Meze Astru – Dynamic Driver In-Ear Monitors

ONE IS ALL YOU NEED

ASTRU is more than an in-ear monitor; it is a statement piece: full-titanium, visceral sound, single dynamic. Simplicity raised to the highest level of performance.

It delivers a punchy, full-bodied, and rich, detailed sound – combining the layering and imaging associated with multi-driver IEMs with the tonal density and natural warmth dynamic drivers provide, all within a cohesive, unified presentation.

VISCERAL SOUND

Embark on a journey beyond listening into a realm where music becomes palpable. Natural and powerful, its sound is dense, immersive, and engaging, creating a realistic, impactful, and all-encompassing presentation.

ASTRU is powered by a high-performance single dynamic driver featuring a multilayer metal-coated composite diaphragm, engineered for exceptional control and refinement.ASTRU is powered by a high-performance single dynamic driver featuring a multilayer metal-coated composite diaphragm, engineered for exceptional control and refinement.

MULTILAYER COATINGMULTILAYER COATING

The diaphragm dome consists of an outer gold coating applied in 80 ultra-thin layers via physical vacuum DC magnetron sputtering over a 48-hour process, followed by a titanium layer bonded to a PEEK dome base. This multi-stage architecture delivers smoother high frequencies, greater extension, and more natural transient response.The diaphragm dome consists of an outer gold coating applied in 80 ultra-thin layers via physical vacuum DC magnetron sputtering over a 48-hour process, followed by a titanium layer bonded to a PEEK dome base.

SOUND THAT BREATHES

The rear vent equalizes pressure between the driver’s back cavity and the exterior, allowing unrestricted low-frequency driver excursion for extended sub-bass and bass output (below 200 Hz), while continuously relieving ear canal pressure for fatigue-free, long-term listening.The rear vent equalizes pressure between the driver’s back cavity and the exterior, allowing unrestricted low-frequency driver excursion for extended sub-bass and bass output (below 200 Hz), while continuously relieving ear canal pressure for fatigue-free, long-term listening.

PURE TITANIUM SHELLPURE TITANIUM SHELL

Lightweight yet exceptionally strong, the IEM housing is intricately CNC-machined from a single block of pure titanium into a one-piece construction, then refined through a multi-stage electroplating process to achieve a smooth satin finish that enhances wearing comfort. One matched pair of shells requires up to 7 days of processing.Lightweight yet exceptionally strong, the IEM housing is intricately CNC-machined from a single block of pure titanium into a one-piece construction, then refined through a multi-stage electroplating process to achieve a smooth satin finish that enhances wearing comfort.

ETHEREAL COMFORTETHEREAL COMFORT

Building on the ergonomic foundations set by the ADVAR and the ALBA, ASTRU maps to the natural contours of your ear with unprecedented precision – no pressure, no hotspots, only you and the music.

HIGH-QUALITY CABLE

The included 1.2 m (3.9 ft) cable features silver-plated Linear Crystal Oxygen-Free Copper (LC-OFC) conductors arranged in a dual-strand configuration, with 161 individual conductors per strand. Insulated in SoftFlex PVC for enhanced comfort and flexibility, the cable incorporates CNC-anodized aluminum housings and a gold-plated 4.4 mm balanced termination.

The construction is optimized for low resistance, signal integrity, long-term durability, and seamless compatibility with high-end portable sources.

ADAPTABLE

The package also includes a female 4.4 mm to male 3.5 mm adapter, enabling compatibility with a wide range of DAPs and headphone amplifiers.The package also includes a female 4.4 mm to male 3.5 mm adapter, enabling compatibility with a wide range of DAPs and headphone amplifiers.

LIQUID SILICONE EAR TIPSLIQUID SILICONE EAR TIPS

To fully experience the intended sound tuning, detail, and bass response, achieving a proper seal is essential. ASTRU includes five pairs of custom-made liquid silicone ear tips, engineered specifically to match its acoustic design. Using alternative ear tips may alter the sound signature and affect the intended tuning. Available in XS, S, M, L, and XL sizes.To fully experience the intended sound tuning, detail, and bass response, achieving a proper seal is essential.
