Feature:

The voice was sweet ,soft and clear
Neodymium strong magnet Beryllium copper Silk edge membrane，Add characteristics of refined magnetic fluid, high efficiency neodymium magnetic intensity magnetic, ingredients cotton noise elimination, refreshing and listening! add protective net.
The secret-made beryllium copper film contains 16.7% beryllium and 83.3% copper, which can make the film very thin and less easily broken than pure beryllium film.The thickness is only 0.015mm.0.03 0.04 with titanium membrane is aluminum film is far from level. With patent with metal ball membrane structure, so has strong ability of analysis and the metal film with silk edge beryllium copper film properties, resolving power is strong, fresh and silky, resistant to listen to, for a long time to tire, there is no high frequency rush rush, extension and better frequency on-line direct 40 k, exquisite and clear, detailed performance ultra clear, no spikes don't rob ear, and the secret plate of metal ball units.
