Mi In-Ear Headphones – Gold The fusion of one dynamic and two balanced-armature drivers offers high design flexibility. Therefore our earphones secure sound with ultra-low distortion, accurate mid and crystal-clear high note. Hybrid technology is the combination of one dynamic driver and two-way balanced-armature (BA) drivers. The combination of dynamic and BA drivers, and their relative position to each other in the housing, allowed us to develop the smallest three-way in-earphones that offer a true reference-quality sound. The balanced-armature will be handling on high frequency audio while dynamic driver will handle the low frequency audio thus providing a more 3D surround effect. The secret weapon of this hybrid earphone is Luca Bignardi the audio engineer! He had nominated for the Latin Grammy and won Grammy and Latin Grammy Awards. Professionally tuned earphone to maximise your enjoyment when listening to music.
