Nothing Ear (3a) Review: Feature-Packed, Short on Battery

As an Amazon Associate I earn from qualifying purchases. Disclosure

Overview

Budget noise-cancelling earbuds usually save money by dropping things: the hi-res codec, the detailed EQ, the water-resistant case. The Nothing Ear (3a) keeps all three and adds a rare trick: 32 MB of onboard storage that lets you save a clip of whatever you’re hearing or record a phone call with a pinch of both stems. It is the successor to 2024’s Ear (a) and sits below Nothing’s flagship Ear (3), in white, black, yellow or pink.

The changes from the Ear (a) are mostly inside. A larger 12 mm driver replaces the old 11 mm one, Bluetooth moves to 6.0, and the Nothing X app now offers an eight-band parametric EQ that the Ear (a) lacked. The case gains an IP54 rating and a three-segment status light. The default sound leans hard on bass, though, and the case is fussier than it should be.

Key Specifications

Nothing Ear (3a) Sound Quality and EQ

Out of the box, the Ear (3a) is tuned for bass, with more of it than the Ear (a) had. How much that matters depends on who is listening. Gizmodo liked the default sound and couldn’t hear a difference from the flagship Ear (3), though T3 and WhistleOut both found the Ear (3) sounds better. Expert Reviews found the stock tuning muddy and boomy and called the equaliser “a must.” BGR landed in between: energetic out of the box, but heavy enough to crowd the midrange on most tracks.

SoundGuys’ panel model predicts most listeners will enjoy the stock sound: the default Balanced preset and More Treble both scored above 4.6 out of 5. Compared only against other headphones and earbuds, though, their timbre score fell to 3.4, the middle of “okay,” and SoundGuys’ own reviewer found the stock sound far too bassy.

The fix is in the app. The Nothing X app offers simple presets plus an eight-band parametric EQ, and you can load tunings other owners have shared. With the low end pulled down they show far more detail, and BGR heard a warm midrange with crisp treble that never turned harsh.

LDAC: Sony’s hi-res codec is an uncommon extra at this price. On an Android phone, Expert Reviews heard a little more detail and slightly better instrument separation with it switched on. It comes at a battery cost, covered below.

What’s missing: There is no hearing-test EQ that tunes the sound to your ears, a feature the Ear (3) has. Spatial audio is the fixed kind with no head tracking, and testers found it added little.

Noise Cancelling and Transparency Mode

Nothing rates the adaptive noise cancelling at up to 45 dB across 40 to 5,000 Hz. In SoundGuys’ lab, it cut outside noise by an average of 80.9% in perceived loudness, enough for a normal commute, with its weakest results in the high frequencies. That pattern shows up in daily use too: low rumble from trains, planes and fans is dulled, while voices and sharper sounds get through.

The testers split on how it ranks. BGR rated it as good as or better than anything else at this price and nearly as effective as the Ear (3). Expert Reviews called it solid but not among the better options in the class, pointing to the OnePlus Buds 4 for stronger cancelling, and Gizmodo still heard train screeches and announcements on the subway. Against the Ear (3), T3 found the flagship’s noise cancelling noticeably better, while Expert Reviews rated the 3a ahead thanks to its better seal.

Transparency mode drew the same split. Expert Reviews found it improved and natural-sounding, while BGR thought it sounded unnatural enough to leave off except for quick conversations.

Battery Life and Charging

Nothing rates the earbuds at up to 6 hours with noise cancelling on and 10 hours with it off, or 25 and 42 hours with the case. Those figures assume AAC: switching to LDAC cuts the ANC-on rating to 4.5 hours. Each of the three rivals in the table below is rated for 8 hours or more with ANC on. Testers split on how much that matters: BGR puts it on the lower end and SoundGuys scores the battery below average, while T3 calls it about par for this kind of earbud and Expert Reviews got slightly more at lower volume.

