Anker Soundcore Space A40 Review (2026): Feature-Packed ANC

This Anker Soundcore Space A40 review covers a pair of true wireless earbuds that put noise cancelling, a long battery and a long feature list in the mid-range part of the market. It is aimed at commuters and everyday listeners who want a lot of capability and customisation without paying for a flagship. The sections below are based on the manufacturer's specs and on what independent expert reviews report, not on hands-on testing by us.

What the Soundcore Space A40 is

The Space A40 is Soundcore's mid-range noise-cancelling earbud. The headline feature is adaptive ANC that adjusts to your surroundings, and Anker rates it at up to 98% noise reduction. Around that sit LDAC for Hi-Res wireless audio on compatible devices, Bluetooth multipoint, and a charging case that works wirelessly or over USB-C.

That combination explains why it has been recommended in 3 independent expert guides. It averages 7.9/10 across 4 expert reviews, a solid score that reflects real strengths and a few clear weak spots. We cover both below.

Anker Soundcore Space A40 review: design and fit

Each earbud weighs 4.9g, so these are light in the ear. Reviewers describe the fit as light and comfortable, which matters for long commutes or work sessions where heavier buds get tiring.

A common criticism is that the fit can loosen without stability fins, so people who move around a lot, or whose ears don't hold buds securely, may find them less stable than they'd like. Reviewers also note there are no wear sensors. Playback won't pause automatically when you take a bud out, so you'll rely on the controls instead.

Those controls are touch-based. Touch controls are convenient and keep the buds compact, but they can be easy to trigger by accident while you adjust the fit.

Water resistance is IPX4, which covers splashes and sweat. That is enough for workouts and rainy walks, but it isn't a rating for submersion or heavy water exposure.

Noise cancelling: the main draw

Adaptive ANC is the reason most people will look at the Space A40. Rather than sitting at one fixed strength, it adjusts to the environment around you. For a commuter that means the earbuds respond as you move from a quiet street to a busy train platform or a noisy carriage.

Reviewers praise the ANC, especially against low-frequency rumble. That is where the noise cancelling does its best work.

The flip side is a common criticism. ANC is weaker on high-pitched and mid-range noise. High-pitched and mid-range noise will be reduced less than low-frequency rumble. Think of it as excellent against rumble and decent, not complete, against everything else. If your environment is full of chatter, set your expectations accordingly.

Sound quality and customisation

The earbuds use a 10mm double-layer diaphragm driver and cover a frequency response of 20~20 kHz. Codec support is SBC, AAC and LDAC. The practical meaning is that iPhone users get AAC, while LDAC is there for compatible devices, typically Android phones, that can take advantage of the higher-quality connection.

The tuning side is where Soundcore does well. The companion app offers EQ presets, and HearID creates a personalised sound profile. Reviewers praise how extensive this tuning is. If the stock sound isn't to your liking, you have a lot of room to adjust it.

That said, experts say the sound can feel slightly hazy and lacks audiophile-level detail. LDAC support might suggest a hi-fi experience, but it is better read as a bonus feature than a promise of detailed, analytical sound. These are earbuds for enjoyable everyday listening, and the EQ helps you shape them to taste. They aren't for critical listening.

Battery life and charging

Battery life is among the Space A40's biggest strengths, and the specs are clear on it:

• Up to 10 hours per charge, and 50 hours with the case.
• With ANC on, 8H on the earbuds and 40H with the case.
• With LDAC on and ANC off, 6H on the earbuds and 30H with the case.

The lesson is that the way you use them changes the numbers. Switching on ANC and especially LDAC trades some endurance for performance. Even in the LDAC configuration, the case-backed total is large enough that many people would charge only occasionally.

Fast charging helps too. A 10-minute fast charge adds 4 hours of playback, so a short top-up before leaving the house covers a good part of a commute. The case charges wirelessly or by USB-C. If you have a Qi-style wireless charger on your desk or nightstand, you can drop the case on it and forget the cable.

Connectivity and calls

The earbuds use Bluetooth 5.2 and support multipoint connection with 2 devices at once. That is useful if you move between a laptop for work and a phone for calls and music, because you don't need to disconnect and re-pair each time.

For calls there are 6 microphones with AI processing, intended to deliver clearer voice pickup. Reviewers are less convinced. A common criticism is that call quality is average, and voices can sound thin or distant. If you take many calls on your earbuds, that is the area where these fall short of their other strengths. They're fine for the occasional call but are not a reason to buy.

What experts like and what they criticise

The published scores give a consistent picture. RTINGS scores it 8.1/10, SoundGuys gives it 7.4/10, Controller Nerds rates it 8/10 and Scarbir gives it 4 out of 5. Together they average 7.9/10. These are good scores, not exceptional ones.

What reviewers praise:

• Strong adaptive noise cancelling, especially against low-frequency rumble.
• Long battery life, backed by a quick 10-minute charge.
• A rare mix of LDAC, multipoint and wireless charging for a mid-range price.
• A light, comfortable fit with extensive EQ and HearID tuning in the app.

What reviewers criticise:

• Average call quality, with voices that can sound thin or distant.
• Weaker ANC on high-pitched and mid-range noise.
• Slightly hazy sound that lacks audiophile-level detail.
• No wear sensors, and a fit that can loosen without stability fins.

The pattern is straightforward. The Space A40 is strongest on features, battery and noise cancelling against steady rumble, and weaker on voice pickup and sonic refinement.

Who should buy it, and who should skip it

Buy it if:

• You commute and want ANC that handles engine and road rumble.
• You want long battery life and quick top-ups.
• You like adjusting sound with an app, EQ presets and HearID.
• You switch between two devices and want multipoint.
• You value wireless charging and LDAC as extras at a mid-range price.

Skip it if:

• You make many calls and need clear voice pickup.
• You work in a place full of voices or other mid-range and high-pitched noise and need ANC to deal with it.
• You want audiophile-level detail and clarity.
• You want automatic pause when you remove a bud.
• You have ears that find light earbuds without stability fins insecure.

How it fits in its category

In general terms, true wireless earbuds with ANC tend to make you choose between price, battery, features and refinement. The Space A40 sits in the mid-range tier and leans toward features and endurance rather than call quality or high-end sound. That makes it a practical choice for value-minded commuters, while people who care most about calls or detailed sound should weigh other options with those strengths.

Verdict

The Anker Soundcore Space A40 is a sensible pick if you want a lot of capability in one set of earbuds. Adaptive ANC, a long battery, fast charging, LDAC, multipoint and wireless charging make it a well-rounded commuter companion, and the app tuning adds flexibility. Its limits are well documented: average calls, uneven noise cancelling beyond low-frequency rumble, and sound that is enjoyable rather than detailed. If those trade-offs match your priorities, it is an easy product to recommend. If calls or audiophile detail come first, keep looking.
