This time, we would like to introduce the truly wireless earbuds “Soundcore Life Note 3S” by Anker.
These earbuds are characterized by powerful bass and lightweight & in-ear design.
Considering that in-ear earbuds are rare, the fact that they are manufactured by Anker at a relatively affordable price is a noteworthy point.

It’s a shame that they don’t support noise canceling or multipoint connection, but these earbuds are recommended for those who dislike canal-type earbuds and those who want to use earbuds for long periods of time.

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. Gadget

Although 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.

CodecCharacteristics
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.
Characteristics of each codec

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. Gadget

Personally, 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. Gadget

If 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. Gadget

If 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. Gadget

The 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. Gadget

Many 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.

Q&A
What are in-ear type earbuds?

In-ear type earbuds are worn by inserting the body directly into the ear canal. The tip is shaped to fit the ear, and no other parts, such as ear tips, are required. They are less constricting and more comfortable to wear than canal-type earbuds, but have lower sound isolation and are more prone to sound leakage.

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. Gadget

Lightweight 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. Gadget

Truly 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. Gadget

Because 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.
