It has FiiO's latest acoustic patent F.T.B.S \"Tesla Valve\" low-frequency loading technology. Coupled with its premium manufacturing quality and exquisite craftsmanship, FD15 sets a new standard for sound reproduction. FD15 is the ideal choice for audiophiles who pursue unparalleled audio performance. It promises to provide an immersive listening experience that exceeds expectations.\n\nThe FD15 introduces a truly high-end headphone-grade metal diaphragm—magnesium-aluminum alloy dome with DLC suspension. This innovative combination of materials enhances the listening experience profoundly: not only does the FD15 faithfully reproduce the spacious and soft essence of \"circle taste,\" but it also achieves significant advancements in high-frequency extension and resolution. As a result, the overall sound is characterized by its bright transparency and refined delicacy.\n\nThe FD15 is equipped with the F.T.B.S \"Tesla Valve\" low-frequency loading acoustic patent technology. Leveraging advanced powder metallurgy, the FD15 achieves precise calculations of branch length, angle, and quantity in the earcup cavity. This engineering results in a fluidic structure that matches the acoustic design of the Tesla Valve, significantly enhancing the headphone's capability to reproduce deep, resonant low frequencies. Experience a profound and immersive bass response that truly captivates.\n\nThe all-new FD15 comes standard with a cable crafted from Furukawa single crystal copper and Furukawa single crystal copper plated with silver.The cable's raw materials are sourced from authentic Furukawa imports from Japan, featuring a cross-sectional area as large as 22AWG, it rivals the quality of high-end HiFi headphone cables typically found in thousand-dollar ranges, making luxury affordable and accessible.\n\nThe FD15 boldly adopts Hi-End level audio design principles by incorporating a W-shaped independent suspension design in its headphones. Compared to conventional diaphragm designs of the same size, this innovation increases the effective vibrating area by 30%. The larger effective diaphragm area and greater amplitude enable the acoustic core unit to store more sound energy, delivering a more dense and grounded auditory experience for listeners.","brand":"FiiO","offers":[{"title":"Black","offer_id":49051559362727,"sku":"TekFX-FD15Black","price":164.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0699\/8546\/8583\/files\/medium_f9caa3a5-bb3b-416d-b2c1-04d825607f2c.jpg?v=1777335544","url":"https:\/\/www.zentrallc.com\/products\/fiio-fd15-13-8mm-magnalium-dlc-hifi-dynamic-driver-in-ear-earphone-with-stainless-steel-shell-detachable-mmcx-cable-black","provider":"Zentra, LLC","version":"1.0","type":"link"}
