When choosing earphones, what is most important to you?
Sound quality, size, noise cancellation performance, and other functions – I think there are various points depending on the person.

This time, I will thoroughly review what is good and what is not so good about Edifier‘s cute and lightweight earphones 『Edifier TO-U2 mini』!

Also, as you can see, these are in-ear type earphones, which are rare among truly wireless earphones.

Actual Usage Experience of Edifier TO-U2 mini

Sound Quality… Mid-range is decent. Low-end is a bit weak…

The mid-range and high-range sounds are decent, but the low-end is a bit weak.
It’s not a bass-heavy type, but more of a balanced type.
Looking at each frequency range, the mid-range is good and has a good sense of impact.
The low-end is weak and lacks weight and depth even when focusing on it.

The high-range also doesn’t feel very extended and has a light feel.
The overall balance is a bit off and lacks depth.

Codec is only SBC

The 『Edifier TO-U2 mini』 only supports SBC.

SBC itself isn’t bad, and it’s said to be able to output CD-quality sound.
However, in reality, newer codecs have advantages in terms of sound quality and latency.

Codec	Features
SBC	The most standard codec. Basically, all devices support it. Sound quality and latency are neither good nor bad, but standard.
AAC	Often used in Apple products such as iPhones. Android 8.0 or later generally supports it. Better sound quality and lower latency than SBC.
aptX	Mainly adopted by Android. Better sound quality and lower latency than SBC and AAC.
aptX LL	LL stands for Low Latency. It has 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	A high-quality codec that supports high-resolution sound. It has slightly higher latency than aptX.
aptX Adaptive	A codec that stabilizes and lowers the latency of aptX HD. Changing from a fixed bit rate to a variable bit rate has made processing more stable and latency lower.
LDAC	A high-quality codec developed by Sony. The best sound quality among the ones introduced so far. Android 8.0 or later generally supports it. It has 3 sound quality modes: quality priority, connection priority, and balanced. Latency is higher than SBC.

Noise Cancellation… Not Included (Only Call Noise Cancellation)

The 『Edifier TO-U2 mini』 does not include active noise cancellation (so-called noise cancellation).
It includes call noise cancellation, which cancels out ambient noise during calls to deliver a clear voice to the other party.

Ambient Sound Mode… Not Included

This is also not included, just like active noise cancellation.

Ultra-Lightweight! Incredibly Light!

These earphones are incredibly light.
Most earphones weigh around 6-7g per ear, and even lightweight earphones weigh around 5g. However, the 『Edifier TO-U2 mini』 weighs only 3.5g per ear, which is overwhelming.
Also, considering the case, most earphones weigh around 60-80g including the case, but the 『Edifier TO-U2 mini』 weighs only 39.6g, which is a different dimension.

Outstanding Design!

The OLED display on the case allows you to check the earphone status with cute icons.

The icons don’t always appear; they appear when a certain action is performed (“putting the earphones in the charging case”, etc.) and disappear after a few seconds.

Also, as you can see, these are in-ear type earphones, which are rare among truly wireless earphones.

Summary

Design-focused to the extreme. That’s Edifier TO-U2 mini.

As you can see from reading this far, these earphones are particularly lightweight and have an OLED display.
If you’re looking for cost-performance, I recommend another earphone.
However, if you prioritize the weight of the earphones and design, I strongly recommend these earphones!

The sound quality isn’t bad either, and it’s a good choice as a lightweight, design-focused earphone.
