Fidue A66 Dynamic Driver Graphene Diaphragm HiFi In-Ear Earphone With Mic&Remote Control


Dual voice coil driving technology, more powerful driving force to bring better dynamic effect

The coaxial multi-voice coil drive technology, developed by FIDUE, makes use of two sets of voice coils on the common axis, which are independent from each other and have exactly the same conductive characteristics, and organically combines them together after precise production, makes the A66 sound unit is able to obtain greater driving force under the common drive of double voice coil while improving the sound control, so as to achieve better dynamic effect.

Graphene composite diaphragm, thinner, stronger, more abundant music detail performance

A66 uses a graphene laminating of less than 1 nm to make a dynamic diaphragm, which greatly reduces the adverse effects of diaphragm splitting vibration and greatly improves the resolution.

Graphene material is very light and thin, which can greatly improve the sound control of the earphone.
