CMF Headphone Pro VS Nothing Headphone 1

Both the CMF Headphone Pro and the Nothing Headphone 1 share the same fundamental design philosophy: over-ear, closed-back headphones with a detachable, tangle-free cable and an included travel bag. For everyday commuters or home listeners, these shared traits mean a broadly similar ownership experience — portable, practical, and ready for transport out of the box.

Where the two diverge meaningfully is in weight and environmental protection. The CMF tips the scales at 283 g versus the Nothing's 329 g — a 46 g difference that, over hours of wear, can noticeably reduce fatigue during long listening sessions. On the other hand, the Nothing Headphone 1 holds a clear advantage in durability: its IP52 rating provides certified protection against both dust ingress and light water splashes, and it is explicitly rated as sweat resistant. The CMF's IPX2 rating offers only minimal drip protection with no dust resistance, making it more vulnerable in active or outdoor use scenarios.

In summary, the CMF Headphone Pro has the edge in wearability thanks to its lighter build, while the Nothing Headphone 1 wins on ruggedness with its superior IP52 rating and sweat resistance — making it the stronger choice for users who plan to use their headphones during workouts or in unpredictable environments.

At the hardware level, these two headphones are nearly identical in their sound engineering foundations: both use 40 mm drivers, share the same 20 Hz lower frequency floor, and offer ANC, passive noise reduction, and spatial audio support. For the vast majority of listeners, this common ground means a comparable baseline listening experience across vocals, bass, and midrange detail.

The single but notable differentiator is the upper frequency ceiling. The CMF Headphone Pro tops out at a standard 20,000 Hz, which covers the full range of human hearing. The Nothing Headphone 1 extends to 40,000 Hz — well into the ultrasonic range. In practice, no human can perceive frequencies above roughly 20 kHz, so this distinction has no direct audible benefit for typical music listening. However, it can indicate a driver tuned with greater headroom, which may contribute to a cleaner, less strained reproduction at the upper limits of audible frequencies.

Overall, the sound quality specs here are largely a tie for real-world use. The Nothing Headphone 1 holds a marginal technical edge on paper with its extended high-frequency range, but the CMF Headphone Pro matches it on every practically meaningful spec — making the audible difference between the two, based solely on this data, negligible for most listeners.

Battery longevity is where the CMF Headphone Pro pulls ahead decisively. It delivers up to 100 hours of playback and 50 hours with ANC active, compared to the Nothing Headphone 1's 80 hours and 35 hours respectively. That gap is significant in practice — the CMF can last through an entire long-haul travel week without a charge, and even its ANC endurance comfortably outlasts the Nothing's standard playback figure.

The interesting twist lies in battery capacity. The Nothing Headphone 1 packs a larger 1040 mAh cell versus the CMF's 720 mAh, yet achieves fewer hours of use. This suggests the CMF is simply more power-efficient — squeezing more runtime out of a smaller battery, which is a meaningful engineering achievement. Both headphones share identical charge times of 2 hours and use USB Type-C, so the charging experience is equivalent on both sides.

The CMF Headphone Pro wins this category outright. Its superior rated runtime — especially under ANC — makes it the stronger choice for frequent travelers or users who dislike reaching for a cable. The Nothing Headphone 1 offers respectable endurance, but cannot match the CMF's efficiency-driven stamina.

Connectivity is the closest contest of this entire comparison. Both headphones support wireless and wired use, share a 10 m Bluetooth range, offer fast pairing, and carry the same codec support: LDAC for high-resolution wireless audio and AAC for Apple device compatibility. LDAC in particular is the standout shared feature — it transmits at up to three times the bitrate of standard SBC, making it a meaningful advantage for listeners streaming lossless or high-bitrate audio on compatible sources.

The only measurable difference here is the Bluetooth version: the CMF Headphone Pro runs on Bluetooth 5.4 while the Nothing Headphone 1 uses 5.3. In practical terms, 5.4 introduces improvements in connection efficiency and low-energy communication, though the real-world impact for typical headphone use — at identical maximum ranges — is subtle rather than transformative.

This category is effectively a near-tie, with the CMF holding a marginal technical edge from its newer Bluetooth version. Codec support, which tends to matter far more to audio quality and latency in daily use, is identical across both headphones. Users prioritizing wireless audio fidelity will find no difference between the two based on these specs alone.

Two specs cut through the noise here and tell the real story of how these headphones differ in day-to-day use. The CMF Headphone Pro fields an impressive 10 microphones versus the Nothing Headphone 1's 6 — a gap that, in headphone design, typically translates to more sophisticated ANC processing and cleaner call quality, since more mics allow the device to better isolate voice from ambient noise and improve beamforming accuracy.

Flipping the advantage, the Nothing Headphone 1 includes in/on-ear detection — a convenience feature the CMF lacks entirely. This allows the headphones to automatically pause playback when removed and resume when worn again, a genuinely useful quality-of-life addition for users who frequently take their headphones on and off. The CMF compensates with an in-line control panel on the cable, giving wired users physical controls without reaching for the headphones themselves — a feature the Nothing omits.

On balance, the CMF Headphone Pro holds the edge for users who prioritize call performance and wired convenience, while the Nothing Headphone 1 suits those who value smart wear-detection for a more seamless listening experience. Neither dominates outright, but the CMF's microphone count advantage carries more weight for hybrid work or call-heavy users.
