• FRA Direct-Radiation Balanced Armature Tweeter Brand-New Lithium-Magnesium Alloy Diaphragm - 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. 
• 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 Protocol - In 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. 
• 55ms Low-latency Game Mode Music/Game Mode Switching - Ultrasonic allows easy switching of dual connection modes under ordinary Bluetooth (AAC / SBC). In addition to the music mode, users can switch to game mode by tapping the faceplate four times, in game mode, the signal transmission delay is as low as 55ms, providing a more comfortable game experience 13. 
• Depth Wide-band ANC Single Feedforward with Lossless Sound Quality - In order to ensure that the sound quality is not affected when switching noise reduction. Ultrasonic abandons feedback noise cancelation, adopting a single feedforward solution that is more difficult to adjust, After repeated tuning and careful adjustment by skilled acoustic engineers, the combination of a brand-new flagship SOC ship and superior acoustic design achieves a excellent noise-canceling effect and lossless quality.
