The Schoeps KA 40 sphere accessory (40 mm diameter) is meant for use with Schoeps omnidirectional microphones. It is placed around the microphone capsule.

The KA40 is an acoustic filter that off-axis provides a larger shadowing at medium (1-4 kHz) frequencies. As long ago there were no high-quality pressure gradient microphones, this was the only way to produce directivity. For example, the vintage Neumann M 50 microphone also had such an acoustic filter.

The KA40 creates the illusion of closer placement.

The higher directivity is also advantageous in a Decca tree because it creates some level differences in this otherwise purely time-of-arrival-based stereophonic microphone technique.
