Although the phone lacks a 3.5mm headphone jack, the stereo speakers provide rich audio quality, supported by 24-bit/192kHz Hi-Res audio. Connectivity options are comprehensive, including Wi-Fi 6, Bluetooth 5.1, NFC, and an infrared port, ensuring wide compatibility with networks and devices. The absence of FM radio might disappoint some users, but the variety of other communication technologies makes up for it.
