Welcome to my review of the Soundcore Space A40 Adaptive Noise Cancelling Earbuds. Soundcore is quite a well-known brand at this point, and their latest “Space” range promise to block even more noise for you to focus and/or relax. They are said to block up to 98% of the noise around you.
Block Out 98% Of The World!
So how does the Soundcore Space A40 actually perform? Continue reading to find out more about them.
The Hardware
So the hardware itself is a typical “truly wireless” earbud design. They fit in the ear nicely and stay put without falling out of your ears. Should the provided tips not fit in your ear, you have a choice of 5 sets of tips to get that perfect (or as close as possible) fit to your ears.

They come with a charging case that can be charged with the provided USB C cable, or wirelessly charged.
Key Features:
- Bluetooth 5.3 connectivity with LDAC and AAC codecs
- 5 (LDAC Mode) 8 (ANC On) 10 hours (ANC Off) listening on one single charge. That’s quite impressive for a little battery!
- IPX4 waterproof rating gives you splashproof protection from water.
- The charging case has up to 50 hours of use, which means you can fully charge the earbuds 5 times before reaching for a plug.
Should you not wish to block out the world, well, 98% of it, you can enable transparency mode which allows you to listen to your music as well as chat to someone in a room with you. I found that I could hear people around me quite well even whilst having music playing on a low volume.
Another thing I’d like to add is how tough the earbuds and charging case is. I’m a bit of a butterfingers at times and tend to drop smaller things such as the earbud charging case, or the earbuds themselves. I dropped the case from chest height onto a concrete floor, not only did the case stay closed, but there is not a mark on it. I’ve also dropped one of the earbuds, and again, there isn’t a mark on it. That’s quite impressive to me.
Design and Functionality
As mentioned, the Soundcore Space A40 earbuds use a typical design. But that’s not a bad thing. Why change something that is already good?
The sound quality of the actual earbuds is actually pretty good. I would rate them as one of the better sets of earbuds I have used, but not the best. But at the cost of canceling out more noise, this is kind of to be expected.

However, they do have a “Game Mode” which reduces latency at the cost of sound quality. A number of times I’d put them in and would enable game mode because of the tap controls as I put them in my ears. I would then be questioning why the sound quality had gotten so poor.
Of course, I would then check the app (more below) and see “Game Mode Enabled”. As soon as I disabled this, the sound quality was much, much better.
Connection and Software
The Soundcore Space A40 uses Bluetooth 5.2 which is pretty good as this is one of the most recent revisions of Bluetooth, with 5.3 being the only newer version at the time of writing.
The headphones automatically connect to your previous device with ease. For example, your mobile phone that they are paired to will just see them once you open the little charging case.
Should you need to repair, or pair to a new device, then there is a little button on the exterior of the charging case.

As you can see the Space A40 earbuds use the Soundcore app just like recent earbuds, headphones, and speakers I have reviewed.
The app is actually very good and I find it very simple to use and also a great companion for the Soundcore audio hardware. It allows you to tweak settings such as the equaliser on your audio hardware, change the tap control settings, and more.
Conclusions
To conclude, the Soundcore Space A40 is actually not a bad bit of hardware for the price you pay. At the time of writing, they cost around £90. However, for that price, I have used better-sounding earbuds that don’t block quite as much noise. It’s entirely down to user preference if you want better sound or block more noise.
In my honest opinion, during my walks to work it’s quite nice to be able to block out a lot of the sound from the traffic, so for me, I’d probably choose these over better-sounding buds.
I give the Soundcore Space A40 a Controller Nerds score of 8/10.
