Other features
AptX
CMF Headphone ProNo score yet
Bose QuietComfort (2nd Gen)
1.6
aptX support is absent, which several reviewers see as a disappointing limitation for a premium wireless headphone, especially beside the Ultra's higher-resolution codec options.
Auto-play/wear detection
CMF Headphone ProNo score yet
Bose QuietComfort (2nd Gen)
1.0
The lack of head detection is a notable omission at this price, so the headphones do not automatically pause when removed.
Cable quality
CMF Headphone Pro
2.5
The included analog cable works, but one reviewer found it noticeably short. It is fine for nearby laptops and handheld devices, less ideal for setups that need more reach.

Channel matching
CMF Headphone Pro
2.0
Personalized tuning created an uneven left-channel result for one reviewer, making the presentation feel unbalanced. That reviewer preferred the sound with the personalized profile disabled.

Ecosystem integration
CMF Headphone Pro
3.0
Ecosystem integration is mostly good but not perfectly even. Some advanced functions may lean more heavily on Nothing OS or Android, so buyers outside that ecosystem may not get identical feature parity.

Find My
CMF Headphone Pro
3.5
Find My is basic rather than precision tracking. It can play a sound to help locate nearby headphones, but it does not provide AirTag-style directional finding.
Bose QuietComfort (2nd Gen)No score yet
Gaming preset EQ profiles
CMF Headphone Pro
2.5
Competitive gaming gets no dedicated sound-profile presets. The headphones can still game well through wired or low-latency modes, but there is little specialization for positional competitive play.

Hearing protection mode
CMF Headphone ProNo score yet
Bose QuietComfort (2nd Gen)
4.7
ActiveSense is well regarded for softening sudden loud sounds while Aware mode remains usable. Reviewers found it helpful with train screeches, streetcars, and other sharp noise spikes.
Imaging precision
CMF Headphone Pro
3.8
Imaging is competent rather than exceptional. Directional placement can be surprisingly clear on some tracks, but the overall precision remains below dedicated higher-end headphones.

Multi-platform compatibility
CMF Headphone Pro
4.5
The headphones work well across Android, iPhone, Windows, and wired sources. Reviewers appreciated the broad compatibility, although some advanced features are stronger on Android/Nothing devices.

Replaceable pads/headband
CMF Headphone Pro
3.0
The removable earpads are excellent, but the headband is not similarly replaceable. That asymmetry limits how far the modular repairability concept goes.

Streaming service integration
CMF Headphone ProNo score yet
Bose QuietComfort (2nd Gen)
4.5
Spotify shortcut support was viewed as a useful convenience, giving quick one-button access to playback from the headphones.
Performance
Audio-video sync accuracy
CMF Headphone Pro
4.7
Latency is well controlled for video and casual gaming, especially in wired or low-lag modes. Reviewers who tested sync found speech, effects, and on-screen action aligned closely enough for normal use.

Gaming performance
CMF Headphone Pro
4.0
Gaming performance is good for casual play, especially with the low-latency mode or a wired connection. Competitive gamers may still want lower latency and more specialized positional tuning.

Idle static noise
CMF Headphone ProNo score yet
Bose QuietComfort (2nd Gen)
5.0
A previous-generation ANC hiss was not noticeable to the CNET reviewer on this model, suggesting a clean idle noise floor in that test.
Sound leakage
CMF Headphone Pro
3.7
Sound leakage is inconsistent across the small number of direct tests. Two reviewers found it low, while one long-term user considered it a serious privacy problem in quiet shared spaces.
Bose QuietComfort (2nd Gen)No score yet
Ownership and support
Auto on/off reliability
CMF Headphone Pro
1.5
Automatic power behavior is limited. One reviewer specifically called out the lack of the hoped-for auto-off behavior as a notable feature omission.
Bose QuietComfort (2nd Gen)No score yet
Controls and connectivity
Bluetooth
CMF Headphone Pro
4.8
Bluetooth performance is one of the least troublesome parts of the experience. Pairing is quick, reconnection is dependable, and reviewers generally reported strong range with few dropouts.
Bose QuietComfort (2nd Gen)No score yet
Smart listening features
CMF Headphone Pro
4.4
The personalized hearing profile is one of the more successful smart features. Most reviewers found it useful or noticeably better balanced, although a few preferred the stock sound or experienced uneven results.
Bose QuietComfort (2nd Gen)No score yet
Voice assistant integration
CMF Headphone Pro
4.5
Voice-assistant access is easy to map and responsive when used. The customizable action button adds flexibility for people who actually want assistant shortcuts on the headphones.
