FiiO FH7 Hybrid In-Ear Monitors The FiiO design team went through many design iterations and tests to create an extremely comfortable design that seals great in your ear. Through optimizing the damping and internal structure, the air pressures at the front and rear cavities of the FH7 are balanced, relieving uneven pressure from your eardrums for greater comfort when listening. The FH7’s shell is made of aerospace-grade aluminium-magnesium alloy, shaped by five-axis CNC machining. Stunning on the outside, but also powerful on the inside - 4 Knowles DFK+SWFK BA driver units The FH7’s 4 Knowles balanced armature drivers plus a beryllium dynamic driver perfectly cover all parts of the sound frequency spectrum through sophisticated crossover and turbo acoustics design High and ultra-high frequencies: These parts of the frequency spectrum are handled by the Knowles DFK+SWFK BA driver, often utilized in top-of-the-line IEMs. This driver is extremely detailed but without being harsh, giving you natural, crystal-clear sound. Mid frequencies: This is handled by a custom BA driver designed by FiiO and Knowles in conjunction with each other. FiiO took the classic Knowles 30017 driver and tweaked it to give the mids more body, for fuller and sweeter vocals as well as a larger soundstage. Low frequencies: The 13.6mm large dynamic driver is made of beryllium, known for being light, thin, yet extremely rigid for even deeper, explosive bass. The brilliance of 13.6mm Beryllium diaphragm dynamic driver The FH7 dynamic driver’s diaphragm contains beryllium, famous for its’ unparalleled lightness, flexibility, and rigidity that allows for spectacular bass. Get a rush with S.TURBO acoustic design On the FH7 is the next generation of FiiO’s patented acoustic design – S.TURBO V2.0, further optimised to extract even more performance out of the dynamic driver. The longer and more acoustically optimised sound pipes, inspired by turbines, give deeper and more robust bass that will truly feel knocked into you. Create your own sound – 3 pairs of interchangeable sound filters Give your ears a jolt with the right sound. FiiO have realized that everybody has their own ideal sound, so they give you 3 pairs of carefully designed sound filters to get the FH7 sounding exactly the way you want it. RED - Dynamic bass emphasis BLACK - Balanced GREEN - Detailed treble emphasis Getting serious with 8 strands of high-purity silver wires The FH7 cable is composed of high-purity Litz monocrystalline copper-plated silver wires – 152 of them in fact, bundled into 8 strands. FiiO are serious about getting you the best possible sound with the FH7. In the Box
