Ultrasonic Hybrid Drivers TWS Earphone ANC LDAC Bluetooth 5.3 Headset 13mm Dynamic Driver

FRA Direct-Radiation Balanced Armature Tweeter Brand-New Lithium-Magnesium Alloy DiaphragmThe FRA balanced armature driver uses direct radiation from the diaphragm to handle high-frequency sound waves, thus reducing the standing wave generated by the sound nozzle structure of traditional balanced armature units, and delivering a wider ultra-high-frequency response.. 13mm Sapphire Diaphragm Full-Frequency Dynamic Driver Equidistant Transmission Two-Way Crossover Acoustic Structure"Ultrasonic" uses a 13mm full-frequency sapphire-coated dome composite diaphragm dynamic driver to handle the bass/mid-range and enhance sound reproduction in the relevant frequency bands. The sound wave transmission path follows the principle of equidistance and works with the crossover circuit to ensure the correct phase connection and restore the soundstage and timbre.

. LDAC High-Definition Lossless Audio Transmission ProtocolIn order to transmit high-resolution music files, Ultrasonic supports the widely used LDAC high-defnition lossless audio transmission protocol, which can transmit 24 bits/96 kHz at bit rates as high as 990kbps, amply meeting the dynamic range and broadband requirements of the hardware.
