FiiO FH15 Quad-Driver Hybrid In-Ear Monitors (Black)

FiiO FH15 Overview

Enjoy high-resolution music with the FiiO FH15, a pair of customizable in-ear monitor headphones that are designed to reproduce any style of music with power and clarity. The FH15 features two high-frequency balanced armature drivers, a custom midrange BA driver, and a single 10mm carbon-based dynamic driver, which combine for a full frequency sound (10 Hz to 40 kHz).

The sound signature of the FH15 can be customized thanks to the three audio filters (Bass, Balance, Treble). Additionally, the headphones include 16 pairs of eartips, which further enhance the overall performance including Bass, Balance, Vocals, and the new HS18 for reduced high-frequency loss and improved resolution. The FH15 also includes a carrying case, cleaning brush, and other accessories.

FH15 Design

• Low frequencies are produced by the new 10mm dynamic driver with a carbon-based diaphragm
• Mid frequencies are produced by a custom Knowles ED BA driver
• High frequencies are produced by a pair of Knowles RAD drivers
• Bass, mids, and treble have been tuned in a way that allows the FH15 to sound great with all genres of music.
• Should you wish to customize your listening experience to focus on a particular instrument, such as piano, guitar, violin, etc., the FH15 features interchangeable filters with distinctly different sounds.

10mm Dynamic Driver with Carbon-Based Diaphragm

FiiO chose carbon for its lightweight, strong rigidity, and high internal resistance. The driver can quickly start and stop movements when responding to changes in the input signal. The high internal damping allows the driver`s edge and middle to move in synchronicity, minimizing breakup of the driver and reducing distortion.

Custom Knowles BA Drivers

• The mid frequencies are produced by a custom Knowles ED BA driver that works in conjunction with specially placed tuning holes in the shell of the FH15, allowing for lusher vocals and a more musical sound.
• Treble is produced by a pair of Knowles RAD BA drivers, which are capable of the high resolution and reproduce every last detail in the music for a truly airy sound.

Patented S.Turbo Design for Optimized Frequency Response

For a cleaner and more natural sound, the S.Turbo acoustic design filters the higher frequencies produced by the bass driver with a low-pass filter. This design reduces frequency response overlap between the bass and mid drivers delivering a more coherent sound and a more balanced frequency response.

Interchangeable Sound Filters and Eartips

Audio Filters

• Red filter: enhanced bass for a bold sound
• Black filter: balanced sound, transparent and clear
• Green filter: Exquisite treble, high resolution

Eartips

• Red and black eartips: bass eartips, which can improve the bass sense.
• Translucent black eartips: balanced eartips, actual listening experience may vary from users.
• Red and white eartips: vocals eartips, more outstanding on mids performance with front vocals.
• Translucent white eartips: design for the small sound tube, which can be inserted deeper into the ear canal for richer sounds.
• Memory foam eartips: more fitting for ear canals with better sound insulation and noise cancellation effects.
• HS18 eartips: provide comfortable wearing experience and reduce high-frequency loss and improve resolution.

Litz-Braided Monocrystalline Copper Cable

The FH15 includes a 152-wire silver-plated monocrystalline copper cable featuring eight strands of Litz-braided wire. The Litz braiding reduces the skin and proximity effects, leading to reduced eddy current losses and an improved high-frequency resolution. Additionally, the audio plugs are swappable and include 3.5 and 4.4mm plugs.
