• Truthear Shio

• 3 pairs of Vocal silicone ear tips (S, M, L)
• Cable 
• Quality is very good, but ear hooks are really stiff.

Build Quality

• Slightly more heft than usual resin IEMs but feels way more sturdier.
• Has a premium matte finishing to it, and an aluminum faceplate. 

Fit

• Nozzle width is on the larger side, comparable to the Truthear Hexa, length is average.
  
• The stiff ear hooks from the cable causes a little pain after long hours of listening, as there is a force clamping on my ears, not sure if this problem will still persists in the future. But after mentioning this problem to a rep, the heat from a hairdryer can be used to change the shape of the ear hooks to a certain degree, hope this helps. 
• Other than the ear hook issue, the body of the IEM is a little on the bulky side, which may cause some discomfort if you have smaller ears. 

Tonality

• Neutral with sub bass boost.

Bass

• Sub bass is definitely more prominent, while mid bass can be a little lacking sometimes.
• Very well controlled with good rumble and depth.
• Bass impact scales very well with volume.
• The louder you listen to, the more impactful the bass sounds. 
• Texture and definition is quite good as well, with decently natural speed and decay. 
• However, it lacks a little bit of fullness and body to the bass.
• Quantity is on the tamer side compared to most IEMs I have heard.

Midrange

• Midrange is very clean, may be a little too lean for some. 
• Female vocals sound fantastic and clear, quite forward and engaging, perhaps a little shouty for some.
• Male vocals on the other end is a little thin and pulled back, lacking some fullness to it. 
• Note weight and density is a little thin on the lower end but average on the upper end.
• Instruments sound quite natural throughout the midrange overall.

Treble

• Treble is relaxing and laid back, lacking some sparkle.
• Lower and mid treble is generally relaxed and toned down from the upper midrange.
• Slight roll off in the upper treble section but it is not the worst, causing it the extension to be average and not very airy.
• However, there is some slight sibilance to me throughout the treble even though it is an overall smooth experience.
• Details in the treble is quite decent.

Technicalities

Resolution

• Resolution is good, not underwhelming at all but not the most resolving IEM in this price range. 

Soundstage

• Soundstage is decent, both the width and depth are quite wide/deep respectively.  

Imaging

• Imaging and accuracy is decent, I am able to tell where the instruments and vocals quite well from left/right but struggle a little in other directions.
• Gaming:
• Apex Legends: Similar situation, I'm able to judge the sound of footsteps and gunfire in terms of left and right really well but not other directions like top and bottom.

Separation

• Separation and layering is good, vocals popped out more than any other instruments while each individual instruments are decently separated.  

Comparison

Letshuoer X Gizaudio Galileo

• Bass: DZ4 has a better sub bass extension, causing it to sound more rumbly and deep but will somewhat covers up the mid bass at lower volumes. Galileo on the other hand has a much better mid bass texture and definition but lacks a little bit of the depth and rumble from sub bass.
• Midrange: Galileo excels in almost every aspect here for me. It is just more natural with the little bit of warmth, and less aggressive upper midrange in the Galileo is much smoother and textured to my ears.
• Treble: Both sets are quite relaxed but DZ4 excels a little bit more by having a little more air and extension.
• Technicalities: Galileo has a slight edge in terms of resolution and imaging but the DZ4 has a slightly wider and deeper soundstage.
• Overall, I would personally prefer the Galileo due to its more natural and smoother presentation. 

Conclusion

• Overall, I think that this is a good set that I can recommend if you're into:
• Unique driver configurations (3DD + 1PR in this case)
• Neutral tonality
• Engaging female vocals 
• Clean and natural midrange focused sets
• Definitely a good addition of a neutral/vocal set into the budget category!
