FiiO FH19 Flagship Hybrid In-Ear Monitors Black

Push-pull dual dynamic driver units: The push-pull dual dynamic driver unit developed jointly by FiiO and Tokyo Acoustic Corporation features two 13.7mm high-magnetic dynamic driver units. The diaphragm is made of PU+DLC composite material and is arranged in a opposing vertical configuration, generating twice the driving force through push-pull action. This design results in a smaller diaphragm displacement, reducing intermodulation distortion and producing cleaner sound. Custom Knowles enhanced mids BAs: By adding acoustic vents to the rear cavity of the driver, the mid-frequency driver gains more sound energy compared to typical mid-frequency drivers. This further taps into the inherent advantages of the mid-frequency driver, resulting in rich and dense vocal reproduction with a captivating magnetic allure. Suspended voice coil: The design of the suspended voice coil involves routing the voice coil leads directly from the center hole underneath the diaphragm, allowing the leads to float in the gap. This eliminates the need for additional contact and extra adhesive load, resulting in more uniform and smooth diaphragm vibration. It also eliminates interference from other factors, allowing the original acoustic characteristics of the diaphragm to be fully unleashed. Titanium+7000 series aluminum construction: The middle frame is made of pure titanium metal, which provides excellent rigidity and corrosion resistance, effectively protecting the headphone body. The shell is made of 7-series aerospace aluminum material, ensuring the strength and lifespan of the body while reducing the weight of the headphone body. High-purity monocrystalline silver cable: Each of the 8 strands consists of 28 wires totaling 224 wires. Each individual wire is insulated with enamel, and the cable is twisted in Litz braids. The outer sheath is made from imported transparent eco-friendly TPU, enhancing its transparent appearance. Additionally, this material effectively prevents the cable from yellowing over extended use and becoming stiff in low-temperature environments.
