Manufacturer's Description from Sennheiser

Introducing Esfera, Sennheiser’s innovative 5.1 surround microphone system which elegantly creates immersive surround audio from a single pair of X/Y microphones. Esfera simplifies workflows for broadcast professionals by efficiently capturing authentic ambience using just two audio channels, and converting this audio information to 5.1 at any point in the workflow - live or in post-production.
