About the R6 Pro II
The HiBy R6 Pro II is a portable digital audio player running an open version of Android 12, built around a Qualcomm Snapdragon 665 processor with 4 GB of RAM and 64 GB of internal storage. Its digital-to-analog section combines an AKM AK4191EQ digital processor with two AK4499EX DACs. A switchable Class A/Class AB amplifier circuit feeds separate 3.5 mm and 4.4 mm headphone and line outputs. The player also supports USB DAC and coaxial digital output, two-way Bluetooth, Wi-Fi, microSD expansion, and high-resolution playback up to PCM 1536 kHz/32-bit and DSD1024. This describes the original R6 Pro II, not the later R6 Pro II 2025 edition.
