Water eject & speaker FAQ

Yes — for water trapped in the speaker grille, which causes most muffled sound after rain, showers or splashes. Low-frequency sound makes the speaker membrane push droplets out; you can often see them appear on the mesh.

Yes. A water eject tone is ordinary audio played at normal volume, like music. Keep the volume around 70–80%, avoid long runs at maximum, and stop if you hear harsh rattling.

Left alone, several hours to a full day. With a water eject tone, most of it comes out in 1–3 cycles of 30–60 seconds; heavy exposure may need up to 5 cycles plus air-drying.

No. Apple specifically advises against it because small rice particles can get into the iPhone. Tap it gently with the connector facing down, let it air-dry, and use a water eject tone for the speaker.

Low frequencies around 150–200 Hz work best; 165 Hz is the most widely used. Low tones make the speaker membrane move further on each stroke, pushing water through the grille.

No — a truly blown speaker is physically damaged and needs replacement. But many speakers that sound "blown" are just wet or clogged, and water eject fixes those. Test before you pay for a repair.

Only partly. You can play a water eject tone through connected AirPods, but their drivers are small and sealed, so the effect is limited. Dry them with a lint-free cloth, let them air-dry, then test left and right channels.

No. Only Apple Watch has a built-in water eject (Water Lock). On iPhone you need a water eject app like Clear Wave or a community Siri shortcut.

2–3 cycles of 30–60 seconds for splashes, rain or shower steam. Up to 5 cycles after submersion (pool, toilet), with a few minutes of drying between them. Stop when a stereo test sounds clear on both sides.

Clear Wave is free to download on iPhone and iPad. An optional in-app subscription (with a free trial) unlocks full access to all tools: water eject, stereo test, tone generator and dB meter.
