Meze Audio / ASTRU Dynamic Driver Monitor Earphones

＜＜August 2026 New Product！＞＞"ASTRU" is a new-generation in-ear monitor featuring a full-titanium body and a high-performance single dynamic driver.

■ Full-Titanium One-Piece Housing
・Machined from a solid block of pure titanium using precision CNC milling, the housing achieves a remarkable balance of lightweight design (weighing just 13.4g) and exceptional durability. The synergy between titanium’s inherent vibration-damping properties and the meticulously engineered internal structure effectively eliminates unwanted resonance. This results in a silent, pitch-black background against which every single note emerges with vivid clarity and three-dimensional depth.

■ Satin Finish Exuding the Elegance of Fine Craftsmanship
・The left and right shells of the ASTRU undergo a luxurious manufacturing process that takes up to seven days to complete. The signature satin finish, achieved through a multi-layer electrolytic process, softly reflects light to create a sophisticated presence, harmonizing the functional beauty of a precision instrument with the aesthetic appeal of a fine craft.

■ Natural Musical Expression via a Single Dynamic Driver
・The ASTRU employs a single dynamic driver configuration. Because a single diaphragm handles the entire frequency range, it achieves phase coherence and a seamless, natural flow of sound that multi-driver setups cannot replicate. The ability to seamlessly render the raw resonance of instruments, the subtle fluctuations of a vocalist's breath, and the atmosphere of the recording studio is a unique strength of the single-diaphragm design.

■ Multi-Layer Coating
・The driver's dome features a titanium layer applied over a PEEK substrate, followed by an 80-layer ultra-thin gold coating created over 48 hours using DC magnetron sputtering technology. This advanced multi-layer structure enhances the smoothness and extension of high-frequency reproduction while achieving a more natural and delicate transient response, richly rendering every detail of the music. ■ Electroplated Nickel Wax Guard
・This wax guard is precision-etched from nickel and electroplated to beautifully complement the titanium nozzle. It prevents the acoustic filter from clogging, thereby extending the product's lifespan. It combines functionality and durability with a distinctive design that is instantly recognizable as Meze.

■ A Lively, Breathable Sound
・Vents on the back of the housing optimize pressure control between the driver's rear cavity and the outside environment. This ensures the smoothest possible driver movement, delivering overwhelming extension and fullness in the low frequencies (down to 200Hz). Simultaneously, continuous pressure relief prevents ear fatigue, ensuring comfort even during extended listening sessions.

■ Exceptional Fit from a Precision-Machined Titanium Chassis
・Building upon the ergonomic designs perfected in the "ALBA" and "ADVAR" models, we have further refined the shell shape for long-lasting comfort. ASTRU’s greatest appeal lies in a fit so comfortable, you might forget you are even wearing them.

■ Premium Cable Developed Specifically for ASTRU
・The included 1.2m cable utilizes silver-plated LC-OFC conductors; a dual-strand structure comprising 161 individual conductors ensures superior signal transmission. The SoftFlex PVC jacket offers a pleasant tactile feel while minimizing touch noise. It features a gold-plated 4.4mm balanced plug, unlocking the full performance potential of high-end portable DAPs. Our commitment to eliminating signal transmission loss extends to every detail of the cable.

■ High Resolution and Expansive Soundstage
・ASTRU achieves a perfect balance between high resolution—capturing even the finest nuances—and rich dynamics that fully convey the vitality of the music. Deep, impactful bass that remains tight and controlled; highs that offer both delicacy and an open, extended quality; and a vast, three-dimensional soundstage worthy of the "ASTRU" name—all combine to create an immersive experience that makes it feel as though the performance space itself is unfolding right before your eyes.
