Working coaxially together, the two drivers create a more complete and coherent sound.\u003c\/li\u003e\n \u003cli\u003eCoaxial Acoustic StructureOLA II places the dynamic driver and BA driver within a coaxial acoustic structure. Different frequency ranges enter the ear canal along a more closely aligned acoustic axis, reducing imaging shifts caused by differences in sound-source position.
