FiiO/JadeAudio JH5 1DD+4BA Hybrid 5 Drivers HiFi in-Ear Monitors Earphone, Detachable 0.78mm 2 Pin Cable 3.5mm Plug for Audiophile/Musician (Black) Higher performance: With the goal of presenting music from genres as diverse as classical to pop all in a high-fidelity manner, JH5 is a 10mm carbon-based dynamic driver which is seamlessly connected to the custom balanced armature drivers covering medium to ultra-high frequencies thanks to the drivers being separated into three independent chambers.The FIIO JH5 is truly an affordable IEM with a highly precise sound that truly lets you experience how good dynamic-BA hybrids can get. 1DD+4BA Hybrid Structure: JH5 Adopting10mm carbon-based dynamic driver & dual-cavity internal magnetic circuit dynamic driver of N52 magnet+ Four custom BA drivers per ear. Utilizing high-precision 3D printing cavities. Come with the 392 wires of silver-plated copper headphone cable which increases the conductive area and improves high-frequency detail. Three independent driver chambers: A three-channel independent chamber acoustic structure was developed for JH5: the drive units of each frequency band are assigned to channels with different characteristics, and independent chambers are created for the units corresponding to each frequency band; the sound wave interference between the units is fundamentally reduced. to reduce distortion. Custom ultra-high frequency BA driver: JH5 has two custom-made ultra-high-frequency moving iron units in the ultra-high frequency, which allows FiiO JH5 to have stronger ultra-high frequency extension; in terms of human hearing, it can accurately capture the moment when the strings are plucked and feel the sound. An immersive and realistic listening experience. Custom medium and high frequency BA drivers:Two mid- and high-frequency moving iron units are customized: achieving a smooth and flawless transition between hoop irons, and allowing the transition to fully adapt to human ears, making the sound field more natural and the overall tone smoother. Dual cavity dynamic driver: The dynamic speaker unit adopts a double-layer cavity design, and is equipped with a damping control system in both the inner and outer cavities to accurately control the damping of the air flow to reduce the nonlinear distortion of the unit, change the compliance performance of the diaphragm, and achieve high-quality The low-frequency dive and sense of speed make the dynamic coil more "circular".
