Hybrid Dynamic-Balanced Armature design for double the detail

The FH1 adopts a hybrid design, in which the 10mm titanium diaphragm driver produces abyssal lows while the Knowles 33518 balanced armature driver provides exquisite mids and highs. These two drivers work perfectly in harmony to allow you to truly dive into a musical, yet highly detailed experience.

Highly-Acclaimed Knowles 33518 driver

The latest from the renown Knowles, the 33518 balanced armature, as used in the FH1 brings both a rich, yet delicate expression of music.

  • Brass for natural, effortless sound

    Theoretically, the closer the balanced armature unit is placed to the ear, the more accurate the sound is – because the ear will better receive the high of frequencies and overtones produced by the driver. However, if the tube through which sound travels through from the balanced armature to the ear is not designed properly, then even at short distances sound quality will degrade rapidly due to resonances and unwanted reflections. Therefore, to achieve the highest sound quality possible, we put the Knowles balanced armature unit inside the sound tube (to minimized its distance to the ear) made to brass (with its higher density than aluminum, it provides a more stable base with less undesirable resonances). All of this result in a natural, yet effortless sound in all parts of the sound frequency spectrum.

    Titanium dynamic driver for potent bass
    10 mm titanium diaphragm dynamic driver is responsible for the FH1’s powerful lower frequencies. Due to more space being available, the FH1’s diaphragm is 25.7% larger than the F9’s 9.2mm dynamic driver, making for not only more relaxed yet natural sounding vocals but also more robust bass – resulting in a highly dynamic, authoritative experience.

    Carefully-crafted crossover design for balanced, precise sound

    The FHI uses a meticulously designed crossover system so that the hybrid dynamic - balanced armature design can reproduce any frequency within the 20Hz to 40kHz range with the utmost fidelity. Essentially, the FH1’s drivers work perfectly in tune with each other that makes it ideal for a wide range of music.

    Hi-Res Audio Certification

    The FHI has been certified by the Japan Audio Society to be “Hi-Res Audio” capable. This means that the FHI is capable of a frequency response up to 40kHz, which can fully reproduce the audio and give you a natural and life-like listening experience that truly lets you listen to the music the way the artist wanted it to sound.

  • Red, green, blue and black, for a more colorful you

    To be more in touch with your unique personality, the FH1 is offered in four different colors: Gunmetal Grey, Sky bule, Chinese Red, and Emerald Green. Note: Images shown is illustrative purpose only. Actual product color may vary.

    Unexpectedly Thoughtful Accessories

    Besides the 2.5mm balanced and 3.5mm single-ended cables, the FH1 comes with a whole host of other accessories all designed to tailor and safeguard your listening experience. For instance, the FHI comes with two different kinds of ear tips — one set optimized for bass while the other is designed for a more balanced presentation. Each type of ear tips comes in small, medium, and large sizes. We give you control over your listening experience, so you can listen however you want, whenever you want. The FHI also comes with our popular waterproof carrying case, so you can be rest assured that your earphones will continue to function for years to come.
