FiiO FH7s - KopfhoererHeadsets - 148116

With the FH7s, FiiO has captured the essence of the big brother FH9 and tailored it to a 1+4 hybrid design. You get a 2nd gen self-developed 13.6 mm DLC dynamic driver, two DFK drivers for the midrange (specially made by FiiO and Knowles) and two SWFK-31736 drivers for the treble. The 13.6 mm dynamic driver is the same as in the FH9 and reproduces the powerful and deep bass we are familiar with. The membrane is made of DLC (Diamond-like Carbon) which contributes to an insane transient response due to properties such as high stiffness, lightness and strong damping in the material.
