bose QuietComfort Ultra Headphones (2nd Gen), 890101-0100, Black

Bose includes a 3.5 mm-to-2.5 mm audio cable. The product page does not describe button behavior while using that analog cable. Bose separately documents USB-C audio for compatible sources at 16-bit 44.1 or 48 kHz; this does not establish what Space 2 supports over USB-C.[1]

soundcore Space 2, D1402, Jet Black

Space 2 lists AUX input and says to connect its included audio cable while the headphones are powered off, then turn them on. In AUX mode, its multifunction and volume buttons do not work; the NC button remains usable when powered on. The FAQ conflicts on calls, saying calls are unsupported and also that AUX cables with integrated microphones are supported, so call/mic behavior remains unclear.[2]

What this changes: Check the source-device jack and the controls you expect to use over a cable. Bose specifies the included cable endpoints; Space 2 documents the AUX setup sequence and its control limits. Space 2 USB-C audio support and Bose analog-cable microphone behavior remain unknown.[1, 2]

The better fit depends on your priorities

Best for your routine

Listening-mode controls

The better fit depends on your priorities

Bose documents Quiet, Aware, Immersion, and Cinema modes with configurable favorites. Space 2 documents ANC/Transparency switching at the NC button and app-based ANC-off. Choose based on which documented states and controls you will use; this says nothing about comparative noise cancellation.

Analog AUX listening

The better fit depends on your priorities

Bose includes a 3.5 mm-to-2.5 mm cable; Space 2 documents an AUX connect-while-off, then power-on sequence and inactive multifunction/volume buttons in AUX. Check the source jack and controls you need. Wired-call behavior remains unresolved for Space 2 and unspecified for Bose’s analog cable.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

No dated offer comparison or adequate price history was assessed. Consider only current offers you verify and the specific features you expect to use; no buy-now or wait recommendation is made.

Current offers and adequate price history were not assessed, so no timing recommendation is made.

Limitations

  • No matched independent test establishes an ANC, sound-quality, comfort, call-quality, or battery-life winner between these exact models.
  • The Space 2 FAQ gives conflicting AUX-call guidance: it says calls are unsupported but also says AUX cables with integrated microphone functionality are supported. Bose’s page does not specify microphone behavior through its analog cable. Verify the exact cable and device behavior before relying on either for wired calls.
  • Bose documents USB-C digital audio for compatible sources; Space 2’s exact-model page does not establish USB-C audio support. Treat Space 2 support as unknown and verify it with soundcore if it is a deciding requirement. Bluetooth versions, codecs, and manufacturer battery-life figures are not treated as real-world quality or endurance results.

Questions shoppers ask

What do the included wired connections tell me?

Bose lists a 3.5 mm-to-2.5 mm audio cable in the box and separately documents USB-C digital audio at 16-bit, 44.1 or 48 kHz from compatible sources. Space 2 lists AUX input and says to connect its audio cable while powered off, then turn the headphones on. Space 2 USB-C audio support is unknown; check with soundcore if needed.

What should I expect when using Space 2 over AUX?

The soundcore FAQ says to connect its audio cable with the headphones off and then power them on. It says the multifunction and volume buttons do not work in AUX mode, while the NC button remains usable when powered on. Its call guidance conflicts: one statement says calls are unsupported, but another says AUX cables with integrated microphones are supported. The FAQ does not resolve whether the included cable or your setup carries calls.

How do their documented noise-control controls differ?

Bose lists Quiet, Aware, Immersion, and Cinema modes and lets you configure favorites in its app. Space 2 switches between ANC and Transparency using the NC button; its FAQ says ANC fully off is set in the app. These control descriptions do not establish which model cancels more noise.

Methodology and sources

The exact-model manufacturer pages were compared for listening-mode controls and analog cable setup. Bose also documents USB-C digital audio, but Space 2 USB-C support remains unknown. These manufacturer descriptions support conditional feature fit only; no matched ANC, sound, comfort, call, or battery test was conducted.

AI assistance organized the source notes; no physical testing or direct performance measurement was conducted.
