Bloom's Take The Meze Audio ASTRU delivers a refined take on the single dynamic driver formula, focusing on cohesion, tonal density, and an effortlessly musical presentation. Its tuning leans warm and full-bodied, with impactful, well-controlled bass, natural mids, and smooth, non-fatiguing treble that keeps the sound engaging without pushing into harshness. Rather than chasing extreme detail or clinical precision, ASTRU emphasizes balance and immersion, creating a sound that feels rich, spacious, and easy to enjoy across genres. Paired with its beautifully machined titanium shell and comfort-focused design, it’s a thoughtfully executed IEM that prioritizes long-term listening and a deeply satisfying sonic experience. |
Clarity Beyond Sound
Embark on a journey beyond listening into a real where music becomes palpable. Natural and powerful, ASTRU's sound is dense and immersive, creating a realistic, impactful all-encompassing presentation. ASTRU delivers a punchy, full-bodied sound, combining the layering and imaging associated with multi-driver IEMs with the tonal density and warmth dynamic drivers provide.
Unique to the Core
ASTRU is powered by a high-performance single dynamic driver featuring a multi-layer metal-coated composite diaphragm, engineered for exceptional control and refinement.
The diaphragm dome consists of an outer gold coating applied in 80 ultra-thin layers via physical vacuum DC magnetron sputtering, 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.
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, while continuously relieving ear canal pressure for fatigue-free long-term listening.
Pure 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.
Ethereal 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. The shell geometry has been refined even further: every curve finished to perfection, every surface optimized for the kind of long-term comfort that makes the shell disappear from awareness.
Features and Accessories
High-Quality Cable
The included 3.9ft cable features silver-plated Linear Crystal Oxygen-Free Copper 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 4.4mm balanced termination.
Adaptable
The package also includes a female 4.4mm to male 3.5mm adapter, enabling compatibility with a wide range of DAPS and amplifiers.
Liquid Silicone Ear Tips
To fully experience the detail and bass response, achieving a proper seal is essential. ASTRU includes five pairs of custom-made liquid silicone ear tips, designed for superior comfort and effective passive noise isolation. Available in XS, S, M, L, and XL sizes.
Built to Protect, Made to Match
Precisely etched from nickel and then electroplated to complement the titanium nozzle, the wax guard protects the acoustic filter from clogging, helping extend its lifespan. Functional, durable, and unmistakably Meze, it's a subtle detail that quietly safeguards every listening session.
Pouch and Envelope
To suit different moments in your journey, ASTRU arrives with two pouches: a sturdy pouch for secure storage and travel, and a softer PU leather envelope for a lighter, everyday carry.
