FiiO FH5 Earphones HiFi Quad Driver Hybrid for iOS and Android Wired  (White, In the Ear)

The lows are deftly handled by a 10mm polymer nanocomposite dynamic driver, the mids are produced by the Knowles ED30262, while the high and ultra-high frequencies are created by the Knowles TWFK-31082. These four drivers per ear combine to provide thunderous lows, lush vocals, and sweet highs. The FH5???s patented TRISHELL(stands for TRIPLE + SHELL) structural design ensures that this is the case, with a 5-axis CNC machined aluminum-magnesium alloy rear shell, body, and front covers fixed tightly together with multiple screws ??? greatly reducing excess resonance and distortion. The FH5???s low frequency sound tube adopts FiiO???s patented S.TURBO (stands for Sound Turbo) acoustic structural design, which makes you get meaty, deep bass. 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. The shell of the FH5 is of aluminum alloy precisely machined with CNC technology, ensuring that it will continue to luster for years to come. The FH5???s shell design is also reminiscent of custom in-ears, which not only provides an extremely comfortable fit but also shines as a stylish accessory to wear. MMCX connectors + 3.5mm single-ended cable made by high-purity monocrystalline silver-plated copper wire + 12 pairs / 4 different sets of ear tips for balanced, enhanced bass and enhanced vocals sounds + foam type.
