Anker Soundcore Space A40 review

Anker Soundcore Space A40 in-ear earphones offer a natural audio experience and solid ANC at an affordable price. Anker's Soundcore Space A40 in-ear earphones offer a natural audio experience, including active noise cancellation, at a price much lower than you might expect.

The Anker Soundcore Space A40 brand from Anker Innovation won’t be as well-known to most consumers as brands like Sony, EPOS, Beats, Bose, or Apple’s AirPods. However, the Anker Soundcore Space A40 is a comparatively affordable $120 as opposed to the $200 to $300 you can typically anticipate to pay for a pair of earbuds from such businesses. The Space A40 doesn’t sound like you’re listening to music through cotton wool, unlike other earbuds in that price range.

The Anker Soundcore Space A40 are the best active noise cancelling wireless earbuds under $100 that are currently available. They are more affordable and provide a stronger battery than the Anker Soundcore Liberty 3 Pro. Excellent sound quality and natural sound are produced with the Space a40. To make themselves stand out even more, they can also use a companion app. And I also hope that the details in this Anker Soundcore Space A40 review will help you to make a wise purchase decision.

With their mid-range price, the Anker Soundcore Space A40 earbuds accomplish a significant goal: bringing excellent sound and noise cancellation to a reasonable price point. And while these have the brand’s renowned silk drivers, Hi-Res audio certification, and AI-driven ANC, do they actually live up to expectations? Has Anker recovered from the slightly disappointing Soundcore Liberty 3 Pro and resumed its previous glories? Yes, to a tee. But allow us to elaborate more.


Included in the Space A40 package are Anker Soundcore Space A40 earphones, a wireless charging case, a USB-C charging cable, 5 sizes of earphone tips, a quick start guide, and a safety manual. The quick start manual contains all the information you need to start using the Space A40 earphones immediately after purchase. Before charging the earbuds, we followed the instructions to check which tips were best for us. On our Android phone, we had to download the Soundcore app.

The Soundcore app is also available on the App Store, which will please iPhone users. We used the fit test in the app with the Space A40 buds and our chosen size (Small) tips to check the fit. The software instructed me to insert the earphones, play a little music clip, and adjust the volume on our phone. The app claims that every size except for XL offered a good seal, despite the fact that they were either too big or too small for our ears.

This is significant because both earbuds had a decent seal. For the most comfort, we eventually opted with the size small tips. The earphones are light and secure enough to use all day without feeling unpleasant even when worn for extended periods of time. The Anker Soundcore Space A40 earbuds were delivered in a sleek black color (though they also come in blue and white).

The charging case is made of matte-finish black plastic with rounded corners, an LED charge display window, a metallic Soundcore logo, and a Bluetooth pairing button. The earbuds themselves have a black plastic body, a matte silver touch-sensitive gesture area with a logo in the center, two charging pogo pin pads, and a total of six microphones. Once you’ve got the Space A40 earbuds set up, Bluetooth pairing was simple, and every time you remove them from their charging case, they connect promptly.


Even for extended periods of time, we found the Anker Soundcore Space A40 to be incredibly comfortable. In our opinion, their rounded form is quite ergonomic and strikes the ideal Goldilocks balance between being large enough to make excellent contact with our concha and without being so large that it causes our ears to feel stifled. We are quite content with the default medium tips, but Soundcore can assist you in finding your ideal size using the fit test tool found in the Soundcore app, which plays a series of tones to check for any sound leakage.

The earbuds were fairly secure once we were sitting. They just slightly loosened while we was talking, but we are found that to be the case with practically all earphones. There will inevitably be the occasional unintended hit because the controls are touch-sensitive. However, the A40’s touch controls are excellent overall. The surfaces are big and simple to tap, and the app allows you to choose (or disable) a tap confirmation tone, which we find to be quite useful.

The only issue we have with them is that the tones lag a little bit; you tap, and then a tone comes through a second later. Faster response times are preferred by us. Additionally, you may totally change what the tap gestures perform. There are six in total, including single, double, and tap-and-hold on each side. In the app, you may choose what each one performs.


The Anker Soundcore Space A40 multipoint connection, which enables you to pair the earphones with two devices—such as your phone and laptop is its key feature. It’s an exceptional feature that costs less than $100 and works particularly effectively for calls. If you are playing music on your laptop when a call comes in, the music will immediately transition to your phone. you watch a video on your phone and use your laptop to join a video call.

The switch will work equally well. When there are no calls, it doesn’t switch as quickly. To switch to a video or song on your other device, you must first pause your current music or video. Not a big deal, but the instant switching of the Earfun Air S is considerably more useful. But this is also wonderful. You are no longer required to have a separate laptop headphone. Like other Soundcores, connection is excellent throughout.

