Combining a large 97mm planar driver, precision magnetic control, natural materials, and an ergonomic design, the i5 is built for listeners who want an expansive and highly detailed presentation.\u003c\/p\u003e\n\u003cp\u003eAt the heart of the i5 is a 97mm planar magnetic diaphragm measuring just 2μm thick. Its magnetron-sputtered silver alloy coating is designed to provide fast, accurate diaphragm response and detailed sound reproduction, while 44 N50 neodymium magnets provide precise magnetic control. The result is a low-distortion presentation with fast transients and high levels of detail across the frequency range.\u003c\/p\u003e\n\u003cp\u003eThe open-back architecture allows sound to develop naturally around the listener, creating an expansive and holographic soundstage. An acoustically transparent grille helps reduce resonance while maintaining the open character of the design, making the i5 particularly suited to critical listening, high-resolution music, acoustic recordings, classical music, gaming, and other applications where spatial presentation matters.\u003c\/p\u003e\n\u003cp\u003eThe i5 is built around a handcrafted walnut acoustic chamber and CNC-machined aluminum frame, giving it a distinctive combination of natural materials and modern precision engineering. A genuine sheepskin headband and breathable protein-leather ear pads provide a comfortable fit, while the memory-steel headband, multi-axis earcup pivots, and silicone adjustment sliders allow the headphone to adapt to different head shapes and listening positions.\u003c\/p\u003e\n\u003cp\u003eWith a 28Ω nominal impedance and 98dB\/mW sensitivity, the i5 is relatively easy to drive compared with many high-end planar headphones, although Fosi Audio recommends an amplifier capable of at least 500mW for optimal performance.\u003c\/p\u003e\n\u003cp\u003eKey Features:\u003c\/p\u003e\n\u003cp\u003eOpen-back planar magnetic headphone design\u003cbr\u003eLarge 97mm planar magnetic driver\u003cbr\u003eUltra-thin 2μm diaphragm\u003cbr\u003eMagnetron-sputtered silver alloy diaphragm coating\u003cbr\u003e44 N50 neodymium magnets\u003cbr\u003e10Hz–50kHz frequency response\u003cbr\u003eLess than 1% THD at 100dBSPL\u003cbr\u003e98dB\/mW sensitivity at 1kHz\u003cbr\u003e28Ω nominal impedance\u003cbr\u003eRecommended amplifier power of 500mW or more\u003cbr\u003eHandcrafted walnut acoustic chambers\u003cbr\u003eCNC-machined aluminum frame\u003cbr\u003eGenuine sheepskin headband\u003cbr\u003eBreathable protein-leather ear pads\u003cbr\u003eMulti-axis pivoting earcups and adjustable silicone sliders\u003cbr\u003eAcoustically transparent open-back grille\u003c\/p\u003e\n\u003cp\u003eWhat's Included:\u003c\/p\u003e\n\u003cp\u003eFosi Audio i5 headphones\u003cbr\u003e4.4mm cable\u003cbr\u003eXLR adapter\u003cbr\u003eUser manual\u003c\/p\u003e","brand":"Stars Picker Audio Library","offers":[{"title":"Default Title","offer_id":46902381740229,"sku":null,"price":2419.0,"currency_code":"MYR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0577\/8748\/2309\/files\/ShopifyProductpages_33_5451e856-0c76-4c8b-ad1a-4bf2e5847f01.png?v=1789644458","url":"https:\/\/starspickeraudio.net\/products\/fosi-audio-i5-planar-magnetic-headphones-full-size-wired","provider":"Stars Picker Audio Library","version":"1.0","type":"link"}
