FiiO FH5 Quad Driver Hybrid In-Ear Monitors Immerse yourself in an endless stream of music. Value for money Compared to other IEMs in the same price range, the FiiO FH5 performs well, no matter from the aspects of design, structure, driver allocation, processing technology, or even the cable and accessories. Hi-Res Audio certification The FH5 has been certified by the Japan Audio Society to be "Hi-Res Audio" capable. This means that the FH5 is capable of a frequency 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 intended. MMCX connectors give you more ways to play The connectors on the FH5's cable make it as easy as possible to connect to other devices with its elbow plug and to easily be charged the MMCX connectors are coloured co-ordinated to easily identify left and right channels. Easier insertion into your ear The shell of the FH5 is an aluminium alloy precisely machined with CNC technology, ensuring that it will continue to last for years to come. The FH5's shell design is also reminiscent of custom in-ears, which not only provide an extremely comfortable fit but a stylish accessory to wear. The crescent shape of the FH5's are specifically designed to conform to the ear and provide a snug, comfortable fit. The isolation of this design allows you to focus on your music even if you are on a busy street or next to a raucous party. Knowles Balanced Armature +10mm Polymer Nanocomposite Dynamic Driver The FiiOFH5 employs a hybrid driver design that combines the best of balanced armature and dynamic drivers for an addictive sound. Quad Driver Hybrid In-Ear Monitors Like today's most advanced exotic sports cars, the chassis and body must be extremely solid to extract maximum performance. Only a solid chassis could create a pure and clean sound. Using the TRISHELL patented structure, the shell of FH5 is made of Aluminium Magnesium Alloy processed by five-axis machining. Using three screws for the most stable three-point fixing could minimize unnecessary resonance and distortion to get a pure and solid sound. Exotic-inspired S.TURBO technology for a burst of pure, raw lows The FiiOFH5’s low-frequency sound tube adopts FiiO’s patented S.TURBO (short for Sound Turbo) acoustic structural design. With its specially designed turbine-inspired design that makes clever use of the physics of sound waves, you get meaty, deep bass that is more than capable of letting you feel the music. S.TURBO also filters out unnecessary mid and high frequencies produced by the bass driver ensuring a more seamless transition between the lows and highs. Low frequencies are deftly handled by a 10mm polymer nanocomposite dynamic driver, providing bass extension and quality beyond what you think is normally possible. Mid frequencies are produced by the Knowles ED30262 balanced armature driver, while high and ultra-high frequencies are created by the Knowles 31082 (greatly improved over the 30017) – specifically tuned to squeeze every last bit of performance from them. These four drivers per ear combine to provide thunderous lows, lush vocals, and sweet highs for a sound that you won’t forget anytime soon. A flexible sheath on the outside hides a robust core The high purity mono-crystalline silver-plate copper wire makes up the FH5's hybrid cables and effectively minimises distortion and signal transmission loss for the best sound quality possible. These wires are braided together in an environmentally friendly, transparent TPU sheath that allows you to appreciate the craftsmanship involved in making the cable.
