Online Microphone Test

MicTesting123 started in a funny and unexpected way. During one of our team calls, several people were struggling with microphone issues — low volume, echo, background noise, and the usual chaos that happens before a meeting starts. Someone joked, "We should build our own mic test tool so we don't embarrass ourselves every time," and suddenly someone in the call stopped and said… "Wait, that's actually a great idea." What began as a simple experiment turned into something bigger. We realized that millions of people face the exact same problems every day — not knowing if their microphone, webcam, headphones, or speakers are actually working before an important call. So we built MicTesting123 — a fast, privacy-first, browser-based tool that lets you test everything instantly without installing anything. Whether it's a mic test, webcam preview, noise meter, echo test, or headphone check, our goal is to make sure your setup "just works."
