{"product_id":"fiio-fx15-six-driver-hybrid-in-ear-monitors","title":"FiiO FX15 Six-Driver Hybrid In Ear Monitors","description":"\u003cp\u003eThe FiiO FX15 is a tribrid in-ear monitor and FiiO’s first with electrostatic drivers. Each earpiece combines four Sonion electrostatic tweeters for the highest frequencies, a Knowles balanced armature for the mids and treble, and a 10mm DLC dynamic driver with FiiO’s patented S.Turbo bass tube, and a switch on each earpiece turns the electrostatics on or off so you can hear exactly what they add. The shells are precision 3D-printed by HeyGears, and a 224-wire silver cable with twist-lock 3.5mm and 4.4mm plugs is included. It is Hi-Res Audio certified and won a CIHE EHA 2023 Silver Award and a VGP 2024 Summer award.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-fx15-six-driver-hybrid-in-ear-monitors-photo-hero.jpg?v=1791323162\" alt=\"FiiO FX15 tribrid in-ear monitors\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eSlow is fast\u003c\/h3\u003e\n\u003cp\u003eElectrostatic IEMs are no longer a novelty at the high end, but the FX15 is FiiO’s first. Electrostatic drivers are not very sensitive, so they are easily drowned out by the dynamic and balanced armature drivers around them, and FiiO’s team spent a long time on getting them to work in harmony before releasing it. As FiiO puts it, being slow makes you end up faster.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-fx15-six-driver-hybrid-in-ear-monitors-photo-exploded.jpg?v=1791323165\" alt=\"Exploded view of the FiiO FX15 drivers and shell\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eFour Sonion electrostatic drivers\u003c\/h3\u003e\n\u003cp\u003eElectrostatic drivers are known for high-frequency detail but are usually found only in very expensive IEMs. The FX15 has four per side, giving exceptional ultra-high-frequency extension and the speed to reproduce every last detail: a real taste of high-end audio.

FiiO reduced its sensitivity through the shell design and other measures, so the balanced armature and the electrostatics each cover their own range without getting in each other’s way, for a smooth overall response.\u003c\/p\u003e\n\u003ch3\u003eA 10mm DLC dynamic driver\u003c\/h3\u003e\n\u003cp\u003eThe 10mm DLC (diamond-like carbon) driver was chosen for its high rigidity and damping, for a robust, full sound that is detailed yet easy to listen to.
