At its core is a 50 mm dynamic driver with a W-shaped ceramic-reinforced polymer diaphragm and a Multi-Layer Distributed (MLD) system — delivering piston-like driver behavior across the full audible range (5 Hz–44,500 Hz). The SR7000’s “Dragon Scale” acoustic prism uses advanced metamaterial design to tame internal resonances and standing waves, enabling a surprisingly wide, open-feeling soundstage despite the closed-back construction. With a moderately easy-to-drive 55 Ω impedance and high sensitivity, it pairs well with both portable players and desktop DAC\/amp rigs. Combine that with plush memory-foam earpads, a lightweight 390 g build, and a dual-cable set (standard and balanced) in a premium carrying case — and you get a headphone equally at home in critical listening sessions, home studio work, or everyday music enjoyment.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"align-center\"\u003e\u003cstrong\u003e\u003cspan class=\"color-light\"\u003eWe do not ship Aune products to the EU, please contact a distributor in your region.\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"Aune","offers":[{"title":"Default Title","offer_id":55711158501750,"sku":"AUNE-SR7000","price":510.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0361\/2681\/files\/61pT09OvXPL._AC_UF1000_1000_QL80_DpWeblab.jpg?v=1749110283"}],"url":"https:\/\/spartanmusic.co.uk\/collections\/tubes-hifi.oembed","provider":"Spartan Music","version":"1.0","type":"link"}
