Common Microphone Problems
Why is my microphone volume so low?
This is a common issue. First, check your operating system's sound settings. In Windows, go to Settings > System > Sound > Input Properties and ensure volume is at 100%. Some microphones also have a physical "Gain" knob—turn this up.
My microphone has static or buzzing noise
Static often comes from "electrical interference" or a bad cable. Try plugging your mic into a USB port on the back of your PC (directly to the motherboard) rather than the front case ports, which are poorly shielded and often share grounding with USB power.
Browser cannot find my microphone
If the device list is empty, ensure your browser has permission to access devices. On macOS, you also need to check System Settings > Privacy & Security > Microphone and allow your browser.
Test microphone echo
Use our Playback Test feature above. Record yourself speaking, then play it back. If you hear an echo of yourself, it usually means your speakers are too loud and feeding sound back into the mic (loopback). Use headphones to fix this.
