Anker Soundcore Life A3i Evaluation
Sound quality… Powerful bass is achieved
Equipped with a large 13mm driver and Anker’s unique BassUp technology.
Powerful and impactful bass can be enjoyed.
Supported codecs are a little disappointing
The supported codecs are SBC and AAC.
Mr. GadgetAlthough sound quality is not always greatly affected by codecs, it’s better to have more supported codecs.
There are more products available at this price range that support more codecs.
Please refer to the table below for the characteristics of each codec.
| Codec | Characteristics |
|---|---|
| SBC | The most standard codec. Basically, all devices support it. Sound quality and latency are standard, with no particular advantages or disadvantages. |
| AAC | Frequently used by Apple products. Android 8.0 or later generally supports it. Offers lower latency and higher sound quality than SBC. |
| aptX | Mainly adopted by Android. Offers lower latency and higher sound quality than SBC and AAC. |
| aptX LL | LL stands for Low Latency. It is even lower latency than aptX. Sound quality is the same as aptX, but latency is less than 0.04 seconds, achieving ultra-low latency. |
| aptX HD | Supports high-resolution equivalent sound quality. Has slightly higher latency than aptX. |
| aptX Adaptive | An aptX HD that is stabilized and has low latency. Changing from a fixed bit rate to a variable bit rate has made processing more stable and low latency possible. |
| LDAC | A super high-quality codec developed by Sony. It has the highest sound quality among those introduced so far. Android 8.0 or later generally supports it. Has higher latency than SBC. |
Please see this article for information about codecs and other truly wireless earbuds.

Compatible with Soundcore app
The “Soundcore Life Note 3S” is compatible with the Soundcore app.
Mr. GadgetPersonally, I like the Soundcore app more than the apps of other manufacturers.
Settings for game mode, sleep mode, and customizable equalizer
With the app, you can set game mode, sleep mode, customize the equalizer, and make various other settings.
Gaming mode reduces sound delay.
You can expect some reduction in latency, but since the supported codecs for the “Soundcore Life Note 3S” are SBC and AAC, it’s best not to expect too much.
Also, it emphasizes action sounds and footsteps during gaming, creating a more immersive experience.
Mr. GadgetIf you really care about low latency, you should buy earbuds that support aptX LL or other low-latency codecs.
Sleep mode plays relaxing healing sounds.
Noise canceling… Not supported
Not supported for active noise canceling.
Mr. GadgetIf you want noise canceling, there are plenty of affordable truly wireless earbuds available from other manufacturers.
Ambient sound mode… Not supported
Similar to noise canceling, it is not supported.
Playback time… Sufficient for commuting
The “Soundcore Life Note 3S” has a maximum playback time of 5 hours with a fully charged earbud and 35 hours with the included charging case. Also, a 10-minute charge provides approximately 1 hour of music playback.
Mr. GadgetThe earbuds themselves can play continuously for a maximum of 5 hours, so they will probably be sufficient for commuting.
However, “maximum” 5 hours, so if you use game mode, it will be shorter.
It may be a problem if you play games for a very long time.
Supports wireless charging!
The “Soundcore Life Note 3S” supports wireless charging.
Mr. GadgetMany smartphones now support battery sharing.
Although compatibility with standards and models varies, it’s a great advantage to be able to wirelessly charge your earbuds when you’re out and about if your smartphone has battery power!
Lightweight and in-ear type for comfortable wear
The “Soundcore Life Note 3S” weighs approximately 4.3g per earbud.
The weight of the earbuds is an important consideration if you plan to wear them for a long time, but 4.3g is quite light among truly wireless earbuds.
A major feature of the “Soundcore Life Note 3S” is that they are lightweight and comfortable to wear for long periods of time.
Also, if you dislike the pressure of canal-type earbuds, in-ear type is recommended.
Mr. GadgetLightweight and in-ear, so they are recommended for those who want to wear them for long periods of time!
However, as mentioned earlier, they only have a maximum battery life of 5 hours when the body is fully charged, so be careful about that.
Peace of mind with Anker quality
In recent years, the mainstream has become truly wireless earbuds. Various manufacturers are competing to release many products.
As the market for truly wireless earbuds has grown, there has been increasing chaos, with unknown Chinese manufacturers releasing products and products without PSE marks being sold.
In such a situation, the fact that they are manufactured by the well-known Anker is a major reassurance.
Mr. GadgetTruly wireless earbuds contain batteries.
We do not recommend using strange manufacturers that we do not know.
The fact that they come with a 18-month warranty + 6-month extension warranty for members is also a reassuring point.
Mr. GadgetBecause it is a well-known manufacturer, Anker has solid support.
When I previously had an Anker product fail, it was still within the warranty period, so I was able to have it replaced immediately!
Summary
Recommended for those who want relatively affordable in-ear type
Overall, the “Soundcore Life Note 3S” is a noteworthy point that it is relatively affordable and manufactured by Anker, especially considering that in-ear type earbuds are rare.
Also, being equipped with a large 13mm driver and Anker’s unique BassUp technology to achieve powerful bass is a major feature.
Frankly, if you’re okay with canal-type, there are more cost-effective products available from Anker itself. But if you’re particular about in-ear type, Anker at this price point is a big advantage.
It’s a shame that they don’t support noise canceling or multipoint connection, but these earbuds are recommended for those who want relatively affordable and reliable in-ear truly wireless earbuds.
