High quality sound with high quality dynamic driver

FiiO has crafted the FD11's 10mm dynamic driver from the same materials used for the FH15 and FF5 IEMs. The FD11 gets a significant boost in its sonic capabilities from this high-quality dynamic driver. It features a dual-cavity design and a carbon-based diaphragm material. This gives the pair a very responsive sound with smooth timbre and minimal distortion.

C-shaped design of the acoustic flute

FiiO has integrated its C-shaped acoustic flute into the ear cup of the FD11. This significantly improves the sound performance, especially in the lower frequency range. As the air moves through the FD11 cups, the C-shaped acoustic flute helps to increase the viscosity of the air and reduce resonance in the output signal. This helps to improve the quality of the mid and lower bass!

Finely tuned frequency response curve

FiiO is one of the most experienced brands in the Hi-Fi audio industry. They have fine-tuned the tuning of the FD11 to deliver clean and detailed sound. The pair boasts strong midrange clarity that provides realistic vocal reproduction.

High quality standard cable

The FiiO FD11 comes with a high quality standard cable. It is a high purity 4-core oxygen-free copper cable with 120 cores in each strand. The high quality oxygen-free copper material greatly improves the performance of the pair as it provides smooth signal transmission and low internal resistance.
