Following last year's launch of the Nothing Ear (3) as the flagship model, the brand expands its audio lineup with the release of the new Nothing Ear (3a). This latest offering aims to deliver a well-balanced alternative within the company's catalog, trimming back a few premium hardware extras while debuting productivity-focused software features like quick audio capture and conversation recording. If you want to see how this new addition stacks up against last year's model, we break down all of their technical differences in detail.
Design and case
Transparent design defines the visual identity of the brand across both products, though there are key changes in the construction of the case. The Nothing Ear (3) maintain the classic square format (55.5 x 55.5 mm) with a total weight of 71.4 grams for the set and earbuds weighing 5.2 grams each.
The Nothing Ear (3a) opt for a pillbox-style case design, more rectangular (64.8 x 48.95 mm), which manages to bring the total weight down to 40.92 grams. Additionally, their earbuds drop to 4.53 grams each, a lightness that delivers excellent comfort during extended listening sessions. Both models feature an IP54 dust and water resistance rating for both the earbuds and the charging case.

Sound quality and equalization
On the acoustic side, both models share a very solid technical foundation. Both the Ear (3) and Ear (3a) feature a 12mm dynamic driver with a PMI + TPU diaphragm and a frequency response of 20 Hz to 40,000 Hz. Both support SBC, AAC, and LDAC codecs, along with Hi-Res Wireless certification and Static Spatial Audio.
The difference in sound performance lies in the customization offered by each model. The Nothing Ear (3) include exclusive features in the Nothing X app, such as Personal Sound to adapt the equalization to the user's actual hearing and a dynamic bass enhancement system. The Ear (3a) retain the advanced equalizer and shared profiles, but forgo this personalized hearing test.
Noise cancellation and call technology
Adaptive active noise cancellation (ANC) reaches a depth of 45 dB In both cases, effectively isolating ambient noise in public transport or workspaces.
Voice capture clearly gives the Nothing Ear (3) a competitive edge. In addition to including three MEMS microphones per earbud, they incorporate a VPU sensor (Voice Processing Unit) on each side that captures bone conduction vibrations. Its case adds a Talk button dedicated to activating the Super Mic function during calls or quickly communicating with voice assistants and Essential Space.
The Nothing Ear (3a), on the other hand, uses a configuration of three MEMS microphones per earpiece backed by an ENC algorithm. They achieve remarkable clarity in standard calls, although on paper, they don't reach the level of isolation in windy environments offered by the Ear (3).

Battery and charging type
The internal battery specifications are identical: 55 mAh in the earbuds and 500 mAh in the charging case. However, the Nothing Ear's (3a) power management system allows for extended total battery life.
With the AAC codec and ANC turned off, the Ear (3a) offer up to 42 hours of total playback with the case (10 hours on the earbuds). The Nothing Ear (3) reach 38 total hours under those same conditions (10 hours on the earbuds). With ANC enabled, battery life lands at 25 hours for the 3a versus 22 hours for the Ear (3).
In exchange for that slight difference in battery life, the Nothing Ear (3) offer Qi wireless charging in the case—a very convenient extra that takes about 120 minutes for a full charge. The Ear (3a) rely exclusively on the USB-C port.
Audio Snapshot and call recording in Ear (3a)
Where the Nothing Ear (3a) provides a differentiating value is in its intelligent software functions integrated with Nothing X, designed for productivity and daily workflow:
Audio Snapshot: allows you to capture up to a minute of any media content you are listening to directly from the earbud with a pinch gesture. You can even set it to go back and save the 30 seconds prior to the moment you start recording.
ADVERTISING
Call recording: lets you record up to 2 hours of phone calls or online meetings to listen back to them in Nothing X. During the call, an alert tone notifies both parties that the session is being recorded. As of the time of writing this article, this feature is currently not available in Spain.
Intelligent management in Nothing X: directly from the app, you can replay recordings, generate automatic summaries, send text transcripts, or share specific quotes from longer conversations.
Connectivity
In wireless connections, the Nothing Ear (3a) debut Bluetooth 6.0 with an advertised range of up to 15 meters, while the Ear (3) features Bluetooth 5.4 with a range of 10 meters. Both support Dual Connection for easy switching between two devices.

Which one should I buy? Which one is better?
The Nothing Ear (3) are the recommended choice if you value wireless charging, peak sound precision tailored to your ear, and top-tier voice quality on calls thanks to the VPU sensor and the Talk button on the case.
The Nothing Ear (3a) become a highly attractive buy for those who prioritize lightness, longer total battery life, superior Bluetooth 6.0 range, and unique productivity tools such as Audio Snapshot and call recording with transcription in the Nothing X app.
The choice between both models depends on the usage profile you are looking for. In my view, unless you care about a specific feature or prefer one design over another, the audio performance on both is exceptional, which is what matters most. Based on my daily needs, given that I don't use the Talk button, I would lean toward the Nothing Ear (3a) for their lightness and case design.

I think features like Audio Snapshot and call recording should come to the Ear 3 in an update, since they're the brand's top-of-the-line model in that format. If it can't be done via hardware, since I understand the 3a has a small amount of internal memory, then it should be a software feature through the Nothing X app.

I was just thinking the same thing yesterday. It's one of the things that bothers me, that the most premium product lacks some features that lower-end models have. Nothing should be keeping an eye on these things… I'd be very surprised if the Ear (3) couldn't do that; I'm sure it also has that small amount of memory for the firmware and its operation.
