After testing the Anker Soundcore P40i, I found it to be an earphone with very few flaws that I can recommend to everyone, thanks to its inclusion of Anker’s proprietary Ultra Noise Canceling 2.0 technology and convenient multi-point connection support.
It supports practically everything you could want, including noise cancellation and ambient sound mode, as well as multi-point, game mode, and a companion app.
I was genuinely surprised while reviewing it to think that this is priced under 10,000 yen.
This is an earphone I highly recommend for anyone looking for earphones under 10,000 yen or those who want highly functional earphones.

Mr. GadgetI purchased the navy version this time.

Actual Usability
Sound Quality… Overall Focus on Impact
Anker Soundcore P40i Sound Quality Verdict
- Sound quality that will satisfy the average person
- Punchy, bass-heavy sound typical of Anker
- Highs feel a bit sharp
- Mids can be hard to notice due to the assertive bass and highs
- Adjustable via the app equalizer
Definitely strong on impact!
- This evaluation is entirely based on personal subjective opinion.
When I first used the ‘Anker Soundcore P40i’, the first thing I noticed was the strong impact of the bass.
The bass emphasizes punch and weight.
So, conversely speaking, it lacks depth and delicacy to some extent.
Mr. GadgetI think it pairs well with rock and upbeat music genres.
Well, for ballads, there are times when I wish for a bit more finesse (laughs).
However, it’s not that depth and delicacy are completely absent, so there isn’t any specific genre that it struggles with tremendously.
Also, the highs have a slightly sharp feel.
It’s not piercing to the ears, but they don’t feel particularly expansive.
The mids are somewhat hard to notice due to the assertive bass and highs.
Mr. GadgetRest assured, you can change this somewhat with the equalizer function introduced later!
Supported codecs are pretty average for this price range.
The supported codecs are SBC and AAC.
Mr. GadgetWhile I would love to see support for more codecs, for under 10,000 yen, this is about what you would expect.
Refer here for the characteristics of each codec.
| Codec | Characteristics |
|---|---|
| SBC | The most standard codec. Basically supported by all devices. Sound quality and latency are standard, for better or worse. |
| AAC | commonly used in Apple products like the iPhone. Android also basically supports it on version 8.0 or higher. Less latency and higher sound quality than SBC. |
| aptX | Mainly adopted in Android. Lower latency and higher sound quality than SBC and AAC. |
| aptX LL | LL stands for Low Latency. Features even lower latency than aptX. Sound quality is on par with aptX, but achieves ultra-low latency of under 0.04 seconds. |
| aptX HD | Capable of playing high-resolution equivalent sound quality. Slightly more latency than aptX. |
| aptX Adaptive | A codec that stabilizes and reduces latency for aptX HD. By changing from a fixed bitrate to a variable bitrate, processing is more stable and lower latency is achieved. |
| LDAC | An ultra-high sound quality codec developed by Sony. The highest sound quality among those introduced here. Android basically supports it on version 8.0 or higher. Switchable between 3 sound quality modes such as Sound Quality Priority and Connection Priority modes. Higher latency than SBC. |
We explain codecs and other wireless earphone specifications in this article.

Fit is quite good


Since 5 ear tips—XS, S, M, L, and XL—are included, most people should be able to find a size that fits them.
Mr. GadgetThe S size fit me just right.
Ms. GadgetEar tips directly relate to the fit, so they’re important!
Having this kind of selection is a welcome point!

Noise cancellation adjusts according to surrounding noise

The ‘Anker Soundcore P40i’ utilizes Anker’s proprietary technology, Ultra Noise Canceling 2.0.
This technology automatically adjusts the intensity of the noise cancellation according to the surrounding noise level.
Mr. GadgetIf noise cancellation is stronger than necessary, that in itself can lead to an unnatural feeling.
This feature helps prevent such issues.
Ms. GadgetIt’s a high level of performance for under 10,000 yen!
Occasionally unstable operation
Regarding this noise-canceling feature, in my experience, it occasionally becomes unstable.
For example, there are times when noise cancellation doesn’t work at all even though it’s set to noise-canceling mode.
Mr. GadgetTurning noise cancellation off once and turning it back on fixes it, but it’s a bit of a hassle.

Ambient Sound Mode… Usable, but not natural
To be clear, it doesn’t feel natural.
I think there are many other earphones in the same price range that do a more natural job.
However, surrounding sounds are indeed audible despite being unnatural, so I feel it’s adequate for hearing train announcements and the like.
Mr. GadgetThe sensation of sounds being picked up from the outside via microphones is very strong.
Battery… Simply put, amazing
The playback times for the ‘Anker Soundcore P40i’ are as follows.
・Normal Mode: Up to 12 hours (earphones only) / Up to 60 hours (with charging case)
・Noise Canceling Mode: Up to 10 hours (earphones only) / Up to 50 hours (with charging case)
・Calls: Up to 7 hours (earphones only) / Up to 35 hours (with charging case)
Mr. GadgetIt’s super long! Amazing!
It’s so long that it would have been unthinkable a while ago!
Ms. GadgetI’m thoroughly satisfied if it lasts this long even when using noise cancellation!
Supports Multi-point!

The ‘Anker Soundcore P40i’ supports multi-point and can connect to two Bluetooth devices simultaneously.
Since you don’t need to disconnect and reconnect for up to two devices, you can, for example, watch YouTube on a tablet while answering an incoming call on your smartphone.
Ms. GadgetThis is very convenient!

Comprehensive App Features!
The Soundcore app is extremely well-equipped.
Details for the noise cancellation and multi-point features introduced so far can be configured from this app.
Customize to your preferred sound with Equalizer & Rich Sound Effects

You can tweak the equalizer and choose your preferred sound effects from the app like this.
Mr. GadgetThere are many types of sound effects, so you are sure to find one that suits you!
Types of Sound Effects

Configurable to Game & Movie Modes



Game mode and movie mode are also provided and can be selected from the app.
Mr. GadgetSwitching to movie mode suppresses the bass and emphasizes mid-to-high frequencies.
It also creates a reverberant feel.
Supports Google Fast Pair!


As shown, the ‘Anker Soundcore P40i’ supports Google Fast Pair, which is convenient on Android smartphones and other devices.
Mr. GadgetBeing able to immediately check the specific remaining battery percentage in the notification panel is extremely convenient!
Ms. GadgetBy the way, this is a feature completely irrelevant to iPhone users.

Doubles as a smartphone stand



By lifting the part marked PHONESTAND in the photo above, you can also use it as a smartphone stand.
Mr. GadgetIt has unexpected stability and high practicality.
I think this kind of interesting concept is wonderful!
Comes with an 18-month + 6-month warranty

The ‘Anker Soundcore P40i’ comes with an 18-month warranty plus an additional 6-month member-exclusive warranty.
Ms. GadgetHaving a proper warranty like this gives you peace of mind.
