The Anker Soundcore Space A40 Truly Wireless are lower mid-range noise cancelling in-ears with a few extra features. Notably, there's an adaptive active noise cancelling (ANC) system, which outperforms similar products from this manufacturer, like the Anker SoundCore Life P3 Truly Wireless. They also support LDAC codec, which is Sony's proprietary codec for hi-res audio, and have robust sound customization features via their companion app. You can even wirelessly recharge their carrying case, making them a solid choice if you want affordable yet versatile in-ears.

Our Verdict

7.1
Neutral Sound 

The Anker Space A40 are decent for neutral sound. Their sound profile brings a warm tonality to vocals and instruments in your favorite tunes. Out of the box, the low-bass has a balanced amount of punch and rumble, and their underemphasized treble veils clarity and details in the mix. Thanks to the graphic EQ and presets in their companion app, you can switch up their sound. Of course, as closed-back earbuds, their soundstage isn't very open or immersive feeling.

Pros
  • Sound customization features available via companion app.
Cons
  • They lack stability fins and can pop out of your ear.
8.2
Commute/Travel 

The Anker Space A40 are great for commuting and travel. Thanks to their adaptive ANC system, these headphones can block out background noises like bus and plane engines. They boast a comfortable fit and a portable design that's easy to take with you on the go. Plus, they last over eight hours continuously, and their carrying case supplies an extra four charges if you need it.

Pros
  • Amazing full range noise isolation performance.
  • Comfortable and well-built design.
Cons
  • They lack stability fins and can pop out of your ear.
8.0
Sports/Fitness 

The Anker Space A40 are great for sports and fitness. They're comfortable enough for long workouts and sturdy enough to withstand wear and tear. If you like to exercise outdoors, there's even an IPX4 rating for water resistance to help protect them against the elements. They'll stay in your ears for more moderate workouts, but since they lack stability fins, their fit isn't quite as secure as some other models.

Pros
  • Comfortable and well-built design.
  • Rated IPX4 for water resistance.
Cons
  • They lack stability fins and can pop out of your ear.
7.5
Office 

The Anker Space A40 are good for office use. With a continuous battery life of over eight hours, they last through most work days, and their carrying case offers some extra charges if you need to top them up. You can pair these headphones to up to two devices at a time, making it easy to switch between your phone and your laptop. Also, their adaptive ANC system helps you focus on your work by reducing ambient noise, like the chatter of nearby coworkers.

Pros
  • Amazing full range noise isolation performance.
  • Comfortable and well-built design.
  • Supports multi-device pairing.
Cons
  • Mic has poor recording quality.
5.6
Wireless Gaming 

The Anker Space A40 are truly wireless headphones. While you can connect them to Bluetooth-enabled PCs, their latency is likely too high to be suitable for gaming, even when using their low-latency 'Game Mode'.

5.4
Wired Gaming 

The Anker Space A40 are Bluetooth-only headphones; you can't use them wired.

6.4
Phone Calls 

The Anker Space A40 are passable for phone calls. Their integrated mic has poor recording quality, so your voice sounds distant and sibilant to whoever's on the other end of the line. The mic can separate your voice from moderate background noise, but it's no match for louder environments like a busy street. You'll want to take your calls in quieter places if possible.

Pros
  • Amazing full range noise isolation performance.
Cons
  • Mic has poor recording quality.

    Differences Between Sizes And Variants

    The Anker Soundcore Space A40 come in three color variants: 'Black', 'White', and 'Blue'. We tested the 'Black' variant, and you can see our model's label here. If you encounter another variant of these headphones, please let us know in the forums, and we'll update our review.

    Popular Headphones Comparisons

    The Anker Space A40 are truly wireless headphones with a powerful adaptive ANC performance. They can block out an amazing amount of ambient noise that rivals high-end competitors like the Sennheiser MOMENTUM True Wireless 3, and you can also switch to one of five manual ANC modes if you prefer a different level of noise isolation. Like the Anker Soundcore Liberty 3 Pro Truly Wireless, they also support LDAC codec for streaming hi-res audio on supported apps. Unfortunately, their mic's recording quality is similarly poor, so if you care about call quality, check out our picks for the best earbuds and Bluetooth headsets for phone calls.

    Check out our recommendations for the best wireless Bluetooth earbuds and the best noise cancelling earbuds.

