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 Stardust  earphones, it provides a perfectly balanced synergy.

The cable is available with 2.5mm, 3.5mm, or  4.4mm connectors.
