Hidizs New Custom Liquid Silicon Dynamic Driver - Soft Hymn
The MS5 is equipped with Hidizs' new custom 10mm liquid silicon dynamic driver, which uses a sandwich injection molding process. The diaphragm is made of just 0.03mm thick Kevlar, surrounded by 0.45mm of liquid silicon. Kevlar has ultra-high elasticity, and combined with the ultra-thin liquid silicone, it forms a dynamic driver with excellent elasticity, outstanding transient response, high sensitivity, and fast reaction. Furthermore, the unique physical properties of Kevlar allow internal losses generated by the dynamic driver to be absorbed by vibrations, reducing interference; this significantly decreases audio glitches and delivers a more natural and softer sound.
Danish Sonion 4 Balanced Armature Drivers - Singing Hymns Loudly
The liquid silicon dynamic driver of the MS5 is paired with Danish Sonion balanced armature drivers, known for their reliable Nordic industrial quality and performance. The MS5 is equipped with a total of four balanced armature drivers. For ultra-high frequencies, the top-of-the-line E50DT high-frequency hybrid driver is used, expanding the soundstage with smooth, transparent, natural sound and excellent resolution with bright tones. The mid-high frequencies are driven by the mid-high 2389 driver, providing rich and emotionally detailed sound. Low frequencies use the 17A003 driver, producing powerful, controlled, and well-defined bass. The combination of one dynamic driver and four balanced armature drivers creates an angelic chorus with clear sound, full dynamics, and fatigue-free long listening sessions.


Hidizs' Unique Soldering Process - Perfectly Capturing Every Detail
The solder joints inside the MS5 earphones use Hidiz's proprietary composite material, which includes gold-tin wire. The element gold is extremely stable and resistant to oxidation, providing many benefits such as stable electrical signal transmission and component durability. It is used only in high-end products and improves the fineness of the sound.
Replaceable “Hidizs Pneumatic Sound Tuning Filter™”
The MS5's cavity design features upgraded "Hidizs Pneumatic Sound Tuning Filter™" replaceable technology. Three different configurations of tuning filters are standard. The air vibration waveform is adjusted by the pre-designed sound tube structure and the density of the tuning cotton. This means you can experience a completely different sound style without changing your product or tuning style. Balanced - Rose Gold: Hidiz's signature style, suitable for pop and folk. High Frequency - Quiet Silver: Improves smoothness, suitable for ACG and classical Low Frequency - Charm Red: Full of energy, suitable for rock and heavy metal.


Dark Angel Sculpture - Artwork that walks the world
The MS5 features a one-piece aluminum alloy cavity design that reduces weight. Initially, we made the metal thickness and volume as thin as possible to balance 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, making the panel smoother and reducing the remaining fingerprint marks. It can also reduce harmonic resonance inside the earphone cavity, reduce distortion, and make the audio signal output cleaner and more stable. The panel is made of a resin material that is gentle on the skin, and the hollow processing makes it even lighter. Through processes such as polishing and spraying, it expresses the image of angel wings staring up at the night sky like a messenger in the dark. 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 panels peeking out from the hollow wings give it a gentle, delicate, yet profound feel.
6N Single-Crystal Copper Silver-Plated Wire Mixed with 8 Strands of 6N Single-Crystal Copper Wire
A good pair of earphones cannot be separated from a good earphone cable—they complement each other. The MS5 cable has been upgraded. A total of 504 strands are mixed from 6N single-crystal copper silver-plated wire and 8 strands of 6N single-crystal copper wire, forming a dense braided cable. The pure and delicate sound of single-crystal copper and the lively, dynamic sound of single-crystal copper silver-plated wire elevate the MS5 to new heights. The outer layer of the wire insulation is made from soft, glossy black, eco-friendly PVC material. The 3.5mm plug is copper-gold plated, showing the MS5’s grandeur and meticulous attention to detail.


Exquisite Earphone Storage Case
The MS5 storage case uses high-quality PU leather, carefully crafted by skilled artisans. It is eco-friendly, durable, waterproof, and robust, with a rich texture. A high-quality double-headed zipper is used, providing strong grip and smooth, easy operation. Reinforced iron sheets are equipped in the leather to prevent pressure and deformation, while the interior is lined with soft flannel, providing protection, moisture resistance, and high reliability.
New 0.78mm 2-Pin Detachable Cable Design
The MS5 features a detachable 0.78mm 2-pin design, offering greater flexibility. This allows users to pair the MS5 with other cables to explore different styles and experience a variety of sounds. The pin design has been updated with a new detail: the original plastic curved pin base has been reshaped into an angel’s armor, bringing the Dark Angel to life in a more vibrant and interesting way.


Human-Like Ear Structure Design, Comfortable Fit
Designed for secure portability. Made with premium, waterproof, and sustainable polyurethane leather, and reinforced with leather and magnets with iron, preventing deformation while providing maximum protection. Handcrafted by skilled artisans.
Hi-Res Certified
Hi-Res was first proposed by Sony, and later, the Consumer Technology Association (CTA), Digital Entertainment Group (DEG), recording engineering professionals, and major record companies jointly unified the Hi-Res audio definition standards. It is now a certification mark essential for high-end audio equipment.
