What do you prioritize when choosing earphones?
I think everyone has different points of focus, such as sound quality, size, effectiveness of noise cancellation, or other functionalities.
The earphones I am reviewing this time, the “Edifier TO-U2 mini“, are perfect for those who prioritize design and weight, featuring a cute design and being ultra-lightweight.
In this article, I will conduct a thorough review of what makes the Edifier‘s cute, lightweight “Edifier TO-U2 mini“ good, and where it falls short!
- OLED display on case can show icons
- Cute, cohesive design
- Ultra-lightweight!
- Equipped with noise cancellation for calls
- Equipped with low-latency mode
- No active noise cancellation
- No ambient sound mode
- Codec is SBC only

While it supports noise cancellation for calls, it does not support active noise cancellation, which is what is commonly referred to as “noise canceling.”
Mr.GadgetsIt does not support active noise cancellation, ambient sound mode, or multipoint, which are increasingly considered important…
Please note that there is no dedicated app either.
I explain in detail how to choose earphones, what IPX means, and Bluetooth versions in this article.

In any case, it has excellent design! The icons are just too cute!
Also, as you can see, it is an earbud-style (open-ear) design, which is in the minority among true wireless earphones.
Actual Usage Feel of the Edifier TO-U2 mini
Sound Quality…Mid-range is decent. Bass might be a bit weak…
The mid-range and high-range are okay, but I felt the bass was a bit weak.
It’s more of a mid-heavy sound profile than a V-shaped one, I suppose.
Looking at it by frequency range, the mid-range isn’t bad and feels quite impactful.
The bass range lacks presence, and even when I tried listening intently, I felt it lacked both weight and depth.
Mr.GadgetsSince it’s an earbud-style design, perhaps that’s somewhat unavoidable.
When I pressed the earphones into my ears a bit firmly, I was able to feel some weight in the bass.
I also felt that the high-range didn’t have much extension, resulting in a somewhat light-sounding audio.
Since the bass and treble aren’t solid, the overall sound feels slightly unbalanced and lacks depth.
It sounds a bit cheap, and it wouldn’t be accurate to say the sound quality is bad, but it pales in comparison to earphones in the same price range…
However, honestly, unless you have extremely discerning ears, I don’t think you’d be dissatisfied with using them normally!
Codec is SBC only
The “Edifier TO-U2 mini” only supports SBC.
Mr.GadgetsPersonally, I would have liked it to at least support aptX for Android phones and AAC for iPhones…
It’s not that SBC itself is bad; in terms of specs, it is said to be capable of CD-quality sound.
However, as a practical matter, it is inferior to newer standards in terms of sound quality and latency.
| Codec | Features |
|---|---|
| SBC | The most standard codec. Basically all devices support it. Sound quality and latency are standard, neither good nor bad. |
| AAC | Commonly used in Apple products like the iPhone. Android 8.0 and above also generally support it. Less latency and higher sound quality than SBC. |
| aptX | Mainly adopted in Android. Less 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 quality playback. Slightly more latency than aptX. |
| aptX Adaptive | A codec that stabilizes and reduces latency for aptX HD. By changing from a fixed bit rate to a variable bit rate, processing is more stable, achieving low latency. |
| LDAC | An ultra-high-quality codec developed by Sony. The highest sound quality among those introduced so far. Android 8.0 and above generally support it. Can switch between 3 types of sound quality modes, such as sound quality priority and connection priority modes. Latency is higher than SBC. |
Ms.GadgetsWhile the codec isn’t the only thing that determines sound quality or low latency, considering it is one major factor in determining sound quality, only having SBC might be a bit lacking…
I explain more about codecs and other wireless earphone information in this article.
Noise Cancellation… Not included (only noise cancellation for calls)
The “Edifier TO-U2 mini” does not come with active noise cancellation (so-called noise canceling).
It is equipped with noise cancellation for calls, which cancels out surrounding noise during calls to deliver clear audio to the other party.
Mr.GadgetsSince earphones equipped with active noise cancellation have become mainstream recently, it’s a bit painful that it’s not included…
Ambient Sound Mode… Not included
Like active noise cancellation, this is also not included.
It’s unfortunate…
Ultra-lightweight! Extremely light!
These earphones are extremely light.
While ordinary earphones are around 6-7g per side, and even earphones called “light” are often around 5g, the “Edifier TO-U2 mini” overwhelms them at 3.5g.
Also, even considering the case, while ordinary earphone cases are around 60-80g, the “Edifier TO-U2 mini” is 39.6g, a different dimension of lightness.
Ms.GadgetsThis is a welcome point for those who don’t want to make their luggage too heavy!
Excellent design!
You can grasp the status of the earphones with the cute icons displayed on the case’s OLED display.
Icons are not displayed all the time, but are displayed when a certain action is performed (e.g., “placing the earphones in the charging case”) and disappear after a few seconds.
Mr.GadgetsI’ve been waiting for unique earphones like this!!!
Supports low-latency mode!
A low-latency mode that can suppress lag can be set.
Summary
Earphones specialized in design. That is the Edifier TO-U2 mini.
As you can tell from reading this far, these earphones are characterized by being lightweight and having an OLED display.
If you are looking for cost-performance, I would frankly recommend other earphones.
As I mentioned at the beginning, I can strongly recommend these earphones to those who care about earphone weight and design!
Mr.GadgetsIt’s not often you find earphones with such a clear concept, is it? (laughs)
I actually like them better than weird, half-baked earphones! (laughs)
The sound quality isn’t bad either, and I felt it was a good option as a lightweight earphone with excellent design that can be used normally!
