FiiO FD11 Single Dynamic In-Ear Monitors w. Detachable Cable

Pure rhythm, dive into your music
The FiiO development team created the FD11 as a part of a new “Bionic Conch” series of products that aims to punch above its price class in both aesthetics and sound. High-end techniques were used to create the unique sense of flow that the FD11 radiate from their appearance, and innovative features such as the C-shaped acoustic flute elevate the sound quality to the next level by giving a truly “cohesive unified” sound.

Higher-end materials for a higher-end sound, 10mm carbon-based dynamic driver
For the FD11’s 10mm carbon-based dynamic driver, the development team chose to use the same materials as found in the high-end FH15 and FF5 IEMs, giving the FD11 a serious boost to its sound capabilities. The carbon-based material is ideal for the diaphragm – being lighter than aluminum, beryllium, and other materials while having a tensile strength nine times that of steel. 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.

Experience robust, quick bass! Dual cavity dynamic driver
The rear of the FD11’s dynamic driver features a unique dual-layer cavity, allowing the development team to install damping control systems in both the inner and outer chambers to precisely control air flow – resulting in reducing distortion and allowing the diaphragm to move more freely without breakup. This results in both more detailed treble and especially more robust and more resolving bass, with the driver faithfully reproducing low-frequency details with astonishing speed.

Classy craftsmanship on display, liquid die-cast zinc alloy construction
Affordable price, high-end craftsmanship – this is what you get with the FD11. FiiO took the “conch” as its inspiration for the FD11 design. Zinc alloy is the material of choice for constructing the FD11 in order to give it a unique flowing appearance. This zinc alloy is die-cast into its shape, and then polished and electroplated to give it a high-end look and feel rarely seen in its class.

Tailor-made for pure brilliance, fine tuned frequency response
The development team has placed special care in making sure the dynamic driver produces a smooth, easy-to-listen sound thanks to continuous, science-driven efforts. Even though the FD11 features a single dynamic driver, that dynamic driver’s light carbon-based diaphragm not only allows it to handle bass frequencies with aplomb, the driver also is capable of producing sound with specially optimized emphases at certain points like 14kHz and 18kHz that allow it to clearly reproduce the details in your music. Compared to the FD11, there is less emphasis on the bass frequencies but more emphasis on realistic sounding vocals – for a more forward sound with a more apparent sense of space.

Triangular ergonomic design
We may start from the appearance, but we end up focusing on the tiny details. With the FD11, we continue our earnest efforts in innovating in both its appearance and how it feels to wear. The “conch-like” shape of the FD11 is specifically designed to optimize the contact area between the earphone and the human ear, forming a triangular support structure so that it remains securely in your ear no matter the situation.

0.78mm dual pin detachable cable
The FD11 uses a 0.78mm dual-pin cable, allowing you to easily upgrade your listening experience later. The elbow-shaped headphone connector is also specially curved to make it both easier to use and more comfortable to wear.
