What do you prioritize when choosing earphones?
Depending on the person, there are various factors such as sound quality, size, noise-canceling effectiveness, and other functional features.
The earphones reviewed here, 『Edifier TO-U2 mini』, are perfect for those who prioritize design and weight, featuring a cute design and ultra-lightweight build.
In this review, I will thoroughly examine what makes Edifier‘s cute, lightweight earphones, 『Edifier TO-U2 mini』, so appealing, as well as where they might fall short!

Edifier TO-U2 mini Design and Appearance

Mr. GadgetAnyway, it has exceptional design!
The icons are way too cute!
Also, as you can see, it adopts an open-ear design, which is relatively rare among truly wireless earbuds.
Actual Usability of the Edifier TO-U2 mini
Sound Quality…Mid-range is decent. Bass is a bit weak…
The mid and high ranges come through fairly well, but I felt the bass is a bit weak.
It is more of a mid-heavy sound profile rather than a V-shaped one.
Looking at it by frequency range, the mid-range is not bad and has quite a bit of presence.
As for the low frequencies, even when focusing on them, their presence is weak, and I felt a lack of both weight and depth.
Mr. GadgetBeing an open-ear (earbud) design, this may be somewhat inevitable.
When I pressed the earbuds fairly firmly into my ears, I was able to feel some weight in the bass.
The high frequencies also did not feel very extended, resulting in a somewhat lightweight sound.
Because the bass and treble lack solidity, the overall balance feels somewhat off, and a lack of depth is noticeable.
The sound is a bit cheap; while I wouldn’t call the sound quality bad, it falls short compared to earphones in the same price range…
Mr. GadgetHowever, unless you have exceptionally refined ears, I think this is at a level where regular users won’t find anything to complain about!
Supports SBC Only
The “Edifier TO-U2 mini” only supports the SBC codec.
Mr. GadgetPersonally, I would have liked it to support aptX for Android smartphones
and AAC for iPhones…
It’s not that SBC itself is inherently bad, and in terms of specs, it is said to be capable of CD-quality sound.
However, in practical terms, it falls short of newer standards in areas like sound quality and low latency.
| Codec | Features |
|---|---|
| SBC | The most standard codec. Basically supported by all devices. Sound quality and latency are standard, neither particularly good nor bad. |
| AAC | Often used in Apple products such as the iPhone. Generally supported on Android 8.0 and above as well. Lower latency and higher sound quality than SBC. |
| aptX | Primarily adopted on Android devices. 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 high-resolution equivalent sound playback. Slightly higher latency than aptX. |
| aptX Adaptive | A codec that stabilizes aptX HD and reduces latency. By switching 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. Generally supported on Android 8.0 and above as well. Switchable between three sound quality modes, such as Sound Quality Priority and Connection Priority modes. Higher latency than SBC. |
Ms. GadgetWhile codecs aren’t the only factor determining sound quality and low latency, considering that they can be a major factor in sound quality, relying solely on SBC might feel a bit underwhelming…

Noise Cancellation… Not included (Call noise cancellation only)
The “Edifier TO-U2 mini” does not feature Active Noise Cancellation (commonly known as ANC).
It does feature call noise cancellation, which filters out surrounding ambient noise during phone calls to deliver clear audio to the other party.
Mr. GadgetSince earbuds equipped with active noise cancellation have become mainstream recently, the lack of it is a bit unfortunate…
Ambient Sound Mode… Not included
Just like active noise cancellation, this is also not included.
Mr. GadgetThat’s a shame…
Ultra-lightweight! Incredibly light!
These earbuds are incredibly lightweight.
While standard earbuds typically weigh around 6 to 7g per side, and even lightweight models usually hover around 5g, the “Edifier TO-U2 mini” blows them away at just 3.5g.
Moreover, even when including the charging case—which typically weighs around 60 to 80g for standard earbuds—the “Edifier TO-U2 mini” achieves a mind-boggling light weight of 39.6g.
Ms. GadgetThis is a welcome feature for anyone who wants to keep their luggage as light as possible!
Outstanding Design!
You can check the status of the earbuds using the cute icons displayed on the case’s OLED display.
The icons are not displayed constantly; they appear when certain actions are performed (such as “placing the earbuds in the charging case”) and turn off after a few seconds.
Mr. GadgetThis is the kind of unique earbud I’ve been waiting for!!!
Supports Low Latency Mode!
A low latency mode that helps reduce audio delay can be enabled.
Conclusion
An earphone that focuses heavily on design. That is the Edifier TO-U2 mini.
As you can tell from reading this far, these earphones are characterized above all by being lightweight and featuring an OLED display.
To be frank, if you are pursuing cost performance, I recommend a different pair of earphones.
As I mentioned at the outset, these earphones are strongly recommended for those who care about earphone weight and prioritize design!
Mr. GadgetIt is quite rare to find an earphone with such a clear-cut concept, isn’t it? (Laughs)
I like them much better than some awkwardly half-baked earphones! (Laughs)
I felt that the sound quality is not bad either, making them a great option as a lightweight earphone with outstanding design that you can use normally!
