Making big waves from tiny ripples

New 4 BA Dynamic Driver Flagship IEMs - FH7

Custom Knowles BA Driver | 13.6mm beryllium dynamic driver | Patented S. Turbo acoustics design | Exotic-inspired acoustics design | 8-stranded monocrystalline silver-plated copper cable

Exquisite traditional craftsmanship - An indication of its compelling sound

The shell of the FH7's recalls nature - specifically, the ferocity dominance of great water waves, an indication of the powerfully mesmerizing sound you will be simply swept away by. 

Aerospace-grade aluminium-magnesium alloy, treated with five-axis CNC machining

The FH7's shell is made of aerospace-grade aluminium-magnesium alloy, shaped by five-axis CNC machining. To ultimately create the shell, the alloy needs to go though 21 steps in a total of 3873 cuts, and is finished with a final round if sandblasting and hand polishing. 

Specially-customized design that just fits

The FiiO design team went through many design iterations and test to create an extremely comfortable design that seals great in your ear. You will find that the FH7 is easy.

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 drivers perfectly cover all parts of the sound frequency spectrum though sophisticated crossover and turbo acoustics designs. 

High and ultra-high frequencies: These parts of the frequency spectrum are handled by the Knowles SWFK-31736 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. We 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 contains beryllium, famous fot 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 optimized to extract even more performance out of the dynamic driver. The longer and more acoustically-optimized sound pipes, inspired by turbines, give deeper and more robust bass that will truly feel knocked into you!

Getting the pressure off of your eardrums

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. 

Exotic-inspired independent sound tubes - Take a trip though the majestic frequency response

The FH7 utilizes a complex crossover design that was not easy to create and implement. However, it pays off by allowing extremely accurate crossover tuning that enables the five drivers to work together to their maximum potential, with an extremely coherent and smooth frequency response. 

Exotic-inspired acoustic structural design

Powerful drivers need to be contained in a solid shell for maximum performance. The FH7 employs an exceptionally rigid three-point structure to greatly reduce unwanted resonance and distortion, for the purest sound possible.

Culmination of the pursuit of great sound

The FiiO acoustic design team, despite with its over 30 years of experience and know-how, has continued to relentlessly pursue great sound. The FH7 once again raises the bar for what FiiO can do - high-end drivers in a cleverly engineered acoustical design that makes for a sound well-suited for all kinds of music. 

Create your own sound - 3 pairs of interchangeable sound filters

Give your ears a jolt with the right sound. We realize that everybody has their own ideal sound, so we give you 3 pairs of carefully-designed sound filters to get the FH7 sounding exactly the way you want it. 

Select a filter based on the sound you want:

• Red - Dynamic bass emphasis
• Black - Balanced
• Green - Detailed treble emphasis

Impeccably ergonomic in every way Color-coded MMCX connectors

The MMCX connectors are slightly expanded as well as color-coded - blue left, red right - to help you easily change cables. This is just one of the many details of the FH7 specifically designed to make it comfortable to use. 

Getting serious with 8 strands of high-purity silver wires

The FH7 cable is composed of high-purity Litz monocrystalline copper-plated silver wires - 152b of them in fact, bundled into 8 strands. We're serious about getting you the best possible sound with the FH7. 

Professional from start to end Hi-Res Audio certified

The FH7 has been certified to be "Hi-Res Audio" capable, capable of reproducing music exactly the way the artist wanted.
