1. Adopting a nano crystal high-efficiency, environmentally friendly, and radiation resistant power supply system greatly reduces the harm of ionizing radiation to the human body while improving the efficiency of the power amplifier;

2. By optimizing the power supply system, the delicacy of mid to high frequency sounds and the density of low frequencies have been significantly improved, resulting in a more delicate and sweet human voice and a more robust and heavy bass;

3. This device is equipped with four sensitivity options to better solve the problem of inconsistent audio signal strength for users, and can achieve the same level of performance regardless of any audio source;

4. The circuit design of this machine has been optimized, with the maximum sensitivity adjusted to 2.19V to avoid damage to the backend system caused by strong signals such as musical instruments and current noise;

5. The appearance design is a fully heat dissipating panel, which avoids system protection caused by environmental overheating and maximizes system stability;
