Choosing a different sound profile is easy. Knowing whether that profile tells the truth about a recording is harder. The Nothing Headphone (1) Pro puts that distinction on a physical Flat EQ switch, alongside wireless noise cancellation and two wired inputs. It is an appealing combination for someone who listens to music and edits the occasional video, but the switch alone is not sufficient evidence to retire a familiar reference headphone.
The strongest reason to consider the Pro is having those listening choices in one device. The weakest is assuming that a studio partnership, three drivers or a high sample-rate specification establishes neutral reproduction. Published reviewers disagree about the Flat EQ sound, and the available evidence leaves important questions about repeatable reference use unanswered.
For an owner of the original Headphone (1), this is a purchase that needs a specific job to justify it. For a new buyer, the deciding questions are whether USB listening and direct mode switching matter, whether the seal stays comfortable and stable, and whether carrying the substantial case is acceptable.
A switch between listening and judging a recording
The Pro's architecture divides work between three drivers in each cup: a 40mm bass driver, a smaller dynamic driver and a solid-state xMEMS treble unit. Those are verified design differences, not three separate guarantees of better sound. The crossover, tuning and fit still determine what reaches the listener. A larger feature list does not establish whether a quiet vocal sits correctly in a mix.
The more useful change is operational. Nothing's Flat EQ explanation says the switch selects its studio-oriented tuning and disables other equalization, spatial audio and transparency. That removes several variables when moving from enjoyment to assessment. It also means a listener should not expect the usual ambient-awareness setting to remain available in that mode.
The switch can make a repeatable habit easier: listen to an edit without the personalization used for leisure, then return to the preferred setting afterward. Our editorial inference is that this convenience is valuable even when the profile is not a calibrated reference. It does not settle accuracy, and it does not guarantee that someone else's speaker or headphone will reproduce the balance the same way.
Flat EQ has not earned unanimous trust
T3's Max Freeman-Mills liked Flat EQ after several weeks of listening and travel. TechRadar's Becky Scarrott, after two weeks including home use, flights and USB listening, found it warm and echo-like rather than convincing. These are materially different judgments about the feature that gives this review its central question.
The sensible response is to retain both observations. Different source chains, material, fit and listener preferences prevent this disagreement from becoming proof of a universal defect. Equally, choosing the favorable review would not prove the profile suitable for mixing. Neither subjective endorsement nor a studio's name replaces evidence of a repeatable response under the conditions in which an editor will use it.
A buyer doing consequential sound work should keep a known reference available and check decisions against it. Flat EQ may be useful for spotting how an edit changes when personalized processing is removed; it should earn trust through that comparison. If a device already gives dependable results, waiting for clearer measurement evidence is reasonable.
Choose the cable before the sample rate
The practical distinction is between wireless convenience, digital USB input and an analogue source. Nothing's wired specifications describe maximum supported formats and explicitly make them dependent on the source. These ceilings describe what can be accepted; they do not tell the reader that a recording becomes more detailed simply by selecting the largest number.
| Listening path | Documented support | Useful decision and limit |
|---|---|---|
| Bluetooth | SBC, AAC and LDAC for music; LC3 for broadcast audio only | Convenient daily listening; codec support depends on the source and is not a guarantee of editing latency. |
| USB-C audio | Up to 24-bit/192kHz | A digital listening path for a compatible source; confirm the actual device and application rather than assuming every USB-C connection behaves alike. |
| 3.5mm AUX | Up to 24-bit/96kHz; Flat EQ low-latency claim | An option for an analogue output; the published latency claim is conditional and is not an independently verified whole editing-system delay. |
There is an unresolved detail in the manufacturer's documentation. The product page advertises an AUX figure below 15ms with Flat EQ, while the support explanation says below 20ms. We use the less aggressive support figure. Its separate Bluetooth claim is tied to a Nothing phone with Game Mode, so it should not be generalized to an arbitrary laptop or phone.
For video work, check the connection that will actually be used before paying for the theoretical format ceiling. An application, source and audio route can change the experience. The sources used here do not establish comparable end-to-end USB latency, and the AUX claim does not describe every link in a recording or editing chain.
Noise control depends on an unbroken seal
SoundGuys' Christian Thomas reports 87.4% average total attenuation in ideal test-head conditions. His five-day supplied-unit review also describes a seal that changed with glasses and jaw movement. The laboratory result and the everyday qualification belong together; fit can determine how much of the measured isolation survives.
