Build quality

Build quality is not bad, considering the price. It has a simple and elegant appearance in black.


There is a strong shiny feeling in some areas, which may divide your taste. It has a tendency to get fingerprints a little easily.

Connection quality

I tested it by connecting it to a Cayin N6II/E02 with aptX. Excellent connection quality for the price range. I haven't been in crowded places, so I don't know, but it's stable in my home. Distance tolerance is excellent, and the connection is seamless and intact even at a distance of about 5 meters. The communication was consistent and undisturbed even when interrupted by shielding. It seems to be quite stable.


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



The operation interface is touch-based.

UGREEN HiTune X5 Frequency Response (RAW)


Sound quality description

The UGREEN Hitune X5 has a very well-balanced, neutral, mild V-shaped sound. However, the low frequencies have a lot of weight and depth, and especially if you usually prefer monitor-type sounds with weak low frequencies, the presence can sound quite strong, so if you don't like heavy low frequencies, it may seem like it has a very strong thump. For me, this is about as good as it gets, but it would be too strong for older people who tend to hear the high frequencies attenuated. The mids are mostly flat, and the lows are carefully tuned and raised, with a slight slope from the lower midrange.


The mids are slightly recessed, making them slightly darker, and vocals sound a bit distant. By retracting the midrange a bit, a sense of depth is reproduced, and a slight emphasis on three-dimensionality is felt. Given the strength of the low frequencies, the sound is suitable for young people. Overall, the model delivers a fairly well-balanced sound for this price, and I was personally quite impressed with it.


Frankly speaking, after listening to the X5, my opinion of UGREEN is nudging up.


The following review was tested on a FiiO M15 with an aptX connection.

Sound quality general comment
  • Original sound fidelity: A-
  • Recommendation: S
  • Personal preference: S+


I can unquestionably recommend the UGREEN X5 as one of the best completely wireless earphones you can get in this price range. Its perfection is high and the stereo imaging is near perfect. The overall measurements also remain at a good level, which shows that the sound quality of completely wireless earphones is definitely surpassing that of wired earphones in the same price range.


The recommendation for these earphones will depend on how old you are and how much you like heavy bass frequencies.


--Do you like low frequency? Then this is definitely a good model for you.


--If so, this is definitely a good model for you. However, if you have a weakness for models with strong low frequency, or are over 50 years old? If you are over 50 years old, then the low frequency of this model may be too strong for you.

General comment

The UGREEN Hitune X5 is a model that I can't believe is available at this price. It has a fairly well-balanced V-shaped sound, with very little of the unnaturalness in the midrange that is often associated with this type of sound. While there is an emphasis on the dynamism that is characteristic of the V-shaped, the sound shows a skillful sense of balance in trying to keep the whole thing well within the range of not deviating too far from neutral, which clearly indicates the presence of a skilled sound engineer.
