Special Feature 
1.Positive and negative double power technology 
Built-in single power supply circuit effectively suppress background noise,thus achieving a best stereo audio effect. 
2.High frequency dynamic compensation tuning circuit network 
Built-in Butterworth circuit design can make up these shortages of mobile phone music,such as the darkness of high frequency and weakness of low frequency 
3.Low distortion calculation amplifier 
THD: THD+N is 0.006% 
Free output capacitance,making the reference of ground level as the output design,the low prequency is surgent,the sound with the design of internal resistance power supply is much transparent and the dynamic range is better.
