Quick Installaon Guide

Brief introducon:

E01 is one kind of desk-top headphone Amplifiers, whose main chip adopts TI
audio professional IC, with the advantage of low noise and distoron.
Users can choose the volume that suitable for themselves.
High-current output can easily drive various headphones with different
impedance. All of these things can make you easily enjoy the high quality and
high sense of presence music.
