FiiO FD11 is the first earplug in the newly developed "Bionic Conch" series (in Norwegian: Bionic Konkylie). With this series, FiiO pushes the boundaries of what is possible to achieve in terms of sound and appearance in the budget class. High-tech techniques are used to create a unique flow in the sound, which is also reflected in the appearance. With unique features such as "C-shaped acoustic flute", FiiO lifts the sound to a new level for a truly seamless and unified sound image.
