Note: Moondrop UltraSonic True Wireless TWS Earphones Earbuds Ultra Sonic 1 Year Official Warranty In order to fully restore the broadband signal, Ultrasonic utilizes the LDAC high-definition audio transmission protocol. And it's equipped with a newly-developed FRA direct-radiation balanced armature driver, and a 13mm full-frequency dynamic driver. The 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, in terms of the 13mm full-frequency sapphire-coated dome composite diaphragm dynamic driver, it handles the bass/mid-range and enhance sound reproduction in the relevant frequency bands. To transmit high-resolution music files, Ultrasonic supports the widely used LDAC high-definition 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. The LC3 encoding and decoding protocol supporting the new generation Bluetooth LE Audio, when paired with devices that are also compatible with standard LC3, achieves not only much lower latency than traditional Bluetooth but also excellent high-fidelity signal transmission.
