{"type":"firestarter.listing","listing":{"id":"lst_fstG305f","product_name":"FiiO FT5 90mm Open Back Planar Magnetic Headphones","category":"Headphone","description":"A sonic revolution in headphone technology\nWelcome to the FiiO FT5 90mm Open Back Planar Magnetic Headphones, a breakthrough in personal audio that combines cutting-edge technology with unparalleled comfort. FiiO's first set of planar magnetic headphones, they feature large 90mm drivers, a feather-like 6um ultra-thin diaphragm, and high-end micron-plated aluminum-silver alloy coils. \nRide the lightning: Planar magnetic drivers\nPlanar magnetic technology brings together the best of dynamic and electrostatic headphones, offering rich detail and incredible power. The FT5 leverages a large 90mm planar magnetic driver, utilizing 20 neodymium magnets per driver to give your audio a life-like quality rarely found in headphones.\nWhisper-thin yet durable: 6um ultra-thin diaphragm\nBalancing sound quality and reliability can be a tricky feat. But FiiO nailed it with a 6um ultra-thin diaphragm that is both resilient and capable of producing high fidelity sound. Tested extensively to find the ideal thickness and material, this diaphragm proves that bigger isn't always better.\nMicron-plated aluminum-silver alloy coils\nThe FT5's design emphasizes meticulous attention to detail, particularly in its coil construction. FiiO’s selection process for materials involved comprehensive testing, leading to the choice of a lightweight aluminum alloy intermingled with silver. This composition was chosen for its ability to improve conductivity. Such precise material engineering aims to deliver an auditory experience that not only satisfies but surpasses the standards of audio enthusiasts.\nMagnet harmony: 20 neodymium magnets per driver\nBy carefully balancing 11 magnets inside and 9 outside the driver, the FT5 achieves a harmonious magnetic field. This optimized setup leads to a consistent driver movement and significantly reduced distortion, offering you a higher fidelity sound experience.\nPower without the bulk: High sensitivity and easy to drive\nGone are the days of lugging around bulky
