Audio and Connectivity
Although the absence of a 3.5mm headphone jack may disappoint some audiophiles, Oppo compensates with high-resolution audio support, both wired and wireless, through its stereo speakers that deliver clear and rich sound. Connectivity options on the K12 are robust, including Wi-Fi 6, Bluetooth 5.4, NFC, and an infrared port. The phone supports multiple positioning systems, ensuring accurate navigation regardless of geographic location.
