4. What is the tuning style of the FD3/FD3 Pro？
The FD3 is an entry-level HiFi earphone model following the footsteps of the FD5. As a complementary product, the FD3 inherits the merits from the FD5 by using a large 12mm dynamic driver with its diaphragm using Diamond-Like Carbon (DLC) with a robust magnet of 1.5 Tesla magnetic flux. It becomes more lively in sound tuning and more capable in pop music yet with excellent resolution in high frequencies. Compared with the FD3, the FD3 Pro comes with warmer vocals and higher resolution capacity in high frequencies when equipped with a pro-grade cable.
