This portable headphone amplifier is compatible with most headphones (best for impedance under 32 Ohms). It provides a powerful high-resolution audio experience through your headphones.
Specially designed for a wide array of digital devices such as cellphones, portable mp3 and iPod, which are naturally defective in low output impedance and low trust of audio output. With built-in USA high fidelity audio processing chip and patented audio processing technology, what you will hear is the highest quality music.
Features
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 butter worth 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 frequency is surgent, the sound with the design of internal resistance power supply is much transparent and the dynamic range is better.
