The core of the BR21 series is a high-performance 32-bit RISC processor integrated with a dedicated Digital Signal Processor (DSP). The hardware is engineered to support Bluetooth 5.0 and above, with a specific focus on the A2DP, HFP, and HID profiles. What sets the "exclusive" driver set apart is the implementation of a proprietary protocol layer that operates beneath the standard Windows or Android Bluetooth wrapper. This allows for a significant reduction in the "buffer bloat" typically associated with standard Bluetooth audio, bringing latency down from the standard 150ms–200ms to sub-40ms ranges.
