condenser microphones (ECMs) do not follow a unified industry naming standard.

In this article, we explain common electret microphone naming rules and introduce ECMIC\u2019s structured model naming system. 1. Overview of Electret Microphone Model Naming Why Electret Microphone Model Names Differ by Manufacturer Because no global naming standard exists, each electret microphone manufacturer develops its own model naming logic to reflect design philosophy, production structure, and application focus.
