Meze Audio introduces ASTRU: new flagship IEM,
delivering top-of-the-line performance from a single dynamic driver
Meze Audio introduces ASTRU, its new top-of-the-line single dynamic driver in-ear monitor, created for listeners who demand true high-end performance without crossing into flagship pricing territory. ASTRU embodies a focused philosophy: one driver, delivering a visceral, full- bodied sound that rivals the layering, imaging, and resolution typically associated with multi-driver designs.
DRIVER TECHNOLOGY
At the core of ASTRU is an advanced multilayer composite dynamic driver diaphragm,
engineered to balance speed, control, and musical weight. The diaphragm dome features over 80 ultra-thin layers of gold, applied during a 48-hour physical vacuum DC magnetron sputtering process, then bonded to a titanium layer and finally mounted on a PEEK base. This carefully tuned structure delivers fast transient response, smooth and extended treble, and the natural warmth and physical impact that dynamic drivers are celebrated for.
DESIGN
ASTRU’s housing reflects Meze Audio’s commitment to comfort and craftsmanship. ASTRU’s shell geometry has been painstakingly refined for improved long-term comfort. Each shell is CNC-machined from a single block of pure titanium, then refined through a multi-stage electroplating process to achieve a smooth satin finish. Each matched pair of shells requires up to seven days of precision processing, underscoring the attention to detail behind every unit.
ACCESORIES
The IEM is delivered as a complete, ready-to-use system, designed for high-end portable listening. It includes a premium balanced cable that features CNC-anodized aluminum hardware and a gold-plated 4.4 mm balanced termination. This ensures low resistance, signal purity, and long-term durability. A 4.4 mm to 3.5 mm adapter, five sizes of ear tips (XS–XL), and two carry solutions - a protective pouch and a soft PU leather envelope - make ASTRU equally suitable for portable use or dedicated listening setups.
SOUND
With ASTRU, Meze Audio redefines what a single dynamic driver IEM can achieve: rich, detailed, and immersive sound, crafted with uncompromising materials and thoughtful engineering, at a price point designed to remain accessible to serious listeners.
