The primary function of the HiBy R2 II is to play digital audio files with high performance and fidelity. It acts as a standalone music player, allowing users to store and access their music library on a Micro SD card. Beyond its core playback capabilities, the R2 II offers versatile connectivity options, enabling it to function in various roles within an audio setup.

It can serve as a USB DAC, converting digital audio signals from a computer into analog output for headphones or speakers. This feature allows the R2 II to enhance the audio quality of your computer's sound.
