Real-World Usage
Sound Quality… Well-balanced, better than the price suggests
Overall, it is well-balanced, and I didn’t really feel the “don-shari” (V-shape) sound profile that Soundcore has been known for in the past. While it is slightly V-shaped, I feel it has a well-balanced sound across all frequencies.
Vocals come through clearly, so I especially recommend these for people who like pop music and J-POP! Conversely, those who prefer a strong V-shaped sound with emphasized bass and treble might find it a bit lacking. However, as I will mention later, you can tweak the sound itself to some extent using the app’s equalizer.
Also, it supports LDAC, allowing you to listen to high-resolution quality audio, and as I will detail later, the sound quality changes significantly.
LDAC Support!
Are you familiar with LDAC, the codec known for providing overwhelmingly better sound quality?
| Codec | Features |
|---|---|
| SBC | The most standard codec. Basically supported by all devices. Standard in terms of both sound quality and latency. |
| AAC | Commonly used in Apple products like the iPhone. Generally supported by Android 8.0 and above. Higher sound quality and lower latency than SBC. |
| aptX | Mainly used in Android. Lower latency and higher sound quality than SBC and AAC. |
| aptX LL | “LL” stands for Low Latency. Even lower latency than aptX. Sound quality is equivalent to aptX, but realizes ultra-low latency of less than 0.04 seconds. |
| aptX HD | Capable of high-resolution equivalent sound quality. Slightly more latency than aptX. |
| aptX Adaptive | A codec that stabilizes and reduces the latency of aptX HD. By switching from a fixed bit rate to a variable bit rate, processing is more stable, achieving lower latency. |
| LDAC | An ultra-high sound quality codec developed by Sony. The highest quality among those introduced so far. Generally supported by Android 8.0 and above. Can switch between 3 sound quality modes such as “Sound Quality Priority” and “Connection Priority”. Higher latency than SBC. |
We explain codecs and other information regarding wireless earbuds in this article.
Please note that iPhones do not support LDAC.
Most recent Android devices support it.
I tested LDAC with these earbuds, and the sound quality is quite different. Before testing, I thought it would be a difference that you’d only notice after carefully listening, but the difference is surprisingly large. In my estimation, the sound quality improves by about 1.8 levels. Especially in the treble and bass, the difference is clear, and I was surprised while listening!
However, please note that turning on LDAC shortens playback time and increases sound latency. You also won’t be able to use multipoint connection or gaming mode.
MisterGadgetWell, most other earbuds lose multipoint connection when LDAC is turned on, so it’s not just this model’s fault.
Noise Cancelling… Extremely effective for the price
The “Soundcore Space A40” is equipped with Anker’s new proprietary Ultra Noise Cancelling 2.0 technology. I felt it was quite advanced, as it can automatically adjust the strength of the noise cancellation according to the surrounding noise level.
The effectiveness is very good for this price, and I felt the cost performance was excellent. If you turn on noise cancellation and play music even on a train, you won’t really notice the surrounding noise. However, if you turn on only the noise cancellation without playing music and ride the train, you can still hear the train’s running noise to some extent.
Ms.gadgetI think it’s top-class among earbuds in the same price range!

Ambient Sound… Usable, but feels unnatural
When you switch the mode from noise cancelling to ambient sound, the change is extremely obvious. You will be surprised at how well you can hear your surroundings. However, high-pitched sounds are quite emphasized, so it doesn’t feel natural.
Compact yet super long battery life!
If there’s one standout feature of these earbuds, it’s the playback time, which is exceptionally long even among Anker earbuds. They can play up to 10 hours on a single charge, and up to 50 hours when using the included charging case. It’s insane for how compact they are.
MisterGadgetEven if you forget to charge them for a day, you’ll be fine!
Of course, if you use features like LDAC or noise cancellation, the playback time will be shorter, but even then, you won’t feel like you can’t get through your daily use on a single charge.
The Soundcore app and equalizer are incredibly easy to use!
You can adjust the earbud settings in the app like this.
You can also customize the touch controls.
MisterGadgetBeing able to customize down to the fine details is a nice point!
You also need to use the app to set other things like turning LDAC on/off, gaming mode to reduce latency, wind noise reduction, and touch sounds.
You can create your own custom equalizer settings, or select from presets.
Ms.gadgetAs you can see, there are many presets prepared. I have a very favorable impression that so many presets are properly provided!

Gaming Mode Support!
You can set a Gaming Mode to reduce latency. You can also theoretically turn on Gaming Mode even while using LDAC.
However, if you turn on Gaming Mode, you won’t be able to use features like the equalizer.
Multipoint connection is convenient!
The “Soundcore Space A40” supports multipoint, allowing it to connect to two Bluetooth devices simultaneously. Up to two devices, you don’t need to disconnect or reconnect. For example, you can respond to calls on your smartphone while watching YouTube on your tablet.
Ms.gadgetThis is very convenient!
Summary
The Soundcore Space A40 is a must-buy!
I bought mine during the Amazon Black Friday sale, so the price was under 10,000 yen! At this price, you can experience Anker’s noise-cancelling technology and it supports LDAC, so there is nothing to complain about. Of course, if you spend more money, there are earbuds with better sound quality or that are easier to use, but at this price, it’s rare to find earbuds this balanced. As for the battery, even though they are compact, they last 50 hours, which is far longer than other series from Soundcore, so not only do they have no downsides, they have nothing but upsides.
