TEQStone Headphone Amplifier, Little Portable Headphone Amp for Headphone to Improve Music Quality

The headphone amplifier is designed for most normal headphone. It can improve the music coming through the headphones.

The unit is specially designed to cope with the defect of the low output impedance and low trust of typical cell

phone's audio out.It adopts USA high fidelity audio processing chip with patented audio processing technology,

thus changing the phone audio quality,giving the best music enjoyment with the high fidelity stereo audio quality.

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.
