Flat Impedance Balanced Armature Earphone (FIBAE™) technology is world’s first, revolutionary, In-Ear Monitor design providing flat impedance and phase. By changing Balanced Armature driver character from inductive to resistive we solved one of the oldest problem in the industry – dependence on output impedance of sound source for correct earphone output. With FIBAE™ technology your earphones will always perform best from any DAP. Single and multi-driver configurations available.
