Product Features: 1. Equipped with Bluetooth 5.4 and USB dual inputs, the computer can adjust EQ and real-time sound effects when connected online. 2. Original D-class amplifier chip, with a tested 6.2W power under a 4 Ω load, and the power is not falsely labeled. 3. Select high-quality resistive capacitive components, optimize high and low frequencies, and restore delicate and high fidelity sound quality. 4. Intelligent noise reduction+fine volume control, volume step by 1%, excellent signal-to-noise ratio performance. 5. Suitable for 3.7-5V power supply, mostly used for DIY self-made portable small speakers and car modification.

Performance Introduction: 1. Original power amplifier chip, with 1% TDH+N output at 4 Ω load and actual power of 6.2W without any false standard! 2. Two green gold high-frequency capacitors with better high-frequency performance and sufficient energy storage capacity. 3. Imported chip capacitors with sufficient capacity are used to ensure stable power supply and no leakage during shutdown of the chip. 4. Adopting a 1% thick sound resistor and imported coupling capacitor with higher precision to ensure sound quality. 5. The charging chip is equipped with reverse connection and surge protection, using high-quality charging control chips, with a charging current of up to 1000mA and high efficiency. 6. Equipped with the third-generation Acoustic TM intelligent noise reduction, manual switching can maintain high signal-to-noise ratio while maintaining amplifier output during startup, allowing for complete playback of both the beginning and end of the book. 7. Equipped with an infinite volume adjustment engine, the volume can be adjusted accurately to 1%, making the volume adjustment more precise.
