Package contents

There is no shortage of accessories. The package contains the following:


  • UGREEN HiTune T2
  • Charging case
  • USB Type-C cable
  • Manual






The manual is printed in color; it's not as fancy as HiTune's, but it's of good quality for this price range.


Build quality

It has an AirPods-like texture and the build quality is good for the price.





The housing part is a bit large, so it may be difficult for some people to fit it in their ears. The housing is a little large, so it may be difficult for some people to fit it in their ears. You need to twist it in until you feel a sense of pressure to get a stable fit.


If the fit is not good, the low frequency range tends to drop out and it is easy for them to fall off, so you need to place them in your ears carefully.


In my case, when I wore them normally with the usual light twisting motion, I felt that the amount of audible low frequency was insufficient compared to the measured value.


So I tried various ways to improve it, and found that I could get a relatively good sense of low-frequency volume if I fixed them by twisting them into the ear canal while pulling on the ear rings, so this method may be better.




Connection quality

I tested it by connecting it to a Cayin N6II/E02 with AAC. The quality of the connection is excellent for the price range. I haven't been in crowded places, so I don't know, but it's stable in the home. Distance tolerance is excellent, and the connection is seamless and intact even at a distance of about 5 meters. I could hear the music stably without any interruption in communication even with a barrier between us.


There may be a small amount of white noise, but most people probably won't notice it.

Sound quality

The Hitune T2 has a slightly warm neutral sound. Although the characteristics are called "soft", in reality, the lower midrange tends to be stronger than the highs, and the lows are not as overtly strong as the mids. As a result, there is a good sense of focus on the midrange, so many people will think that it is almost neutral or kamaboko in impression.


In particular, the low frequency range is easily affected by the fit, so it is even easier to hear the fish paste in this model, which is somewhat unstable in terms of fit.

Sound quality general comment
  • Original sound fidelity: B
  • Recommendation: B+
  • Personal preference: B+


In terms of sound quality, the biggest negative point of the UGREEN HiTune T2 might be that it is too much affected by the fit.


However, because of its well-balanced sound quality that is slightly low-frequency, it doesn't seem to break down even with slight changes in fit, making it relatively versatile. And if the fit is a little shallow and the low frequency range is not produced, the overall balance may be better.


The fact that it is easy to change the impression depending on the wearing feeling is an interesting point for me personally, but that is why it is difficult to evaluate it.


Sound quality features


  • Good balance
  • Warm and pleasant to listen to
  • Vocals are easy to hear
  • Relatively natural texture
  • Mild


  • Too much low frequency variation due to unstable fit
  • Lack of high frequency extension

General comment

The UGREEN HiTune T2 is a completely wireless earphone with a sound that combines a moderate sense of detail with a warm and comfortable mildness. The downside is that the fit is a bit unsteady, and the low frequency range changes a lot depending on the fit. Wireless charging support is convenient.
