FEP is an electret, a type of material that's electrically charged and produces an external electrostatic field, similar to the way a magnet produces a magnetic field.

Logitech is promising that the Icepop will deliver enhanced “broadcast-quality” performance with its 10mm electret condenser mic.

The electret microphone, which is used by millions of people daily, “raises a challenge” for the inventor.

When he and Sessler created the electret microphone, it was assumed that the partners would quit their jobs and create a business mass-producing the microphones for companies around the world, but West wasn’t interested.

For example, James E. West, 84, obtained 11 patents when he was over 60 and is an inventor of the electret microphone.
