Meze ASTRU In-Ear Monitors

Clarity Beyond Sound

ASTRU is more than an IEM, it is a statement piece. A full-titanium body, a single high-performance dynamic driver, and a precisely tuned acoustic architecture work seamlessly together to deliver the layering, imaging, and resolution typically associated with multi-driver designs, along with the tonal density and natural warmth only a single dynamic driver can offer. Simplicity raised to the highest level of performance.

Natural and Engaging

The sound signature is full-bodied, natural, and engaging: a rich, neutral tuning with realistic timbre, excellent resolution and detail retrieval, and strong dynamics and texture across the entire frequency range from a tight, impactful low end to transparent, extended highs that reveal fine musical detail without causing fatigue.

Design and Craftsmanship

ASTRU's chassis builds on the ergonomic foundations of ALBA and ADVAR, further refined for improved long-term comfort. Each unit is CNC-machined from a single block of pure titanium, with multilayer electroplating to achieve a signature satin finish. Processing one matched pair of shells requires up to seven days

Acoustic Engineering

At the heart of ASTRU is a 10 mm dynamic driver featuring an advanced multilayer metal-coated composite diaphragm, which results from a meticulous, multi-stage manufacturing process. This configuration achieves multi-driver performance, layered imaging, precise staging, and high resolution within a single, cohesive driver system

Comfort, Longevity, and Serviceability

ASTRU is engineered for extended, fatigue-free listening sessions. Its titanium construction ensures long-term durability and resistance to wear, while the modular cable connection (2-Pin) and included accessories support long-term ownership and ease of maintenance.

Function Built In

Full-Titanium One-Piece Housing: CNC-machined for precision fit, durability, and a lightweight feel at just 13.4g (0.47 oz)

Electroplated Satin Finish: Multilayer electroplating process delivers a refined, premium aesthetic.

Electroplated Nickel Wax Guard: Built-in protection without compromising sound transparency.

Flagship Accessories

High-Quality 4.4 mm Balanced Cable: Silver-plated LC-OFC conductors, 161 conductors per strand, SoftFlex PVC insulation, CNC-anodized aluminum housings, and a gold-plated 4.4 mm balanced termination — optimized for signal purity, low resistance, and compatibility with high-end portable sources.

Included Accessories: 4.4 mm to 3.5 mm adapter, five pairs of liquid silicone ear tips (XS, S, M, L, XL), hard pouch, and PU leather envelope for everyday carry.

Cohesive Driver Design

Gold-Coated Outer Dome: 80 ultra-thin layers of gold applied via physical vacuum DC magnetron sputtering over a 48-hour process, ensuring unmatched consistency and controlled resonance.

Titanium + PEEK Dome Construction: A titanium layer bonded to a PEEK dome base balances stiffness, transient speed, and resonance control.

Precision Magnetic Architecture: A vented backplate, inner and outer ring magnets, and a front magnetic spacer work in concert for optimal driver excursion and dynamic linearity.