This percentage cannot be treated as equivalent to Nothing's advertised maximum of 46dB. One is an average from SoundGuys' test procedure; the other is a theoretical maximum from the manufacturer's laboratory. Converting them into a simple winner, or treating the maximum as the reduction at every frequency, would give the numbers a meaning they do not have.
TechRadar found manual High ANC effective and reported clear calls in its windy-seafront scenario. Those observations support trying the Pro for daily use, but do not guarantee the same result with a different fit or wind direction. Before committing, a useful fit check includes wearing the glasses normally used, talking and moving the jaw, not only sitting still for a brief audition.
The travel load is more than 327 grams
Nothing's specification sheet lists 327g for the headphones and 383.5g for the case. Together that is 710.5g before cables, by straightforward addition. The carrying decision therefore concerns a substantially larger load than the headphone weight alone suggests. For a desk listener this may be tolerable; for someone packing light, it is a recurring cost in space and mass.
Endurance needs a similarly specific reading. Nothing rates AAC playback at up to 68 hours without ANC and 30 with it; LDAC's respective figures are 53 and 28 hours. The 68-hour test used 50% volume, default features and 25°C. SoundGuys had not completed its standardized battery test when its review was published, so there is no matching measured endurance result in that source to replace the claim.
Treat these as planning estimates, with the listening mode stated, rather than proof of a particular number of working days. Noise cancellation, calls, volume and source choices complicate that conversion. IP52 also needs care: Nothing's footnote excludes rain, splashes, immersion and excessive sweat. This is weak grounds for choosing the Pro as a wet-weather or exercise headphone.
Keep the original, or take the lighter Sony?
What Hi-Fi?'s review of Headphone (1) documents the original's single 40mm, KEF-tuned design and physical controls. The Pro changes the driver arrangement and listening-mode proposition rather than introducing tactile operation for the first time. T3's direct comparison found the overall sonic step relatively modest. Existing owners should identify which new function is missing from their current setup.
SoundGuys also confirms that the Pro's parametric EQ allows center-frequency selection rather than the original's restricted ranges. That can matter to someone who deliberately adjusts tuning. It is a more concrete upgrade reason than expecting every familiar track to sound transformed, particularly for an owner already satisfied with the original.
The Sony WH-1000XM6 is a close alternative when daily travel takes precedence. Sony lists approximately 254g, and SoundGuys' Sony review supports its noise-control and call appeal while confirming that USB-C does not carry audio. It cannot replace the Pro's USB listening route. We do not rank their battery or ANC numbers across different test conditions.
Readers whose main question is moving sound around a compatible home system have a different priority again. Our Sonos Ace Ultra analysis of home audio handoff explains that separate decision. System integration should earn a place in the purchase question only when it is something the reader will actually use.
Give the switch a job at your editing desk
The Pro makes the clearest case as a flexible listening headphone whose special mode has a defined, limited role. It is less compelling as a replacement for equipment already trusted for critical balance decisions. Before buying, name the task the switch or USB input would solve and decide how that improvement will be checked.
Music listener who occasionally edits: consider it if wired digital listening and returning quickly to an unpersonalized profile solve a real inconvenience. Keep a second reference for important sound decisions.
Current Headphone (1) owner: keep the existing model unless the Flat EQ switch, expanded EQ adjustment or changed sound has a demonstrated use worth the purchase.
Frequent traveler: compare the lighter Sony and audition the fit; the Pro's case weight remains present even when its battery lasts through a trip.
Reader seeking a sole mixing reference: wait for stronger calibration evidence or retain a familiar reference rather than buying on the word “Flat.”
A charging accessory is not automatically necessary. Nothing specifies a 5V/1A or higher adapter and names its Power (45W) charger in the charging test. That documents a compatible companion, but does not mean the headphones require 45W. Check an existing suitable adapter first; there is no safely verified Amazon.com link for the exact companion in this article.

Nothing Headphone (1) Pro (White): The exact White model suits a listener who needs USB audio and a physical Flat EQ switch. Its heavy case and disputed reference tuning deserve consideration before using it for critical edits.
Sony WH-1000XM6 (Black): A close alternative for travel when lower headphone weight and effective ANC matter more than editing features. USB-C handles charging, not audio, so it cannot replace the Nothing's USB listening path.
