Audio and Connectivity
Despite lacking a 3.5mm headphone jack, the S99 supports Hi-Res audio at 24-bit/192kHz, delivering high-quality sound through supported devices. Connectivity options are modern, including dual-band Wi-Fi, Bluetooth 5.1, NFC (availability may depend on the region), and FM radio. The positioning system is robust, supporting GPS, GLONASS, GALILEO, and BDS for precise navigation.
