Hidizs MS5 Review – The Dark Angel

The new MS5 is powered by Hidizs new custom 10mm liquid silicone dynamic driver. This is a sandwich injection molding process. Its body is Kevlar with a thickness of only 0.03mm, surrounded by liquid silicone of 0.45mm. Kevlar has ultra-high elasticity, combined with extremely thin liquid silicone to form a dynamic drive with good elasticity, good transient, high sensitivity, and quick response. Moreover, the unique physical characteristics of Kevlar enable the internal losses generated by the dynamic drive to absorb vibration and reduce interference.

Combined with Hidizs’ new liquid silicone dynamic driver the MS5 is equipped with a total of 4 Denmark Sonion balanced armature drivers. The E50DT high-frequency composite driver, the dual 2389 mid-high frequency drivers, and the 17A003 low-frequency driver.

The solder joints inside the MS5 earphones use Hidizs exclusive compound material containing gold tin wire. Gold element is extremely stable and does not easy to be oxidized, which brings many advantages such as stable electronic signal transmission and durable components. It is only used for high-end products and also improves the fineness of the sound.

MS5’s cavity design features an upgraded “Hidizs Pneumatic Sound Tuning Filter™” replaceable technology. It comes standard with three different configurations of tuning filters. The waveform of the air vibration is adjusted by the pre-designed sound tube structure and the density of the tuning cotton. That is, you can feel a completely different sound style without changing products and tuning styles.

MS5 adopts a weight-saving one-piece aluminum alloy cavity design. At the beginning of modeling, the thickness and volume of the metal were reduced as much as possible to achieve a balance of strength and weight. By anodizing the surface of the aluminum alloy cavity, an aluminum oxide film is formed on the surface of the panel, which effectively improves the hardness of the surface of the cavity, makes the panel smoother, and reduces the residue of fingerprint marks. And it can reduce the harmonic resonance inside the earphone cavity, reduce distortion, and make the audio signal output cleaner and more stable.

MS5 sits well in the ears because of its ergonomic design.

The panel is still made of skin-friendly resin material, and the weight is further reduced through the hollowing process. And after multiple processes such as polishing and spraying, it presents the image of angel wings, like a messenger in the dark night, gazing at the night sky. The space between the panel and the cavity is a rose gold mesh panel, and the overall visual sense is very dazzling. The golden mesh panel can be seen through the hollow wings, which are calm, delicate, and profound.

The MS5’s cable has been upgraded compared to the previous model the MD4. A total of 504 6N single crystal copper silver-plated wires and 6N single crystal copper wires are mixed with 8 strands to form a tight braided wire. The outer skin of the wire insulation layer is made of black environmentally friendly PVC material, which is soft and shiny. The 3.5mm plug is made of gold-plated copper.

The cable looks awesome but it is on the heavy side, very heavy!

The MS5 storage box is made of high-quality PU leather, which is carefully crafted by leather craftsmen. Environmentally friendly and durable, waterproof and tough, and full of texture. Using high-quality double-head zipper, strong bite, smooth, and easy to pull. The leather is equipped with iron sheets, which are reinforced to prevent pressure and deformation, and the interior is supplemented with flannel, which is soft, protective, moisture-proof, and reliable.

What’s in the box


Hidizs MS5 Review

The difference between the treble and bass filters is audible but not so much between balanced and treble or balanced and bass, at least to my ears. I used the treble filter in my testings.

The Hidizs MS5 is an interesting in-ear monitor. From the very first listen, you notice that it has a unique, slightly warm, and impressively airy presentation. It has a wide and deep soundstage and it offers a precise sense of instrument layout. I must say that its technical prowess surprised me a lot.

It offers a slightly warm timbre with a good body. One of the major points that I liked about the tuning of the MS5 is its ability to stay relaxed no matter the genre. Of course, all of these positive points allow it to be a brilliant all-rounder in my opinion.


The bass goes deep, oh my. The sub-bass is full-bodied and has a meaty rumble without feeling too empowering with a well-controlled mid-bass performance. It has a fast solid attack, with a bit of a slow delay, just enough to emphasize the low notes while still having a distinct gap on each note.

Bass-heavy tracks sound impressive with the Hidizs MS5. Lows are well incorporated across the frequency spectrum sounding impactful and textured whilst being neither muddy nor bloated.

Don’t let the golden grill under the face plate fool you, MS5 is not an open-back design, just for the looks


The midrange is mostly even, with a good balance between the lower and upper midrange. Instruments sound natural on the Hidizs MS5, especially on how articulate and textured wind and string instruments are.

The violins, in particular, are presented in a warm and rich tonality. However, the piano did sound a bit thin in comparison. Nevertheless, the instruments blended well in harmony, giving an exceptional midrange presentation.

Vocals presence is excellent. With the midrange tuned a bit further forward than the bass, vocals, both male and female, still have pop, even in bass-heavy tracks. Vocal layering is transparent with the MS5 meaning overlapping vocals are clear and distinct.

The MS5’s treble tuning compliments the overall coloration of the IEM (tested with treble filters). Although the treble takes a back seat, it’s tuned to be neither dark nor bright with just enough presence to make the midrange shine also, at least to my ears.

The treble extends well with the MS5, enough to notice its presence and brilliance. Although there is a lack of sparkle, cymbals and acoustic guitar strums are sharp and crisp with a pleasant airy, and light presentation.

One thing they did well in the treble is its control. Higher frequency sounds natural with no harshness or sibilance felt, even in vocals hitting extended high notes. The MS5’s treble is tuned well enough to avoid fatigue in extended listening.

Technical Performance

The Hidizs MS5 has a very spacious and breathy presentation with a slightly warm, balanced signature. It offers excellent stereo imaging, it has a wide and deep soundstage with precise instrument separation. There is plenty of air between the instruments and it is quite easy to follow individual instruments on stage. The layering and the positioning of the instruments are clear and distinct. Additionally, the MS5 handles congestion well, thanks to its breathy presentation and coherent signature. The transients, on the other hand, are fast and agile. Overall, the MS5 has an excellent technical foundation and offers very good performance in this regard.

Hidizs MS5 Review 20


Hidizs MS5 is a carefully researched and designed product that offers an excellent unboxing experience with plenty of good-quality accessories. It boasts a robust build quality and beautiful design. It has a rather interesting and different tuning starting from the upper mids to the treble section which I find very pleasant and fun to listen to. The MS5 would be my dream IEM if it had less elevation on the bass region but I know I’m in the minority in this, you will probably love the end result.
