The F3 in-ear monitor earphones utilize a cutting-edge graphene driver diaphragm, a groundbreaking new material with unprecedented thinness and flexibility. With a thickness of only 0.335nm, the graphene diaphragm is extremely strong and with excellent conductivity. Due to its properties, a graphene driver can very faithfully reproduce music with a clean, rich, yet transparent high-fidelity sound.
Special Voice Coil
A lighter voice coil makes for faster transients and better overall sound quality. This exactly describes the copper-clad aluminum voice coil used in the F1, which allow sit to present a transformative listening experience by clearly bringing forth even the most subtle of details within the music.
Robust and Reliable Cable
Through extensive tests and evaluation of a wide variety of materials on a multitude of factors, polyurethane emerged as the material of choice for the F3's cable. Polyurethane has low microphonic, and is both durable and light weight. Its highly elastic and tough characteristics protect against scrapes and wear. Smartphone Support
The F3 Gen incorporates a crystal clear microphone and call/volume control buttons. These controls not only works perfectly with the X1-II and X5-III music players, but also supports most Android smartphones. The microphone and call button works with iOS devices, but volume control does not.
From the 3.5mm L-type gold plated plug, to the cable cinch, to the textured finish, every detail on the F3 is carefully thought out so each part lives up to the excellent sound quality. Three interchangeable shells lets you choose the color you want: black, red, or blue. Over-the-ear cable routing is comfortable, secure, and helps further isolate microphonic noise.
