Disclaimer: This Hidizs MS3 IEM was sponsored by Hidizs official. I was given this MS3 for free in exchange for my honest review about this IEM. I am not the professional reviewer, but I'll do my best to share my opinion on this IEM for everyone who reading this review.

Overall review (with balanced ear-tips + balanced tuning filter)
Building: Aviation Aluminum Alloy Integral Molding Shell
Fitting: Pretty good – very light IEM and comfortable wearing
Tone: Energetic U-shaped sound signature
Sound quality: Decent
Soundstage: Average


Package (Box)
The package is quite large in size, but proper with the items inside. When open the box you’ll see a pair of IEM (MS3) lay inside, then the next cover is for the eartips which come in 3 sizes (S, M, L) and 3 types (balance, bass, and vocal), and you’ll see the tuning filter at bottom right which is red, and silver (the rose gold one was already in the IEM). The last layer in the box is warranty card and carry magnet (leather) pouch where Sharkfin cable lies inside.





Building quality
The body was made from Aviation Aluminum Alloy integrated together which gives the strength, durability, and very light to the IEM at the same time. The shell is matted black which gives you the good feeling when touch it and not slippery, and more importantly hard to leave the scratch mark on it. I, personally, like the feeling of this matted surface very much (more than silvery-mirror shell).




Fitting
The IEM was not too small or too big into my ears. The size was perfect. When I inserted the IEM in my ears in lies comfortably with very light. There are 2 vents can be seen on the IEM which can prevent overpressure in your ear canal and makes you feel comfort while listening to music. In the sound isolation part it’s still not that good for me (depended on the eartips use too).



Cable “shark fin”
The cable is Oxygen-free Copper Multi-conductor comes with 4-wire-braided. The cable is soft and easy to use. There is a reason why this cable was called “Sharkfin” it’s because the 2-pin side was made into the shape of sharkfin (clear colorless), I just noticed that after a few days later lol. You can choose the plug for the IEM whether 3.5mm or 4.4mm plug before purchasing.




SOUND
The sound profile the system I used to test this pair of IEM is:
Desktop DAC: SMSL-SU9
Desktop Amp: xDuoo TA-20 (Vaccuum tube is 12AT7 x2)
IEM: Hidizs MS3 with balance eartips & Rose gold (balance) nozzle
Favorite tone: Personally, I quite like the Harman-tuning, but I also prefer the balance with bass boost tuning so the review could be biased from my preference here too.

Bass (4.2/5)
The bass quantity was good amount, clean note with some of impact. The subbass and midbass are dominant over upperbass. The bass speed was fast cold tone. Not bloated to mid or high frequency.

Mid (4.5/5)
In the lower mid, the drum part was very well-tuned. It got impactful on drum kick, snare or even tom. It has lively sound with clear note. If you like the drum sound, I bet you’ll love it. The guitar sound and timbre are good, not thin sounding at all. I’m really into the mid frequency of this MS3.

Vocal (3.8/5)
The male vocal is good with lush character. By the same time, the female vocal was quite forward even without hiss sound, but some people might feel a bit too spicy in the female vocal or mid-high frequency. The vocal image was clean but not that crystal clear. Overall I’m quite satisfied with the vocal part.

Treble (4/5)
Treble is sparkle with good extension but not too bright, the edge of the note is smooth and safe for your ears, not too forward and not too spicy. For me I think the treble part was carefully tuned to not to be too exaggerated.

Sound quality (3.5/5)
The sound quality is decent to the price, not better than expected and not bad. The note is not sharp or precise that much but it worth the price point.

Nozzle:
RED nozzle: You’ll get more bass quantity from this nozzle but not the quality, the mid is recessed, and the treble became more relaxed (less spicy).
SILVER nozzle: From what I can noticed, the bass quantity is the same, but the treble frequency became a little brighter, and gain some more sparkles and extension

Summary – The MS3 is one of the best all-rounders in its price bracket. If you like the bass sound and the drum part (but not into kind of basshead) without any recessed frequency (not the V-shape type). The MS3 is the right choice in the price bracket, because there’s 3 types of eartips and 3 kinds of tuning filter so you can modify the sound a bit into your style, plus the original cable is already good sounding. If you’re basshead and into the V-shaped person I think the other IEM would do the job than MS3
