Nothing X App Explained: 12 Settings Every Nothing and CMF Earbud Owner Should Know
Buying a good pair of Nothing or CMF earbuds is only half the experience. The…

Wireless earbuds have become predictable.
Most brands compete through better Active Noise Cancellation (ANC), stronger bass, longer battery life and slightly smaller charging cases. Those improvements matter, but the basic experience has changed very little: connect the earbuds, play audio and control it from your phone.
Nothing is trying something different with the new Ear (3a).
Alongside a larger 12 mm driver, improved noise cancellation and Nothing’s colourful transparent-inspired design, Ear (3a) introduces Audio Snapshot—a feature designed to work almost like a screenshot for sound.
Hear an interesting part of a podcast? Capture it.
Miss the beginning of an important statement? Ear (3a) can potentially include audio from before you pressed the control.
Want to record a supported phone or online call for legitimate note-taking? The earbuds can handle that too, subject to regional availability and recording laws.
That makes Ear (3a) considerably more interesting than another inexpensive pair of Nothing earbuds.
H View has not personally tested Ear (3a), so this is a researched launch analysis based on Nothing’s current product, support and community information.
Ear (3a) is the latest evolution of Nothing’s more accessible (a) series earbuds.
Nothing launched it globally on 7 July 2026 in four colours:
Global launch pricing was announced at $99 / £99 / €99. Nothing’s UK product page currently lists Ear (3a) at £99.
The earbuds combine:
But Audio Snapshot is clearly the feature that makes this generation different.
Imagine listening to an interview and suddenly hearing an important quote.
Normally you might rewind the podcast, pause it, find the timestamp and perhaps write the sentence somewhere else.
Ear (3a) attempts to shorten that process.
Nothing describes Audio Snapshot as essentially a screenshot for audio. While listening to music, video, podcasts or other supported media, the user can trigger a capture directly from the earbuds.
Nothing says Ear (3a) contains 32 MB of built-in flash storage, allowing recording to start from the earbuds before the captured audio is synchronised to the Nothing X application.
The most interesting part is pre-buffering.
Audio Snapshot can capture up to one minute, including as much as 30 seconds of audio that played before you triggered the capture, depending on the selected recording mechanism.
That means you do not always need to know in advance that something important is about to be said.
Nothing’s current support instructions say Audio Snapshot and Call Recording use a similar physical interaction.
While media is playing, pressing both earbuds simultaneously starts the Snapshot process. The recording stops automatically once the configured duration has been reached, so it does not require another manual stop command for a normal Snapshot.
Different capture modes can be configured through the Nothing X app, determining whether the Snapshot includes audio before and/or after the moment it was triggered.
This is exactly the kind of feature that deserves its own H View tutorial later.
Captured recordings synchronise with the Nothing X application.
Nothing says users can then:
This potentially makes Audio Snapshot much more useful for spoken content than music.
Consider someone listening to a two-hour podcast. Instead of saving the whole episode and manually remembering where an interesting discussion appeared, they can capture only the relevant section and later search or review its transcript.
That could be valuable for students, journalists, researchers, creators and professionals.
Nothing also provides a Nothing X Pro transcription model.
The company says the Pro model uploads recorded speech for cloud-based AI processing and converts it into searchable text. Because the processing happens through cloud AI models, an internet connection is required.
This creates both an opportunity and an important consideration.
AI transcription can make long recordings much easier to review, but users should understand that cloud processing may be involved before uploading sensitive business meetings, private conversations or confidential information.
Accuracy should also be verified when names, technical terminology, numbers or important instructions are involved.
Ear (3a) can also record supported calls.
Nothing says Call Recording can work when the earbuds are operating through an active Bluetooth calling profile, including traditional phone calls and supported services such as WhatsApp calls, Zoom and Google Meet.
A user can begin and stop a recording using the earbuds rather than reaching for the phone.
The resulting recording can then be transferred into Nothing X for playback, editing and supported transcription features.
However, there is an important restriction.
