CMF Headphone Pro VS JBL Tune 780NC

In terms of design, the CMF Headphone Pro and the JBL Tune 780NC are identical across every measured specification in this category. Both are over-ear headphones with a closed-back design, which means they provide passive sound isolation by fully enclosing the ear — a practical advantage for commuters or anyone in noisy environments compared to open-back alternatives.

Both models feature a detachable and tangle-free cable, which is a meaningful practical detail: a detachable cable means a damaged cable can be replaced without discarding the entire headset, extending the product's lifespan. Neither headphone offers any water resistance, so users should keep both away from rain or heavy sweat exposure. Neither is marketed toward children, confirming these are full-sized adult form-factor designs. Both deliver stereo sound via dual speakers, which is the standard expectation at this tier.

Given that every design specification is a perfect match between the two, this category results in a tie. No advantage can be assigned to either product based solely on the provided design data — buyers should look to other specification groups such as audio performance, noise cancellation, or battery life to differentiate between them.

Across every sound quality specification provided, the CMF Headphone Pro and the JBL Tune 780NC are perfectly matched. Both cover the full standard human hearing range of 20 Hz to 20,000 Hz, use a 40 mm driver unit, and support Active Noise Cancellation (ANC) alongside passive noise reduction — meaning both hardware isolation and electronic cancellation are at work to block out ambient sound.

The shared spatial audio support is worth highlighting: this feature processes sound to simulate a three-dimensional listening environment, which elevates the experience for movies, gaming, and certain music formats well beyond standard stereo. The absence of a neodymium magnet in both units is noted, though its real-world impact depends heavily on overall driver engineering — it simply cannot be used as a differentiator here given the data available.

With every measurable sound quality metric landing identically, this group is a clear tie. Neither headphone holds a provable acoustic edge over the other based on these specs alone. Prospective buyers will need to weigh factors outside this group — such as connectivity, battery, or price — to make their final call.

Battery life is where these two headphones finally diverge. Without ANC enabled, the CMF Headphone Pro delivers up to 100 hours of playback compared to 76 hours on the JBL Tune 780NC — a 24-hour gap that is substantial by any measure. For frequent travelers, remote workers, or anyone who charges infrequently, that extra endurance translates directly into fewer interruptions across multiple days of use.

Interestingly, the gap closes entirely once ANC is switched on: both headphones land at an identical 50 hours with noise cancellation active. This suggests the JBL's ANC circuitry is comparatively more power-efficient relative to its passive runtime, while the CMF's ANC draws more heavily on its larger reserve. Either way, 50 hours of ANC-on listening is a strong result for both.

All other power-related specs are identical — both charge via USB Type-C, include a battery indicator, and lack wireless charging. The CMF Headphone Pro takes a clear edge in this category, but only in the ANC-off scenario; users who keep ANC running at all times will find the two headphones evenly matched on endurance.

The codec support is where this category gets interesting. The CMF Headphone Pro carries LDAC and AAC, while the JBL Tune 780NC forgoes both in favor of Bluetooth LE Audio. LDAC is Sony's high-resolution wireless codec capable of transmitting up to three times the data of standard SBC, making it a meaningful advantage for users who stream lossless or hi-res audio from compatible sources. AAC adds further value for Apple device users seeking better-than-default wireless audio quality.

The JBL counters with the newer Bluetooth 6.0 versus the CMF's Bluetooth 5.4, paired with LE Audio support — a modern standard designed for improved efficiency and multi-stream audio. LE Audio is a forward-looking technology, but its real-world benefits are still dependent on compatible source devices becoming widespread. For most users today, LDAC delivers a more immediately tangible audio quality upgrade than LE Audio's current ecosystem maturity allows.

Both share identical range at 10 m, support fast pairing, and offer wireless plus wired connectivity — so those factors cancel out. On balance, the CMF Headphone Pro holds the edge here for users prioritizing present-day audio fidelity, thanks to LDAC. The JBL is the more future-proof choice on paper, but only if its LE Audio capabilities are actually leveraged by the user's devices.

The standout difference in this category is microphone count: the CMF Headphone Pro packs 10 microphones versus just 4 on the JBL Tune 780NC. More microphones generally allow for more sophisticated beamforming and noise isolation algorithms, which can meaningfully improve call clarity and ANC performance in real-world environments with variable background noise. For users who take frequent calls or participate in video meetings, this is a practically significant gap.

The CMF also includes an in-line control panel on the cable, which the JBL lacks. When using the headphones in wired mode, this gives CMF users quick access to playback and call controls without reaching for the earcup — a small but convenient ergonomic advantage. Both headphones otherwise offer on-device controls, ambient sound mode, noise-canceling microphones, and headset functionality, so those features are evenly matched.

Neither headphone includes a dedicated mute button, which is a notable omission for call-heavy users on both sides. Still, the CMF Headphone Pro takes a clear edge in this group — its considerably higher microphone array and the addition of in-line controls give it a more feature-complete package, particularly for anyone who regularly uses their headphones for communication.
