PRESENTING THE HIGHLY ANTICIPATED HYBRID DRIVER IEM FROM FIIO - THE FH15

FiiO needs no introduction. It has evolved over the years and has developed & designed audio products that have amazed critics and audiophiles alike. FiiO's line-up of in-ear monitors (IEMs) has a wide range, and FiiO is known for including different cutting-edge technologies in their in-ear monitors. FiiO's FH series of in-ear monitors have always been revolutionary. This time, FiiO went back to the basics and took on the daunting challenge of bringing the sound quality of the FH series to new heights. Based on this philosophy, the FH15 was born. After four years of development and three generations of other product launches, countless experimentations & restarts emerged an IEM, the FH15. It is the result of innovation after a lengthy development process. The FiiO FH15 is a hybrid driver IEM that hosts 3BA and 1DD to give you the best possible reproduction of Hi-Res music ever imagined!

FEATURES A 10MM DYNAMIC DRIVER THAT PRODUCES EARTH-SHATTERING BASS RESPONSE

FiiO has included a newly developed 10mm Dynamic driver with a carbon-based diaphragm in the FH15. The FiiO development team used carbon-based materials for the Dynamic driver diaphragm to achieve exceptional transient performance and earth-shattering bass response. Because of its lightweight, high internal resistance, and excellent stiffness, carbon enables the Dynamic driver to react fast to changes in the input signal. The carbon-based diaphragm's thousands of stacked and woven cross-fibre filaments have a high internal damping, allowing the edge and centre to move swiftly together in the same direction while minimising driver breakage caused by disparate regions of the driver, moving out of sync. Less distortion & ultimately, cleaner sound are the effects of this. Through much objective data and subjective listening tests, FiiO developed a brand-new 10mm dynamic driver with a carbon-based diaphragm and combined it with other cutting-edge technologies in the FH15. The FiiO FH15 promises to give you a musical experience as if you are there right with the artists!

KNOWLES BALANCED ARMATURE DRIVERS PRODUCE MELODIOUS VOCALS AND DETAILED TREBLE RESOLUTION

The FiiO FH15 uses the unique Knowles ED BA drivers for mid frequencies. These drivers enable lusher vocals and a more musical sound, working in tandem with strategically positioned tuning holes in the FH15's shell. Two Knowles RAD BA drivers handle the treble, providing a remarkably airy sound with outstanding treble resolution and the ability to capture every last nuance of the song. These drivers allow you to experience music as if you were right there with the performers. The FH15's bass, mids, and treble are tuned to sound fantastic with all musical genres. Give your music a new definition and immerse yourself in pure sonic bliss!

CUSTOM-MADE NOTCH FILTER ELIMINATES ANY UNWANTED RESONANCE PEAKS

The most critical part of hybrid driver in-ear monitors is the transition and the tuning for the drivers to reproduce dedicated frequencies. For multi-driver hybrid earphones, combining them requires one to not only look at the drivers as a unit but also independently. FiiO first tuned each driver separately as if they were on their own and then scientifically combined the drivers. FiiO has incorporated a notch filter technology in the FH15 for this purpose. The notch filter is specifically custom-made for the FH15 and gives it its distinctive sound: A Helmholtz resonator works with the mid-frequency ED drivers, resulting in denser-sounding mids giving vocals and instruments more realism without sounding thin. Additionally, the resonator is connected to an opening to eliminate unwanted resonance peaks and overlapping frequencies produced by the different drivers. This design aspect helps maintain better coherency among the drivers while eliminating unwanted sibilance.

PATENTED S.TURBO ACOUSTIC DESIGN FOR HIGHLY COHERENT SOUND

FiiO has used its patented S.Turbo acoustic design to get the optimised frequency response for the FH15. The balance between bass, mids, treble and clarity is the ideal sound goal of many audiophiles, but this is easier said than done with multi-driver hybrid IEMs. This is because the multiple drivers naturally produce frequencies that overlap and interfere with each other. Thus, crossovers divide the frequencies between the drivers to achieve clear, coherent sound. The RC circuit design is used in the FH15 to manage the crossover in the higher frequencies by utilising a high-pass filter. The traditional low-pass filtering LC circuit controls the crossover of the lower frequencies. The FiiO development team worked with the basic principle of sound waves and developed the patented S.Turbo acoustic design. This design reduces frequency response overlap between the bass and mid drivers for more coherency between the different drivers and a more balanced frequency response for a cleaner and more natural sound.

TAILOR THE SOUND TO YOUR PREFERENCES WITH INTERCHANGEABLE SOUND FILTERS

FiiO is known for providing different sound filters allowing you to get the best possible sonic experience. This time with the FH15, FiiO has included three interchangeable sound filters with each pair, allowing for a different sound depending on the density of materials within the filter. The FiiO FH15 comes with Red, Black, and Green interchangeable filters. The Red enhances the bass response, the Black reproduces a balanced sound without emphasising any frequency, and the Green filter opens up the treble making it highly resolving. Tailor the sound to your sonic preferences with the all-new FiiO FH15!

FUTURISTIC DRAGON SCALE DESIGN WITH ALUMINIUM ALLOY CONSTRUCTION

The FiiO FH15 features an aluminium alloy construction with a dragon scale design allowing the IEM to give off a unique, exquisite feel. Due to the small area of the FH15's faceplate, precise five-axis CNC machining ensures that each texture on the faceplate is suitably 3D and eye-catching. Specifically, fine cutter heads of 0.8mm diameter are used in the CNC machining process to ensure that the textures on the faceplate are both suitably attractive to the eye and luxurious, feeling to the touch. The FH15 is a fresh reboot of in-ear monitor design, featuring a dragon scale motif in a moderately-sized oval shape that conforms and fits perfectly in the ear for greater comfort. The modern minimalistic lines transition smoothly into the classical dragon scale design elements, giving the FH15 a lively robust look.

BUNDLED WITH HIGH-PURITY LITZ-BRAIDED CABLE WITH SWAPPABLE TERMINATIONS AND HS18 EARTIPS

The FH15 comes with a 152-wire silver-plated monocrystalline copper cable featuring eight strands of Litz-braided wire. The Litz braiding specifically reduces the skin and proximity effects, leading to reduced eddy current losses and improved high-frequency resolution. Additionally, the audio plugs are swappable, and included are 3.5mm/4.4mm plugs. The FiiO FH15 comes loaded with accessories. One of the accessories is FiiO's HS18 eartips. Included with the FH15 are three pairs of the FiiO HS18 ear tips. Being only 0.4mm thick, the HS18 is comfortable to wear. The HS18 also features a large opening, the same size as the earphone nozzle, to minimise barriers between the earphone and eardrum for maximum detail and reduced high-frequency sound loss.
