{"product_id":"obravo-hamt-1-headphones","title":"oBravo HAMT-1 Headphones","description":" \nThe world first Coaxial two-way headphone design by an implementation of  AMT tweeter and Dynamic Neodymium driver to deliver a rich sound stage listening experience in the headphone market.\u003cbr\u003e\u003cbr\u003e\n\nThe term \"unique\" often pops up in reference to new products, but the company believes these two-way coaxial headphones justify the tag, due to their fully patented AMT driver technology.\u003cbr\u003e\u003cbr\u003e\n\nAMT stands for Air Motion Transformer - where the loudspeaker driver moves air using a folded diaphragm, built around a series of aluminium struts inside a \"high-intensity\" magnetic field.\u003cbr\u003e\u003cbr\u003e\n\n\nOnce the signal has passed through these struts, the diaphragm moves back and forth, (imagine an accordion's action), pumping air through the chambers.\u003cbr\u003e\u003cbr\u003e\n\nThis results in a dipole driver that oBravo claims to have an \"extraordinarily rapid response rate\", with the diaphragm covering less distance than a dynamic driver with a traditional cone.\u003cbr\u003e\u003cbr\u003e\n\noBravo also says that a standard 25mm AMT strip is comparable to a 20cm circular dynamic cone in terms of its functional driver area, with the aim of delivering a fully immersive experience.\u003cbr\u003e\u003cbr\u003e\n\nThe exterior of the HAMT-1s is built using a combination of aluminium, wood and leather. \u003cbr\u003e\u003cbr\u003e\n\nSpecification:\u003cbr\u003e\n•Frequency Response: 15Hz~45KHz\u003cbr\u003e\n•Tweeter: 40mm AMT Tweeter\u003cbr\u003e\n•Sensibility in dB\/1W\/1m: 105dB\n","brand":"oBravo","offers":[{"title":"oBravo HAMT-1 Headphones","offer_id":57409598882124,"sku":"OBRAVOHAMT1","price":1249.17,"currency_code":"GBP","in_stock":true},{"title":"oBravo Balanced Standard 4 pin 3.5m cable","offer_id":57422371062092,"sku":"OBRAVOBALSTAND4PIN3.5M","price":208.33,"currency_code":"GBP","in_stock":true},{"title":"oBravo Balanced Mini 2.5mm 4 pin 1.2m cable","offer_id":57422371094860,"sku":"obravobalmini2.5mcable","price":166.67,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/oBravo-HAMT-1-headphones.jpg?v=1777489388","url":"https:\/\/www.stoneaudio.co.uk\/products\/obravo-hamt-1-headphones","provider":"Stone Audio","version":"1.0","type":"link"}
