In this case, the battery will be fully powered by USB, preventing overcharging and overdischarging. The device also delivers a powerful 650mW output capability while not consuming the smartphone's battery. With lower latency, more stable transmission, and better compatibility than regular USB chips, the device supports 768kHz/32bit, hardware decoding for DSD512, and full MQA decoding. It also features PEQ developed on this platform, allowing adjustments via both the app and web in