    CMF Buds Pro 2

    There are good reasons to pick either the Anker Soundcore Space A40 Truly Wireless or the CMF Buds Pro 2. The primary reasons to choose the Anker are for the longer-lasting, continuous battery life and slightly better noise isolation. Meanwhile, the CMF are a bit more refined in design with a more stable fit, dustproofing, and a better microphone. Of course, your tastes will weigh in even with the presence of an EQ, because you might prefer the Anker's flat tuning or the CMF's more bassy sound profile.

    Anker Soundcore Liberty 4 NC Truly Wireless

    The Anker Soundcore Liberty 4 NC Truly Wireless and the Anker Soundcore Space A40 Truly Wireless are very similar earbuds. The Liberty 4 NC have a bassier sound than the A40, which EDM fans might appreciate. However, both can be adjusted with the companion app's graphic EQ and presets. Their ANC systems both work incredibly well, and they both have around the same continuous battery life. Ultimately, your preference between either will come down to what kind of design you want. The Liberty 4 NC have a bud and stem design that is slightly more stable, but the A40's bud-only design takes up less visual real estate and has a more subtle look.

    JBL Tune Buds True Wireless

    The JBL Tune Buds True Wireless are both bassier and more excited-sounding than the Anker Soundcore Space A40, which sound much more veiled in the treble and have a more controlled bass. Both buds can be customized with graphics EQs and presets. The JBL have a more stable fit and a longer continuous battery life. That said, the Anker have a much better ANC system that blocks out a wider range of frequencies than the JBL, so it depends on whether you want ANC or not.

    Anker Soundcore P40i

    The Anker Soundcore Space A40 Truly Wireless are quite similar to the Anker Soundcore P40i. Both the A40 and the P40i can isolate you from noise quite well. The A40 leak less audio and support the high-quality audio codec, LDAC. However, the P40i have a slightly longer battery life and are more stable. The buds also have somewhat better water resistance with an IPX5 rating instead of the IPX4 found on the A40. They otherwise share many of the same app features, such as a graphic EQ and 'Game Mode' to reduce latency.

    The Anker Space A40 look somewhat similar in design to the Anker Soundcore Life Dot 2 Truly Wireless. They have a stemless bud design with a glossy frame and a semi-matte touch-sensitive surface. The touch surface also has the manufacturer's logo, and these headphones come in three color variants: 'Black', 'White', and 'Blue'.

    These headphones have a comfortable in-ear fit. They don't have as deep of a fit as other headphones from this manufacturer, like the Anker Soundcore Life Dot 2 Truly Wireless. They also feel lightweight, and using the controls doesn't push the buds deeper into your ear. However, they can cause a plunging feeling when you're putting them in for the first time.

    The Anker Space A40 have good controls. There's a touch-sensitive surface on each bud, but they aren't the most intuitive to use since the layout splits controls on each bud. Luckily, you can use the companion app to remap the controls to your liking, and you can even add volume controls without losing other commands. There are also audible chimes while cycling between ANC on, normal mode, and transparency mode. There are tones available for tap feedback, too, but you'll have to activate this via the companion app.

    On the left bud:

    • Double tap: Skips to the next track.

    On the right bud:

    • Single tap: Plays and pauses audio.

    On either bud:

    • Double tap: Answers and ends calls.
    • Tap and hold for two seconds: Switch between ANC on, transparency mode, which allows you to hear your surroundings without taking out your earbuds, and normal mode.

    The carrying case feels good and sturdy. It's mostly made of matte plastic on the outside and glossy plastic inside the case. There are three LED lights at the front of the case to indicate the battery charge and a reset/pairing button on the back of the base.

    7.5
    Build Quality

    The build quality is good. They're mostly made of plastic, but the touch-sensitive surface feels a little cheaper than the rest of the body. The buds are certified IPX4 for resistance against water splashes, and they come with several different tip sizes to help you get the best fit.

    7.0
    Stability

    These in-ears are decently stable but lack stability fins to ensure a truly stable fit. They'll stay in place if you're listening to audio at your desk or on the couch, but talking and chewing can break the ear tips' seal, causing the buds to wiggle around. They can fall out if you wear them during moderate to intense physical activity. If you're looking for earbuds with a more stable fit, try the Samsung Galaxy Buds FE Truly Wireless, which have stability wings to keep the buds in place while you're moving.

