It delivers a punchy, full-bodied sound with rich detail, combining the layering and imaging often associated with multi-driver designs with the tonal density and natural warmth of a dynamic driver, all within a cohesive and unified presentation.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eVisceral sound\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eASTRU moves beyond passive listening into a presentation that feels tangible. The sound is dense, immersive, and engaging—delivering realistic impact, natural weight, and a sense of physical presence across the frequency range.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eUnique to the core\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eAt the center of ASTRU is a high-performance single dynamic driver built with a multilayer metal-coated composite diaphragm. This architecture is engineered for control, refinement, and consistency, preserving the integrity of the signal from source to ear.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eMultilayer coating\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe diaphragm dome is constructed through a multi-stage process. An outer gold coating is applied in 80 ultra-thin layers using physical vacuum DC magnetron sputtering over 48 hours, followed by a titanium layer bonded to a PEEK dome base. This structure contributes to smoother high frequencies, improved extension, and more natural transient response.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eSound that breathes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eA rear vent equalizes pressure between the driver’s back cavity and the exterior environment. This allows unrestricted low-frequency excursion for extended sub-bass and bass output below 200 Hz, while continuously relieving ear canal pressure for fatigue-free long-term listening.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003ePure titanium shell\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe housing is CNC-machined from a single block of pure titanium into a one-piece construction. It is then refined through a multi-stage electroplating process to achieve a smooth satin finish that enhances comfort. Each matched pair of shells requires up to seven days of processing.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eEthereal comfort\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eBuilding on the ergonomic foundations of earlier designs, ASTRU follows the natural contours of the ear with precision. The refined shell geometry eliminates pressure points and hotspots, allowing the earphones to disappear during extended listening sessions.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eHigh-quality cable\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe included cable measures 3.9 ft (1.2 m) and uses silver-plated Linear Crystal Oxygen-Free Copper (LC-OFC) conductors in a dual-strand configuration with 161 conductors per strand. It is insulated in SoftFlex PVC for flexibility and comfort, with CNC-anodized aluminum housings and a gold-plated 4.4 mm balanced termination for reliable, high-quality signal transmission.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSingle dynamic driver design\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFull titanium one-piece CNC-machined shell\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMultilayer gold and titanium-coated diaphragm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRear vented acoustic system for extended bass and comfort\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eErgonomic shell geometry for long listening sessions\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSilver-plated LC-OFC cable with 4.4 mm balanced termination\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDriver type: Dynamic\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDriver size: 0.39 in (10 mm)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSensitivity: 111 dB SPL\/mW at 1 kHz\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eImpedance: 32 Ω\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFrequency range: 5 Hz – 35 kHz\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTotal harmonic distortion: \u0026lt;0.1% at 1 kHz\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInput connector: 2-pin\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWeight: 0.47 oz (13.4 g)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eWhat’s included\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eASTRU in-ear monitors\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDetachable 3.9 ft (1.2 m) cable with 4.4 mm balanced termination\u003c\/li\u003e\n\u003cli\u003ePouch and envelope\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLiquid silicone ear tips\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Meze Audio","offers":[{"title":"Default Title","offer_id":47403196416236,"sku":"APS-1291-1","price":899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0225\/2721\/3642\/files\/apos-audio-meze-audio-earphone-in-ear-monitor-iem-meze-audio-astru-iems-1227872657.jpg?v=1774007588","url":"https:\/\/apos.audio\/products\/meze-audio-astru-iems","provider":"Apos","version":"1.0","type":"link"}
