A translucent shell that piques your curiosity\nTha translucent industrial-grade polycarbonate housing attracts with its look into the F1's internals.\n\nA lightweight IEM designed for fatigue-free listening\nThe use of an ultra-lightweight polyester diaphragm in its specifically-tuned dynamic driver gives the F1 a natural and relaxed toanlity that works well with modern pop music.\nSince each in-ear unit weighs only 2.4 grams, the F1 (unlike many other IEMs) when worn simply disappears from your ears, allowing you to fully enjoy your music.\n\nJapanese copper-clad aluminum voice coil\nA lighter voice coil makes for faster transients and better overall sound quality. This exactly describes the Japanese copper-clad aluminum voice coil utilized in the F1, which allows it to present a transformative listening experience by clearly bringing forth even the subtlest of details within the music.\n\nErgonomic and comfortable to wear\nThe comfort and fit of an in-ear monitor is arguably just as important as its sound quality. With this knowledge, FiiO very seriously took on the challenge of making a comfortable IEM. After studying many people's ear canals, it was found that a 45-degree angled design allows the in-ear unit to better and more comfortably fit the human ear canal, thus, the F1 adopts this design, which allows to create a better seal with the ear, blocking external noise more effectively and allows your music to more vividly come through.\n\nDifferent ear tips for different sounds\nThe F1 includes 3 different sizes of ear tips. Not only does this allows the user to choose a size based on what is comfortable for them, but also allows them to choose the sound they want since different ear tips have different sound signatures. The ear tips are made of medical-grade silicone, which are both comfortable to wear and environmentally-friendly to boot.\n\nConvenient aluminium alloy in-line controls\nA single cable to control your music and your calls without missing a beat. The F1's in-line control unit is made os aluminium alloy, which prevents it from oxidizing and makes for a better feel. The F1's in-line controls are fully compatible with FiiO's newer X-series players, such as the X1 II.\nThe high-definition microphone and call button are also compatible with iOS and Android devices. Volume adjustment is also available for Android devices.\n\nSophisticated attention to detail\nFrom the 3.5mm L-type gold-plated plug, to the cable cinch, to the CD pattern finish, to the clear left/right channel identification marks, every detail on the F1 is carefully thought out so each part can live up to the excellent sound quality.\n\nRobust, yet lightweight polyurethane cable\nAfter extensively experimenting with and evaluating a wide variety of materials on a multitude of factors, polyurethane emerged as the material of choice for the F1's cable. Polyurethane is a low microphonic, durable material that is also lightweight, highly elastic and tough against scrapes.\n\nReliable 90º plug\nThe F1 adopts a 90º L-type headphones plug in order to effectively prevent accidental bending of the plug when knocked against, making it more resistant to the bustle of everyday life. The gold-plated plug not only ensures that it will not oxidize, but also minimizes audio signal loss.\n\nStrict quality testing for reassurance\nFiiO subjects its products to quality standards stricter than what is normally found industry-wide, all to give you the highest-grade goods.
