Buy FiiO FH1 balanced armature-dynamic hybrid in-ear monitors with mic at very low price from this official storeHybrid 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 providing 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 soundTheoretically, 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 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 minimize its distance to the ear) made of brass (with its higher density than aluminum, it provides a more stable base with less undesirable resonances). All of this results in a natural, yet effortless sound in all parts of the sound frequency spectrum.Titanium dynamic driver for potent bassA 10mm 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 musical experience.Carefully-crafted crossover design for balanced, precise soundThe FH1 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.Freely switch between balanced and single-ended with standard MMCX connectorsThe FH1 utilizes the standard MMCX connector for its interchangeable cables, and comes standard with both 2.5mm balanced and 3.5mmm single-ended cables.The 2.5mm balanced cable is made of silver-plated copper wire, which ensures a balanced sound signature and a high level of detail retrieval. Of course, due to its balanced nature, the left and right channel wires are separated so that there is significantly greater channel separation - leading to a richer, more detailed musical experience.The 3.5mm single-ended cable comes with a full set of in-line controls capable of playing/pausing songs, switching tracks, volume adjustment, and even calls with its high-quality microphone. This makes the FH1 a perfect complement to enhance your experience with your portable audio player or cell phone.Colors and texture for easy identification and replacementThe end of the MMCX cable’s left channel is adorned with a splash of blue, while the end of the right channel is trimmed with a touch of red – for easy identification of the audio channels in a subtly stylish way. These channel ends also have a spiral texture engraved into them, for just the right amount of friction to greatly aid in removing and replacing the cable.Un Bel Oeil – A Beautiful EyeThe FH1's name is derived from the French way to say “a beautiful eye” - so chosen to reflect the FH1's oval, pupil-like design. This design is further enhanced with the presence of the chrome trim, specifically placed to recall one's eyelids. The FH1 will surely catch your eye with its design!Nano-coating for a better wearing experienceThe shell of the FH1 is specifically nano-coated to make it scratch-resistant. When coupled with the UV-treated skin-friendly material that also makes up its shell, the FH1 is both durable and extremely comfortable to wear.Easy to plug in with right-anglesThe FH1's detachable cables (both 3.5 single-ended and 2.5mm balanced) were carefully designed based on users' feedback and their needs. For instance, the blue and red rings at the left and right ends of MMCX cable quickly indicate to the user which is left and which is right, while the spiral grooves at the same location allow one to easily and quickly grip the cable to change it. The MMCX cable is terminated in a right-angle plug so you can quickly and safely pull the FH1 out of your audio device.Over-the-ear design for an enjoyable experienceAfter much testing and feedback from a wide variety of users, we came up with an over-the-ear design that is not only ergonomic but also comfortable. With the FH1, you can easily get lost within your music for hours without fatigue.Red, green, blue and black, for a more colorful youTo be more in touch with your unique personality, the FH1 is offered in four different colors: Gunmetal Grey, Sky Blue, Chinese Red, and Emerald Green.Note: Image shown is for illustrative purposes only.
