Customer Review Summary
Introduction to Meze Audio Astru
Released in March 2026, the Meze Audio Astru are closed-back in-ear headphones designed with a focus on sound fidelity and build quality. Positioned at £792, these monitors aim to deliver precise audio reproduction supported by robust construction materials and versatile connectivity options. This review examines the Astru’s technical specifications and design to understand how they stand in a competitive audiophile market.
Design and Build Quality
The Astru feature a titanium housing equipped with galvanised nickel wax protection. This combination ensures a durable yet lightweight structure, weighing only 13.4 grams. Such materials are typically chosen for their strength and resistance to corrosion, suggesting a long lifespan and resilience under daily use conditions.
A dark gray finish lends the headphones a modern and understated aesthetic. The cable is detachable with a smooth texture, extending 1.2 metres, and terminates in a 4.4 mm balanced mini-jack with an included 3.5 mm adapter. This setup offers flexibility for connection to various playback devices, from portable players to professional audio equipment.
Included in the package are five pairs of ear tips (ranging from XS to XL), which permits a personalised fit for different ear canal sizes, enhancing comfort and acoustic isolation. The protective bag and artificial leather cover add convenience for transport and storage, safeguarding the headphones when not in use.

- Driver: 10 mm dynamic unit design
- Impedance: 32 Ohms, suitable for use with a wide range of devices without the need for amplification
- Frequency Response: 5 Hz to 35,000 Hz, offering an expansive range beyond standard audiophile expectations, particularly extending well into sub-bass and ultrahigh frequencies

Closed-Back System Benefits
The closed-back design of the Astru limits sound leakage and external noise intrusion, which is essential for focused listening or use in noisy environments. This ensures the integrity of the audio experience is maintained without distraction, with an emphasis on delivering accurate bass and midrange response.
Connector and Cable Details
The use of a detachable cable with a 4.4 mm balanced mini-jack enhances compatibility with both consumer and professional audio sources. This, paired with the 3.5 mm adapter, supports flexibility in everyday use. The cable’s smooth finish and manageable length improve handling and reduce tangling, contributing to an overall hassle-free experience.
Practical Considerations
At 13.4 grams, the lightweight construction combined with multiple ear tip sizes suggests the Astru will offer extended comfort even during prolonged listening sessions. The comprehensive accessory set, including protective gear, further supports portability and care.
The £792 price point positions the Meze Audio Astru as a premium product, targeted at audiophiles seeking technical precision and refined build quality in an in-ear format. The inclusion of advanced materials and balanced connectivity options underlines this positioning.
Conclusion
The Meze Audio Astru present a technically compelling package with an emphasis on extended frequency response, minimal distortion, and durable craftsmanship. Their closed-back design provides effective noise isolation, and the detachable cable system adds versatility. While no subjective listening impressions are included here, the specifications point towards a pair of in-ear monitors engineered for discerning users demanding high fidelity and robust build integrity.