    The Anker A40 have a warm sound profile with a bit of extra boom and punch. Bass guitars and kick drums come through as full-bodied, while mid-range instruments like keys and guitars are slightly emphasized in the low-mids, adding extra thickness to rhythm guitars. However, the high-mids are slightly pushed down which cuts down on the intensity of vocals. The low-treble sees a smooth de-emphasis that veils vocal articulation and clarity. Meanwhile, a sharp peak causes sibilants like cymbal harmonics to sound comparatively splashy but not full.

    Luckily, if you prefer a different sound, their companion app offers a graphic EQ and presets that change the sound profile to help you customize their sound. We also found there are minor changes to the frequency response when you turn off the ANC compared to when it's on.

    The Anker A40 have superb mid-range target compliance. The low-mids are slightly elevated with a touch more emphasis on chunky rhythm guitars with clear leads. The mid- to high-mid is a little bit rolled off, which weakens the intensity of vocals and instruments slightly.

    Their treble profile's target compliance is poor. The response is almost entirely underemphasized, resulting in very veiled vocals and instruments and dull sibilants like cymbals, which can sound uneven. In songs like Rock Me Amadeus by Falco, hi-hats in the first verse sound a bit lispy, while the lead singer's voice lacks detail. If you prefer a very warm treble range, you might like this, but equally, the app's EQ can change the treble's response to make it brighter if you want.

    The peaks and dips performance is okay, which indicates that these headphones control their sound profile well until the treble range. Most of the bass and mids are rendered smoothly, with very few minor bumps. A relatively small dip in the low-treble hurts the intelligibility of voices somewhat. The big peaks add piercing details to sibilants, like cymbal hits, followed by a steep dip that cuts out the full detail of those cymbal hits. In the higher registers, a big peak adds artificial brilliance and airiness, but hearing sensitivity can vary across people, so you might not be able to hear those highest frequencies.

    The imaging performance is outstanding. Generally, most Anker headphones have well-matched drivers, indicating the brand's quality control and ergonomics. It's worth mentioning that earbuds and in-ears tend to be better matched than their over-ear counterparts. Our unit's L/R drivers are also well-matched regarding group delay, phase, amplitude, and frequency response, which is important for accurately placing objects like voices in the stereo image. While there are a couple of minor peaks in the phase response's low to mid-mid, it's hard to hear with real-life content. Imaging can vary between units, though.

    As expected of in-ear headphones, their passive soundstage is bad. Activating the outer ear is a key component of creating an immersive soundstage experience, but these headphones don't do that by design. As a result, their soundstage sounds closed-off, unnatural, and small. Sound seems to come from inside your head rather than from speakers placed in the room around you.

    The Anker A40's weighted harmonic distortion performance is good. There's a peak in the low-treble range, which is more noticeable in the right driver at moderate and high volumes. Still, this peak is hard to hear with real-life content. The rest of the response falls within good levels, resulting in mostly clear and pure audio reproduction.

    The noise isolation performance is amazing. Unlike other budget-friendly picks like the Nothing Ear (stick) Truly Wireless, these buds have an adaptive ANC system, which automatically adjusts to the noise in your environment. If you prefer, you can manually set the amount of ANC between 'Low,' 'Medium,' and 'High.' The adaptive ANC can block out the low rumble of bus engines. It also cuts down ambient chatter and the high-pitched hum of AC units.

    The adaptive ANC can block out slightly more bass-range noise when it recognizes a 'High' noise environment than when the ANC is manually set to 'Strong.' You can see a comparison between these modes here.

    These buds have an ANC system that performs amazingly well in common scenarios. They do a great job of attenuating against the rumble of airplane engines and block out a lot of street noise. However, they really excel in office environments, where they effectively block out the sound of chatty coworkers and scraping chairs.

    Unlike other sounds, wind directly interacts with the ANC's microphones. Even though this sound doesn't reach your ears, the ANC system still tries to cancel it out, causing loud and unwanted noise. Fortunately, these buds feature a wind reduction feature in their companion app that can help mitigate this irritating sound while you're in windy environments.

    The integrated mic's recording quality is poor. Your voice sounds far away and sibilant. Our unit's right earbud also enters a feedback loop when using the mic, resulting in your own voice playing quietly by the right bud. When connected to a phone, the microphone sounds a bit more sibilant, which you can hear in the recorded speech file.

