Features:
1. Equipped with Bluetooth 5.4 and USB dual inputs; when connected to a computer, it supports adjustable EQ and real-time audio effects.
2. Features a genuine Class D amplifier chip, delivering a measured power output of 6.2W at a 4Ω load—power ratings are accurate.
3. Carefully selected high-quality resistors and capacitors optimize both high and low frequencies to reproduce delicate, high-fidelity sound.
4. Intelligent noise reduction + precise volume control with 1% volume increments and excellent signal-to-noise ratio.
5. Compatible with 3.7–5V power supplies, commonly used in DIY portable speakers and car audio modifications.
Performance Overview:
1. Genuine amplifier chip delivering a real-world rated output of 6.2W at 1% THD+N under a 4Ω load—no exaggerated power ratings!
2. Two green-gold high-frequency capacitors provide superior high-frequency performance and ample energy storage capacity.
3. Imported surface-mount capacitors with sufficient capacity ensure stable power supply during chip operation and prevent leakage current when powered off.
4. Features high-precision 1% thick-film resistors and imported coupling capacitors to ensure superior sound quality.
5. The charging chip includes reverse polarity and surge protection; it uses a high-quality charging control chip with a charging current of up to 1000mA for high efficiency.
6. Equipped with third-generation Acoustic™ Smart Noise Cancellation; after manual switching, it maintains amplifier output upon startup while preserving a high signal-to-noise ratio, ensuring that every word—from the beginning to the end—is played clearly when listening to audiobooks.
7. Features a stepless volume adjustment engine, allowing volume control with 1% precision for more accurate adjustments.
