The FiiO F7 Hybrid In-Ear Monitors are the flagship model in the company's series of in-ear headphones. They offer a sleek look as well as a hybrid driver design, one that combines a 13.6mm beryllium dynamic driver with four Knowles balanced armature drivers. This results in a sound suitable for DSD or high-res PCM playback.

The dynamic driver handles the low-end, while the mids and highs are supported by the balanced armatures. With the F7, you can expect a full soundstage, a tangible absence of harshness, and an extended bass response.

Great care was taken with the construction of the drivers and their surrounding shell. For instance, the dynamic driver has been outfitted with long, acoustically optimized sound pipes, arranged in a design FiiO has deemed S.TURBO V2.0. This construction ensures the best performance possible from the particular arrangement of these drivers. The shell, on the other hand, utilizes an aerospace-grade, machined aluminum-magnesium alloy to house the drivers.

Comfort has also been considered—physical and sonic alike. These in-ear monitors were designed to sit easily in the ear. They also come with three pairs of interchangeable sound filters, one for dynamic bass emphasis, another for dynamic treble emphasis, and a third for a balanced sound.

The FH7's cable employs Litz monocrystalline copper-plated silver wires braided into eight strands, ensuring a high-quality sound from the MMCX connections that link to each earbud and to the 3.5mm plug that connects to your portable media player or home-listening station. Also included are three pairs of SpinFit ear tips.