    We've noticed reports of the mic ceasing to work, sometimes in the middle of a call. We've been unable to recreate the issue, but on re-testing, we did notice that the microphone's noise gate is very sensitive and will sometimes cut off the beginning and end of words. Some users have had success fixing this issue permanently by resetting the earbuds, which you can learn how to do at this link.

    The battery performance is good. The manufacturer advertises 10 hours of continuous playtime, and with the ANC on, we measured eight hours using the LDAC codec. When using the SBC codec, which is the default Bluetooth codec, and with ANC on, we measured over nine hours. Turning the ANC off but still using the SBC codec also results in over ten and a half hours of battery life. Keep in mind that battery life can also vary depending on usage. If you need a top-up, their carrying case supplies an additional four charges, which is handy in a pinch. They also have an auto-off timer, which helps conserve battery life when not in use, and you can use one bud while the other charges.

    The Anker Space A40 have great Bluetooth connectivity. They support multi-device pairing, so you can connect your headphones to two devices simultaneously and have a game mode to help lower latency. Using Game Mode, their latency via SBC falls out of good values, so you'll notice a slight lip sync mismatch. If you disable this mode, you'll get even higher latency values, which can be annoying if you're streaming video. It doesn't seem like this mode affects LDAC latency, though, which is Sony's proprietary hi-res codec. This codec has high latency, but it won't be an issue if you're only streaming audio. However, you need to use compatible audio to benefit from this codec, and you can only connect to one device at a time.

      One interesting thing to note is that the ones I have are currently in version 06.39, and I’m experiencing the same issues. On the review, it says that the firmware they are using is 4.19, and their testing is only valid for Space A40’s with that firmware. The review needs an update, as the new firmware may have changed the ANC performance. I’m wondering what firmware your pair are on. If possible, could you check?

      Hi SebastianIGuess and hesido,

      Thank you for the feedback! Our results show that the noise cancelling of the buds performs similarly to passive isolation in the Treble range. The Mids could all depend on the speaker’s voice range, but overall, the mid-mid and high-mid attenuation is not improved as much with ANC as the overall Bass. That said, we will be looking at the ANC results on the latest firmware. We might not have this data right away, as we have recently released our 2.0 Test-Bench, and we are busy converting more headphones on this test bench.

      Cheers!

      I too bought thinking this had good ANC by referring to this review, but coming over from Sony LinkBud S, the mid and treble noise cancellation seems to be non-existant (other than what is provided by the seal of the tips). I’m checking the numbers and I should be expecting similar performance, but the feeling of isolation when I’m using the LinkBud S is not there. The bass part of the noise cancellation is excellent, much better than LinkBud S, in my experience. Unfortunately my LinkBud S left earbud is no longer producing proper sound, two months after the warranty ended; Sony’s got that planned obsolescence game down to a science, I guess). I hope this is a new issue which could be fixed later on if it’s software related, but I’d really like it if the ANC test here could be re-done with software updates or new pairs from the market.

      I usually want to block out music and speech when I’m at a cafe, and don’t really mind the rumble of traffic or the bass hum from the kitchen. I got these based on your recommendations and I’m finding that they really don’t do a good job of blocking conversation. It does make conversation in a quiet room less intelligible, but not less audible / grating; in a cafe it makes it more intelligible (and distracting) since bass isolation is pretty good. I’m thinking that ANC is just not what I want for my use case (blocking out voices and music) but I’ll take a look at the other reviews.

      These earbuds have been decently pleasant this past week, with one major issue being the ear-tips. My left ear struggles to get a seal with any of the provided tips. They’re also pretty uncomfortable, but that’s subjective. I can see the issue with smaller ears, where the side of the buds put pressure on the upper part of the lobe. That’s just my experience, though.

    5. Update: After hearing reports that it would cease to work, we re-tested these earbuds’ microphone. We were unable to reproduce the issue but noticed that the noise gate is very sensitive. We’ve updated the Recording Quality section of this review to note this retest and added a link to reset your headphones should you encounter this issue.

      There seems to be an issue with the mic during calls where it basically stops working. That makes them pretty useless for me. There’s a thread about this on the Anker subreddit “Anyone having their mic stop working on the Space A40?”.

      I get this all the time in calls or WebEx/Zoom. They are a great buy for listening, but I can’t recommend them for communication.

    8. Update: This review’s Sound tests have been updated following Test Bench 1.8. Text changes have also been made throughout the review, including the usages, to match these results.
