GOWE Portable Headphone AMP & battery AMP& NE Headphone Amplifier

Features: 1. Professional design, suitable for driving low-impedance headphones high school; 2. With high and low impedance selector switch, gain selector switch, to adapt to a wider range; 3. No channel input and output coupling capacitor, a wider frequency response; 4. Special compensation for more perfect sound, low dive + sound field expansion of compensation to close the compensation, is a wide adaptability of high-fidelity headphone amplifier; 5. In parallel with multiple power tube output stage, the output impedance is low, control and strong. High-impedance state to start boost circuit, the output distortion with high voltage and high impedance headphones to meet the demand-driven; 6. The volume of imported high-quality potentiometer fever potential, ensure sound quality; 7. High-performance lithium polymer battery, with full protection; 8. Built-in smart charging circuit voltage can be while listening to music while charging; 9. Large reservoirs + and more ultra-low resistance solid capacitor decoupling design, power is more pure.
