2.What is the tuning style of the FH3? What type of music is it friendly?

The 10mm beryllium-plated diaphragm dynamic driver in the FH3 was specifically chosen for its superior acoustic properties. The beryllium-plated diaphragm is not only light and thin but is also extremely rigid, allowing for thunderous yet lightning-quick, responsive, and dynamic bass. Mid-frequencies using the ED-30262 gives sweeter and fuller vocals as well as a wider soundstage. High-frequencies using the Knowles RAD-33518 driver provides extremely clear sound with well-extended yet smooth treble.-- Suitable for various instrumental and pop HiFi music.
