Important information regarding this tool
The microphone hole at the bottom of your smartphone is incredibly small. Because of this, water surface tension can easily trap a single drop of water inside the hole, blocking the acoustic mesh completely.
If you've recently dropped your phone in the sink or pool, and people say you sound like you're underwater on phone calls, your mic is likely blocked. Use our quick recording tool above to hear exactly what the person on the other end of the call is hearing. If it sounds muffled, try our Water Ejector to push the water out.

Common questions from our users
Absolutely not! The audio recording happens 100% locally inside your own browser. We don't have any servers, and your voice is never uploaded or saved anywhere. It disappears as soon as you refresh the page.
Smartphones actually have multiple microphones! There is usually one at the bottom (for calls) and one near the camera (for videos). If videos sound fine but calls are muffled, it means only your bottom microphone is blocked with water or dust.
If the recorded audio sounds like static, robotic, or completely silent even after drying for 24 hours, the hardware may be permanently damaged.
Your browser requires explicit permission to access your device's microphone for privacy reasons. We only use it for the 5-second local recording.
Yes, bulky, rugged, or poorly designed phone cases can sometimes cover the microphone holes, making you sound muffled. Try recording without the case.
Absolutely. Pocket lint and dust can compact into the microphone grill over time. Try using a soft-bristled brush to gently clean it.
By default, browsers access the primary bottom microphone (the one used for regular phone calls), which is the most likely to get submerged in water.