The ratings hold up in testing. SoundGuys ran four battery tests with ANC off, and the earbuds died at almost exactly the 10-hour mark each time. In Gizmodo’s test, an hour at 50% volume used 15% of the charge, which works out to a little over six and a half hours.

Charging is quick, at about an hour of playback with ANC off from a five-minute top-up and 70 minutes for a full charge over USB-C. There is no wireless charging, which BGR counts as a real miss even at this price, while 9to5Google needed to top up the case so rarely that it didn’t matter.

Fit, Controls and the Charging Case

Comfort is a strength. Each bud weighs about 4.5 g, the four tip sizes now include an extra-small, and testers wore them comfortably for hours at a time, with BGR finding they stayed put through workouts. Expert Reviews called them the most comfortable and secure Nothing earbuds yet, though it still found the EarFun Air Pro 4+ and a few other rivals more secure.

Controls are pinches on the stems rather than taps, which avoids accidental presses when you adjust the buds. Expert Reviews could remap single, double and triple pinches and pinch-and-hold in the app, including for volume and noise-control modes, though T3 found it needed the phone to change volume.

The case draws the most design complaints. Its raised lip makes it awkward to open one-handed, and two testers needed a fingernail to pry it. Testers split on its size: T3 and WhistleOut found it chunky, while 9to5Google found it smaller than the Ear (3)’s case and Expert Reviews called it pocket-friendly. The buds can also sit at a slight angle when you drop them in, and SoundGuys found a bud left askew can miss its charging contacts. On the plus side, the case is IP54-rated like the earbuds, which the Ear (a) case wasn’t, and its three-segment light shows the charge level and pairing status.

Calls and the Recording Features

Each earbud has three microphones, and Nothing added mesh to cut wind noise. SoundGuys’ windy-conditions call sample was its standout result, usually where earbuds fall flat, though echo crept in in a reverberant room. Expert Reviews still heard wind whistling through the microphones while listening, and WhistleOut found a big gap in microphone quality to AirPods Pro and the Ear (3).

Audio Snapshot: Pinch both stems and the earbuds save up to 60 seconds of whatever is playing, with an option to include up to 30 seconds from before the pinch. Clips sync to the Nothing X app, where they can be transcribed. 9to5Google noticed the clips sound worse than the audio did through the earbuds.

Call recording: The same pinch during a call records up to two hours on the buds, and the other person hears an alert that recording has started. Recording laws differ from place to place, and some require every party’s consent. Transcription runs free on the phone, while a more accurate cloud “Pro” tier is free for three months and then needs a paid subscription. SoundGuys notes that recording and transcription need a Nothing account.

Several testers saw little everyday use for them, though Gizmodo, which interviews people for work, found call recording useful; they matter mainly if you record interviews or work calls.

The rest of the connection list is complete for the price: two-device multipoint, Google Fast Pair on Android, a low-latency mode for games and video, and find-my-earbuds in the app.

How Does It Stack Up Against the Competition?

As of October 2026, all four sell in the same budget tier on Amazon, so the choice comes down to battery, codecs and extras.

Nothing Ear (3a): Worth It for Budget Buyers Who Like to Tune Their Sound

Buy the Ear (3a) if you’ll spend ten minutes in the EQ. Its strengths are the ones you notice every day: a comfortable fit, reliable pinch controls, LDAC and multipoint, and a sound that rewards a little tuning. The recording features work as promised. If you mostly listen in commutes of an hour or two and charge each night, the rated 6 hours with ANC on won’t get in the way.

Look elsewhere if noise cancelling comes first: Expert Reviews found stronger cancelling at this price, though BGR rated it among the best in the class. The EarFun Air Pro 4+ supports aptX Lossless and charges wirelessly, and Expert Reviews rates it the better all-rounder, while the Soundcore Liberty 5 adds IP55 protection. If you want Nothing’s own step-up, the Ear (3) adds wireless charging and a hearing-test EQ, and two of the testers found it sounds better.
