{"product_id":"mezeaudioastru","title":"Meze Audio Astru In-Ear Headphones, Titanium","description":"\u003cp\u003eThe Meze Audio Astru is a high-end in-ear headphone (IEM) with a housing machined from a single block of pure titanium and a dynamic 10 mm driver.\u003c\/p\u003e\u003cp\u003eIt's Meze's flagship among single dynamic-driver in-ears – small, refined and surprisingly grown-up in sound. Instead of stacking multiple drivers, Meze relies on one carefully developed transducer and a housing that dislikes resonance.\u003c\/p\u003e\u003ch2\u003eWhy the Astru?\u003c\/h2\u003e\u003cp\u003eAt its core sits a dynamic 10 mm driver with a multi-layer composite diaphragm – a PEEK dome with 80 wafer-thin layers of gold and a titanium coating. The housing is CNC-machined from a single block of pure titanium and electroplated in several stages: extremely rigid, light and low in resonance. The detachable 2-pin cable (silver-plated LC-OFC) terminates in a balanced 4.4 mm connector – a 4.4-to-3.5 mm adapter is included, so it plays from any source.\u003c\/p\u003e\u003ch2\u003eWhat you hear\u003c\/h2\u003e\u003cp\u003eA smooth, richly coloured and balanced sound with plenty of calm and control. The Astru never pushes itself forward; it delivers detail cleanly and without harshness – the kind of tuning you don't tire of even after hours. On the balanced 4.4 mm output of a good player, it steps up another notch in dynamics and soundstage.\u003c\/p\u003e\u003ch3\u003eWho is the Astru for?\u003c\/h3\u003e\u003cp\u003eFor anyone who wants a high-quality in-ear for home and on the move and values a natural, effortless sound. Plain talk: the Astru comes with a balanced 4.4 mm cable – on a normal 3.5 mm jack you'll need the included adapter, and you unlock its full potential from a source with a balanced output. If you're after the big, airy soundstage of an open over-ear, look at the 105 AER or 109 PRO instead.\u003c\/p\u003e\u003ch2\u003eOur verdict\u003c\/h2\u003e\u003cp\u003eThe Astru is a grown-up, wonderfully built in-ear that shows how far a single dynamic driver can carry you – pure titanium included. Which ear-tip size and which source suit you best is something we'll work out together at HD Zürisee in Wädenswil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the trade press says:\u003c\/strong\u003e «For anyone who enjoys a smooth, rich, well-balanced tuning, it feels like an easy recommendation.» – \u003ca href=\"https:\/\/headfonics.com\/meze-audio-astru-review\/\" target=\"_blank\" rel=\"noopener\"\u003eHeadfonics\u003c\/a\u003e, 2026 (Award Score 8.6).\u003c\/p\u003e\u003ch2\u003eTechnical data\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eType:\u003c\/strong\u003e in-ear headphone (IEM), closed-back\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDriver:\u003c\/strong\u003e dynamic, 10 mm (multi-layer composite diaphragm with titanium coating)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eFrequency range:\u003c\/strong\u003e 5 Hz – 35 kHz\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eImpedance:\u003c\/strong\u003e 32 Ω\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 111 dB SPL\/mW at 1 kHz\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDistortion (THD):\u003c\/strong\u003e \u0026lt; 0.1% at 1 kHz\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 13.4 g\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMaterials:\u003c\/strong\u003e housing in pure titanium (CNC, one-piece, satin-finished)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eConnector:\u003c\/strong\u003e 2-pin (0.78 mm), detachable cable; 4.4 mm balanced plug\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCable:\u003c\/strong\u003e 1.2 m, silver-plated LC-OFC, dual-strand\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eScope of delivery:\u003c\/strong\u003e Astru in-ear, 4.4 mm cable, 4.4-to-3.5 mm adapter, 5 pairs of silicone ear tips (XS\/S\/M\/L\/XL), hard case, PU-leather pouch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eWhy a housing made of pure titanium?\u003c\/h3\u003e\u003cp\u003eTitanium is exceptionally rigid and low in resonance. A one-piece machined titanium housing suppresses unwanted self-resonance and lets the 10 mm driver work more cleanly – you hear that as a clear, uncoloured reproduction. It's also lightweight and remarkably durable.\u003c\/p\u003e\u003ch3\u003eWhat does the 4.4 mm balanced connector mean – does it fit my device?\u003c\/h3\u003e\u003cp\u003eThe included cable terminates in a balanced 4.4 mm plug, as found on many better players and DAC\/amps. An adapter is included for standard 3.5 mm jacks. The Astru plays out its full potential on a genuine balanced output.\u003c\/p\u003e\u003ch3\u003eIs the Astru also suitable for on the go?\u003c\/h3\u003e\u003cp\u003eYes. As a closed in-ear it isolates well from the outside and sits securely thanks to the five ear-tip sizes. At 13.4 g it's feather-light. For maximum sound quality on the move, a small DAC\/amp with a balanced output is recommended.\u003c\/p\u003e\u003ch3\u003eWhy buy the Meze Audio Astru at HD Zürisee?\u003c\/h3\u003e\u003cp\u003eBecause fit and source make the difference.
