Fiio E12 Mont Blanc

Professional operational amplifier with High Fidelity.
Gold Operational amplifier (OPAMP) Pair:
Mont Blanc adopts the high-performance OPAMP combination OPA1611 and LME49600 which was specially designed for Hi-Fi audio products by the TI Company located in America. Of the two, OPA1611 serves as the amplifier, while LME49600 plays the role of currency outputting. The uttermost performance of the two OPAMP can achieve near-zero distortion at 0.000015%.
Classical circuit framework.
Guaranteed sound fidelity.
As always, OPAMP circuit employs mature while classical design with the combination of operational amplifier and buffering which results in perfect balance between high-performance sound fidelity and long-lasting durability. With the addition of high quality well-chosen audio devices, such as WIMA capacitor, ALPS potentiometer and battery at high-frequency while low-impedance, it makes the sound of our Mont Blanc to be low-distortion as well as low internal resistance and quality to rival the glory of the world's most famous piano Steinway.
Innovative power design.
High Voltage Supply at 22V.
The built-in Li-polymer battery with large capacity imbedded in Mont Blanc is capable of providing strong power supply.  On one hand, it enables the OPAMP's high performance to be guaranteed; on the other hand, it can meet the large dynamic range that is required in boosting big headphones with high impedance. The total maximum output power can reach as high as 850mW.
USB smart charging.
The quickest and most convenient of its kind.
To bring convenience to all the end-users, we get the 5V USB boosted to 14V so as to get the built-in battery recharged. Therefore, users can feel free to charge it by means of computer, mobile phones or laptops with 5V currency via USB port.Mont Blanc will automatically adjust to the proper charging currency according to the PC USB port and other chraging output currencies to get the battery recharged as soon as possible.
User-friendly functional indicator.
Keeping everything under control.
The charging-indicator makes the Mont Blanc much more user-friendly. It adopts the popular respiration lamp effect which would reflect the charging speed. High blinking requency indicates quick charging, while low blinking frequency indicates slow charging. In order to cater to different headphones with various impedance, styles and sensitivities, Mont Blanc provides gain adjusting and bass boosting functions which enable you to have flexible customized usage. The added simulation of Speaker Sound Field lessens the headphone's in-head effect.High damping rotational potentiometer can avoid error-operation during movements. Secured output relay is capable of preventing booting pop noise and protecting headphones and player in case of any abnormalities.
Super slim wire-drawing workmanship.
Sophisticated metal fashion.
Exquisite metal wire-drawing effect has been applied to the surface, and the carefully designed volume knob secures a comfortable and sophisticated feeling. Just like the iPhone, apart from the two concealed screws, the Mont Blanc has a stylish, seamless design.
