Meze Audio Astru

Meze Audio Astru In-ear monitors Designed for devoted music lovers who demand accuracy, realism, and fidelity, ASTRU combines advanced acoustic engineering with uncompromising titanium construction to deliver a listening experience that is visceral, immersive, and deeply musical. 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. 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 & 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: 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; High-Quality 4.4 mm Balanced Cable: Silver-plated LC-OFC conductors, 161 conductors per strand, SoftFlex PVC insulation, CNC anodised aluminium housings, and a gold-plated 4.4 mm balanced termination — optimised 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. 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: 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; This configuration achieves multi-driver performance, layered imaging, precise staging, and high resolution within a single, cohesive driver system. COMFORT, LONGEVITY & 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.

Cosmic. Artistic. In Romanian, “ASTRU” is defined as either a celestial body or an illustrious soul. Here, it means both – a fusion of immense gravity with artistic subtlety. A universe in the palm of your hand. A guide meant to illuminate your musical journey. FacebookShare on XLinkedInWhatsAppEmailCopy Link
