The Power of Bone Conduction

Bone conduction redefines audio with cutting-edge technology. No in-ear insertion—sound transmits directly through skull bones, keeping you aware of surroundings for safety. Lightweight and secure, it stays stable during workouts without discomfort. Clear sound, ergonomic design, perfect for commuting, sports, and the office. A smart blend of innovation and comfort, unlocking a freer way to listen.

Acoustic Architecture

True excellent sound quality never comes from the solitary efforts of a single driver, but rather the harmonious coexistence of different drivers, such as dynamic, moving iron, and electrostatic drivers, which collide to create an auditory feast beyond imagination. The dynamic driver brings a warm and mellow sound, carrying the fullness and atmosphere of low frequencies. Every dive of the low frequencies is steady and powerful, restoring the most authentic warmth of the sound. The moving iron driver is precise and delicate, unlocking the clarity and resolution of mid-to-high frequencies. The breath of vocals and the overtones of instruments are clearly distinguishable, bidding farewell to blurriness and turbidity. The electrostatic driver brings out every detail, fully extending the high frequencies, creating an ethereal and transparent sound that is not harsh, allowing every sound detail to be gently captured.

An immersive sound experience

In 2018, UM launched Mirage Titanium Power, and after six years, the brand has developed a new product-UM Stardust. Stardust introduces groundbreaking innovations in design, driver configuration, and tuning. The raw titanium surface remains unpolished, creating a modern industrial aesthetic with a cosmic, stardust-like texture.
With a meticulously tuned hybrid dynamic and balanced armature driver setup, Stardust delivers an immersive sound experience. Embrace Stardust and join fellow music enthusiasts in an interstellar musical journey.

The UM Stardust is a high-performance hybrid in-ear monitor (IEM) featuring a 6-driver configuration with dual dynamic drivers and four balanced armature drivers for a well-balanced, immersive sound. Designed to deliver deep, impactful bass, warm mids, and crystal-clear highs, it provides an exceptional listening experience.

Crafted from aerospace-grade titanium using 3D metal printing, the Stardust offers lightweight durability, superior comfort, and excellent corrosion resistance. The earphones come with the UM Tunewire Custom Cable, ensuring optimal signal transmission. With its precision-tuned crossover system and modern industrial aesthetic, the UM Stardust is ideal for audiophiles seeking powerful yet refined sound quality.

Unleashing Deep, Powerful Bass Capturing Every Nuance

UM Stardust features an innovative dual dynamic driver and four balanced armature combinations, creating the ultimate harmony between low, mid, and high frequencies, redefining your auditory experience. The custom dual dynamic drivers are precisely tuned to deliver deep, impactful bass with exceptional tension, ensuring every drumbeat resonates straight to your core for an immersive, heart-pounding experience.
The four balanced armature drivers, meticulously divided across frequency ranges, reproduce mid and high frequencies with stunning accuracy and realism. Warm, natural vocals and crystal-clear instruments transport you to a live concert, allowing you to feel the true soul of every note.

Perfect Dynamic Balance in Harmony

With a high-precision crossover system, the dual dynamic drivers and four balanced armatures seamlessly integrate, delivering a crystal-clear and well-layered sound spectrum. Deep and impactful bass meets transparent mid and high frequencies, creating a rich, immersive full-range listening experience. Stardust, with its minimalist driver combination and unique tuning technology, exemplifies the perfect dynamic balance between the power of dynamic drivers and the precision of balanced armatures a true synergy of collaboration and refinement.

Titanium Metal Shell

Titanium, with a melting point of 1660±10°C, is crafted into UM Stardust using aerospace-grade 3D metal printing technology, incorporating a hollowed-out design. Through high-temperature laser sintering, titanium transforms from powder into a uniquely structured metallic earphone shell. Titanium offers strength comparable to steel while being significantly lighter. With a density of 4.54g/cm³, it is 43% lighter than steel, making UM Stardust both durable and lightweight. Its exceptional corrosion resistance protects against wear from skin secretions, ensuring long-lasting durability and ease of maintenance. Titanium’s biocompatibility inhibits bacterial growth, making it widely used in medical instruments.

The titanium material of UM Stardust embodies both subtle elegance and distinctive character, balancing stability and energy. Its lightweight, ergonomic design ensures a comfortable, skin-friendly fit, allowing for extended wear without fatigue.

UM Tunewire Custom Cable

The Tunewire Custom Cable is specially developed for the tuning of UM Stardust. The wire is made with 5N long-crystal high-purity oxygen-free copper and 5N long-crystal copper with silver plating, combined using the Litz Type 4S process to effectively reduce signal transmission loss. When paired with the UM Star-dust earphones, it provides a perfectly balanced synergy. The cable is available with 2.5mm, 3.5mm, or 4.4mm connectors.
