Japanese Copper-clad Aluminum Voice Coil
This exactly describes the Japanese copper-clad aluminum voice coil utilized in the F3, which allows it to present a transformative listening experience by clearly bringing forth even the subtlest of details within the music.
A lighter voice coil makes for faster transients and better overall sound quality.
Try different ear tips for different sounds.
The F3 includes 3 different sizes of ear tips. Not only does this allow 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.

The F3's in-line control unit is made of aluminum alloy, which is not only lightweight yet durable but also is resistant against oxidation, making for a better feel. The F3's in-line controls are fully compatible with FiiO's newer X-series players, such as the X1 2nd gen. The high-definition microphone and call button are also compatible with iOS and Android devices. Volume adjustment is also available for Android devices*.
Convenient Aluminum Alloy In-Line Controls
A single cable to control your music and your calls without missing a beat.
After extensively experimenting with and evaluating a wide variety of materials on a multitude of factors, polyurethane emerged as the material of choice for the F3's cable. Polyurethane is a low microphonic, durable material that is also lightweight, highly elastic and tough against scrapes.
Polyurethane - robust, yet lightweight
Attractive, not Gaudy
The translucent industrial-grade polycarbonate housing attracts by allowing you to peer into and appreciate the F3's internals. The lustrous, vacuum-ion electroplated shell of the F3 is also exchangeable, allowing you to spice up your life by letting you change between different shells to fit your current mood.
Graphene Driver Diaphragm
The F3 utilizes a cutting-edge graphene driver diaphragm. Graphene, with a thickness of only 0.335nm, is a new nanomaterial that is extremely strong and has excellent conductivity. Due to its properties, a graphene driver diaphragm can very faithfully reproduce your music - giving a clean, rich, yet transparent high-fidelity sound.
Groundbreaking new material with unprecedented thinness and flexibility.
