Feature

●QCC5125 Latest Bluetooth technology: Qualcomms latest 5125 chip, dual DSP, and dual-core CPU architecture.to ensure the dual stability of Bluetooth audio and system operation, support LDAC/aptX Adaptive HD Bluetooth coding.
●SCCIntelligent switching: The SCC system controls independent DAC decoding, USB signal, power management, and an independent ear player. Unlike many integrated players, the independent ear player and decoding under the SCC system will make the sound clearer and restore so that the Bluetooth mode has the sound experience of wired mode.
●High and low gain adjustment: M4 has a switch gain function, turn on the red high gain, enter the high-resolution lossless state, make the song sound more transparent, and restore. The sound and instrument performance are more three-dimensional, as if you were in a live concert.
●Transparent design stronger signal, more stable: As the flagship decode of MUSE HiFi, the transparent material before and after, the metal frame will maximize the Bluetooth signal release and the NFC function is more stable.
●Independent HiFi architecture:M4 is equipped with ES9038Q2M flagship decoding chip, can support 384ksampling rate and DSD256 hard solution, in USB DAC mode, with MQAplayer, can support MQA rendering, support MQA 8x expansion.
