Sound signature: the FD11, which has deep lows, smooth mids and treble, would be a nice choice for vocal-heavy, folk music lovers. It has a mild V-shaped sound with bass boost;

The FD11 has adopted carbon-based dynamic drivers, which have the characteristics of higher hardness, light weight and lower distortion.

Response speed has been improved by the "double-magnet" design (coil inner magnet + outer magnet) and stronger magnets also make it easier to drive;

Liquid metal die-cast housing, which effectively inhibits resonance to enhance clean sound. The extended acoustic-damping-flute design improves the bass extension. Mirror-finished surface, tempered-glass faceplates and 0.78mm connectors.

10mm carbon-based diaphragm
The carbon-based diaphragm results in a highly-responsive and detailed driver that can easily handle quick transients with minimal distortion thanks to minimal breakup during driver movement.
Fine-tuned frequency response
FD11: Focus on dynamic driver timbre, with special attention on vocals, suitable for vocal-heavy, folk, ACG and other styles of music
symmetrical internal and external magnetic circuits
What the strong magnets get you for trebles and for its sound in general is a quicker transient response that bodes extremely well for IEMs. Trebles here benefit from the materials.
Dual cavity dynamic driver
Speedy, punchy, tight and well defined. The bass end will please folks that like to have some thump with their harmon tunings.
C-shaped acoustic flute
This design is used to regulate the airflow in the rear cavity and optimize the performance of mid-to-low frequencies.
Liquid die-cast zinc alloy construction
Thanks to the die-cast shape, the internal surface of the FD11 is slightly uneven, just enough to significantly reduce sound wave convergence, and minimize standing wave generation – all resulting in purer sound.
