• Config: Carbon-based diaphragm DD(lighter but harder)+ Knowles ED+RAD BAs;
• Tunning: Approaching-to-Harman curve(in-ear) lower midrange tunning;
• Adaptability: Treble tunning range: *dB (through the filters provided);
• Tech: 5~6khz is smoothed by the Notch filter, so that illusive resolution and harshness are avoided;
• Accessories: silver-plated monocrystalline cable with interchangeable plugs.

10mm carbon-based diaphragm dynamic driver

Carbon’s light weight, strong rigidity and high internal resistance means that the dynamic driver can quickly start and stop movements when responding to changes in the input signal.

10mm——Large dynamic driver
9 times——Tensile strength 9 times that of steel
1/4——At the same volume, ¼ lighter than Beryllium

Custom Knowles BA drivers

For mid frequencies, the FH15 employs the custom Knowles ED-30262 BA drivers which allows for lusher vocals and a more musical sound.

Treble is handled by 2 Knowles RAD-33518 BA drivers, which are capable of high treble resolution and capture every last detail in the music, for a truly airy sound.

Custom notch filter

When looking at the frequency response curve, it can be seen that the response between 1 kHz and 4kHz has been improved, resulting in denser-sounding mids giving vocals and instruments more realism without sounding thin.

S.Turbo patented design

To hit our mid and treble sound goals for the FH15, we filter the higher frequencies produced by the bass driver in a low-pass filter, the S.Turbo acoustic design. This design reduces frequency response overlap between the bass and mid drivers for more coherency between the different drivers and a more balanced frequency response, for a cleaner and more natural sound.

Interchangeable sound filters

Red filter—— enhanced bass, for a bold sound

Black filter—— balanced sound, transparent and clear

Green filter—— exquisite treble, highly resolving

Excellent frequency response
