The core solution is the CT7601+American ES9038Q2M high-precision decoder. Chip THD+N refers to 120dB, with a total harmonic distortion as low as 0.001%. This is thanks to the 100M active low phase noise crystal oscillator and fully optimized PCB circuit design The sound analysis power details are very good, and it can drive general head mounted devices or small earplugs In addition to connecting to a mobile phone, it can also be connected to a computer or PC for use as an external USB sound card. The sound quality is comparable to a desktop decoder priced at 400-1000 yuan.