Up to 10 meters away from your device, the Bluetooth connection is reliable, and you can always choose to use one or two earbuds. Nevertheless, music doesn’t stop when you remove an earphone. The touch panels are simple to find blindly and respond to input quite effectively. The controls are programmable via the app, but because you “only” have a single-tap, double-tap, and hold-control option on either side, it’s not possible to have all the controls on the earbuds. For example, you might have to give up the option to return a track to enable the game mode.

Noise Cancelling

You’ll find many wireless earbuds for $100 (or even less) that make noise cancellation a promise, but in practise, most of them simply provide minimal noise cancellation just enough to make the claim, but nothing more. Although we are not sure we agree with Soundcore’s remarkable claim that the Anker Soundcore Space A40 reduces noise by up to 98%, the noise cancellation on these earbuds is genuine.

They are particularly effective at suppressing a wide range of sound frequencies when the ANC mode is used. Our home office is located approximately eight feet from a noisy bathroom fan, but the A40 virtually eliminates that noise. Transparency mode, which is frequently average on earphones at this price, is unexpectedly effective.

Voices are audible and the outer world becomes fully audible. Not much is, really, at any price, as amazing as Apple’s AirPods Pro. The Soundcore app’s ability to allow you choose which modes you wish to access when you switch the ANC feature is something we really like. You can select two options from ANC on, off, or transparency, or you can alternate between all three. Too many earphones prevent you from doing this.

Audio Performance

Even though the noise cancellation is excellent, you may also be interested in the sound quality. Although we noticed the bass isn’t as strong as some of Anker Soundcore Space A40 other earbuds, it is still fantastic. With the Soundcore app, you may change this if you’d like and activate the Bass Boost equalization. If you’d like, you can even design your own equalizer settings.

If your phone can handle LDAC and Hi-Res audio, which is currently limited to specific Android devices, the earphones also support those formats. Whether you’re using your own music files or a streaming service like Apple Music, Spotify, or Pandora, music sounds fantastic on these earphones. The audio quality does improve, though.

The Anker Soundcore Space A40 , like many other Anker products, has changeable EQ settings in the app for extra fine-tuning. The pair of 40mm drivers that power the listening experience do a good job out of the box of providing a balanced soundstage. LDAC high-resolution audio is also supported in addition to Bluetooth 5.3 connectivity.

Call Performance

High-resolution audio and adaptive ANC plus with transparent mode are features of the Anker Soundcore Space A40. With six AI algorithm microphones, they offer excellent call quality as well as exceptional sound quality. Additionally, the Space A40 offers multipoint connectivity. They also have a rapid charge feature, and it charges so quickly. Strong battery and compatible wireless charging are other features (10 minutes get additional power of up to 4 hours).

The call quality is excellent in quiet environments for both phone and video conversations. Your voice is loud and full-sounding by nature. Unfortunately, everything around you is constantly changing. The sound effects themselves are almost entirely absent from the conversation, but they also draw your voice along with them. This is true whether they are coming from accelerating vehicles or workplace noises like door slams and moving chairs.

On occasions of constant noise, you might sound too muffled or perhaps inaudible. On the Space A40, video playback is faultless, and this time around, Soundcore also provides a low-latency gaming option. It does an excellent job of matching sound effects to the action you are watching on the screen and provides a good amount of localization of gunshots and movement around you.

Battery and Charging

Because the Space A40 is such an excellent offering, both the performance and battery life left us pleasantly delighted. Although that is with ANC turned off, you will find that you can go up to a solid 10 hours without needing to recharge. In other words, the Space A40 can provide a lot of life if you desperately need extra battery life and are willing to live in a bubble. With ANC turned on, the battery life drops to around 5 to 7 hours, depending on whether you’re using LDAC, which this device supports, to listen to high-resolution audio.

Because of the Anker Soundcore Space A40 long battery life, wearing them all day is simple. According to Soundcore, the earbuds have a 10-hour battery life and can be charged for up to 50 hours. If you use them without ANC, we have discovered that this is true. However, there is a noticeable reduction in battery life when ANC or LDAC is activated, which is consistent with the lab test requirements of eight hours with ANC or six hours with LDAC.

You can basically get anywhere between 25 and 50 hours of battery life from Anker Soundcore Space A40 , and that’s not bad. The case itself is good enough for a good five additional charges. To Soundcore’s credit, the addition of wireless charging a feature you often have to pay quite a bit more for is also a complete surprise. Although most people consider wireless charging in an earphone case to be a truly premium feature, it is included in a pair of $130 truly wireless noise-canceling earbuds. However, in a good way.

Final Words

The Soundcore Space A40s are a true return to form for Anker after the Liberty 3 Pro; they are a fantastic combination with excellent value. These were a pleasure to use because they have excellent sound quality, strong ANC, and an incredible battery life for the price, all bundled into a stylish pair of earbuds and a small, portable case. Even though there are a few minor flaws with call quality and touch responsiveness, these are still much outweighed by how excellent these are.
