FIIO FD11

FiiO FD11

The FiiO FD11 is a brand new entry-level IEM with a single dynamic driver that reproduces an excellent and clear soundstage. The pair includes a 10mm dual-chambered dynamic driver that uses a high-quality carbon-based diaphragm to produce impressive sound with a balanced three-frequency response. You get a powerful low, clear midrange and smooth, detailed treble. Experience rich timbre and beautiful sound with the all-new FiiO FD11.

High-quality sound with high-quality dynamic driver

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

Asymmetric external and internal magnetic fields

FiiO has equipped the FD11 with second-generation asymmetric internal and external magnetic circuits. The pair was developed using finite element simulations that optimize the magnetic circuit design to produce a strong and powerful magnetic field. The result is a higher magnetic field density that enables switching movements of the aperture and promises high-quality sound reproduction.

Excellent design, comfortable fit

The FiiO FD11 is designed with the brand's ultimate craftsmanship. The pair features high-quality zinc alloy shells that are decanted into the mold and then polished and electroplated to treat users to an outstanding end product. It has a shell-like shape. The pair has an ergonomic shape that promises a comfortable feel for users.

C-shaped acoustic flute design

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

Refined frequency response curve

FiiO is one of the most experienced brands in the hi-fi audio industry. They have refined the FD11's tuning to deliver a clean and detailed sound. The pair has strong midrange clarity for 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 significantly improves the performance of the pair by providing smooth signal transmission and low internal resistance.
