(FIIO Elastic System): A proprietary elastic assistance system designed by adding a new deformation vector to a planar film to increase the movement of the driver, allowing the diaphragm to build the elastic force to counteract internal stress\n• The JT7 has a high sensitivity of 92dB\/mW due to the powerful magnetic field generated by high-performance bi-directional neodymium iron boron magnets These magnets provide robust and sufficient driving force to planar drivers, bringing out a large and rich sound even from small output audio devices\u003c\/div\u003e","brand":"FiiO","offers":[{"title":"Default Title","offer_id":57193557360905,"sku":null,"price":25500.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0696\/8469\/1209\/files\/product_image_1_59870e73-a275-4212-9108-770f4aabcf5a.jpg?v=1783724582","url":"https:\/\/youplus-eu.myshopify.com\/es\/products\/fiio-jt7-gold-fio-jt7-g-headphones-open-type-flat-drive-type-gold","provider":"YOUPLUS","version":"1.0","type":"link"}
