FiiO E11

●Small size, easy to carry
●Built-in high-performance lithium battery, standard BL-5B model, convenient to replace.
●High efficiency and low noise power boost, precision separate pressure for dual-supply, satisfy large dynamic signal.
●Heavy current three channels amplified circuit, effective to lower the output impedance.
●Volume control use the closed APLS potentiometer, ensure the low noise and good channel balance.
●Three levels bass boot, can meet different needs of the sound.
●Two levels gain option, suitable for using with different phones.
●Two levels working voltage option, satisfy different needs of the trends (hidden design)
●Auto-lock protective circuit, will cut off automatically when abnormal cases happened to protect the headset and your hearing.
●Charge priority function: This machine will stop working immediately when charge it, meanwhile, red light is on and blue one off. When the battery has been charged completely, please unplug the external source, this machine begin to work again, at the same time, the red light off, blue light on.