Nothing states that call recording is available only in selected regions because laws differ. The company also tells users to inform participants and comply with local privacy and recording laws. An audio notification may be played to other participants when recording begins.
This is the correct approach. Recording technology should never be treated as permission to secretly record other people.
Audio Snapshot may get the attention, but Nothing has also upgraded the audio hardware.
Ear (3a) uses a 12 mm dynamic driver. Nothing claims it produces up to 5 dB more bass than Ear (a), alongside improvements across the frequency range.
More bass does not automatically mean better sound.
Some users prefer powerful low frequencies while others want more neutral tuning. The stronger point is that Nothing also provides extensive control through the Nothing X app.
Ear (3a) includes four preset sound profiles and an adjustable 8-band equaliser, allowing users to create more personalised tuning. Equaliser profiles can also be shared through QR codes.
That degree of control is a meaningful advantage for enthusiasts who dislike being locked into the manufacturer’s default sound signature.
Nothing says Ear (3a) can provide noise reduction peaking at 45 dB.
Adaptive ANC automatically changes the level of cancellation according to surrounding noise, while Transparency Mode allows environmental sound back in when required. Nothing also claims stronger reduction around the human-voice frequency range compared with the previous model.
Those figures sound promising, but ANC quality requires independent testing.
Real performance depends on:
Ear (3a) now includes four ear-tip sizes, including a new XS option, which should help more users achieve an appropriate seal.
Ear (3a) also supports Static Spatial Audio.
Unlike head-tracked spatial systems where the virtual sound field changes as you move your head, Nothing describes its implementation as keeping the apparent audio source fixed in front of the device even when the listener turns their head.
This can make movies and selected music feel wider and more immersive, although spatial processing remains highly preference-dependent.
Some listeners love it. Others return to ordinary stereo after a few minutes.
Nothing claims the earbuds can provide:
With ANC off
With ANC on
Fast charging is also supported. Nothing says five minutes in the case can provide around one additional hour of playback under its laboratory test conditions.
Actual results will vary with ANC, volume, calls, codecs and wireless conditions.
The charging case also receives a small but clever visual update.
Instead of one conventional indicator, Ear (3a) uses a 1×3 status-light arrangement.
Different light patterns communicate:
It is a very Nothing-like detail: simple information communicated visually rather than through another screen.
Both the earbuds and charging case carry an IP54 rating under controlled laboratory testing.
That provides resistance against limited dust and water splashes, making the earbuds suitable for workouts, sweat and light rain. Nothing explicitly warns that they are not intended for swimming, showering or immersion.
This is currently one of the biggest questions for H View readers.
As of 8 August 2026, Ear (3a) does not appear in Nothing India’s current online product catalogue, although Nothing India’s support system already lists Ear (3a) as a supported product. Nothing Community discussions also contain repeated questions from Indian users asking when it will launch locally.
So we should not invent an Indian price by simply converting the $99 global price into rupees.
Until Nothing announces Indian retail pricing and availability, buyers should wait for official information rather than assuming imported pricing will match a future local launch.
Ear (3a) looks especially interesting for:
It may be less attractive for:
Audio Snapshot allows Ear (3a) users to capture a short section of audio they are listening to, similar to taking a screenshot. Depending on the selected mode, it can include audio from before and after the trigger.
Yes. Nothing says Audio Snapshot can include up to approximately 30 seconds of audio from before the user triggered the capture.
Yes, in supported regions. Nothing says the function can work with cellular and certain third-party calling applications, but users must comply with applicable recording and privacy laws.
Yes. Nothing lists Active Noise Cancellation reaching up to 45 dB under its specified conditions.
Nothing claims up to 10 hours from the earbuds and up to 42 hours total with ANC disabled. With ANC enabled, Nothing lists up to six hours from the earbuds and 25 hours including the case.
At the time of writing on 8 August 2026, Ear (3a) is listed in Nothing India’s support system but does not appear in the company’s current Indian online product catalogue. Official Indian pricing has therefore not been confirmed through the storefront.
