How to get water out of your iPhone speaker with sound

Turn the volume all the way up, open Water Ejection in iSpeaker Cleaner and tap Start Ejection. It plays a loud low tone that rises from 165 Hz to 200 Hz over 30 seconds; the vibrating speaker pushes droplets back out through the grille they came in through. Hold the phone upright and run it once or twice more if it's still muffled.

Why a sound gets water out of the speaker

A single drop of water across the tiny holes of a speaker grille is enough. It damps the sound and blocks it, so voices and music come out muffled or crackling after rain, a pool or a splash.

What fixes it: a loud, low tone drives the speaker membrane back and forth a long way, many times a second. That movement pumps air straight through the grille and shakes the drop loose. Smartwatches rely on exactly the same trick for their water lock. Low notes do the work here because the membrane swings much further for bass than it ever does for a high whistle, which is why a high test tone on a wet speaker does little.

How to play the water eject sound on iPhone, step by step

  1. Dry the outside of the phone with a soft cloth.
  2. Press the volume-up button until the volume is at maximum. The app cannot change the system volume, which is why the instructions card says Set volume to max.
  3. Open iSpeaker Cleaner and tap the Water Ejection tab (the drop icon).
  4. Tap Start Ejection. The screen shows Ejecting Water..., the current frequency, a progress bar and a countdown, and the phone vibrates.
  5. Follow Hold device upright, with the speaker end pointing down or to the side so the water has somewhere to go. Keep the app open: leaving it or switching tabs stops the sound.
  6. When the countdown reaches zero the tone stops by itself. Play a song or a video and listen.
  7. If it is still muffled, wait a few minutes and run it again, as the card says: Repeat if necessary.

What the app plays, second by second

With Enable Frequency Sweeps on, which is the default, the tone glides in a straight line from 165 Hz to 200 Hz across the whole session. The number on screen updates once a second, in whole hertz.

45 s-191 Hz
60 s-200 Hz (ends)

Want a longer run? Change Cleaning Duration in Settings, anywhere from 10 to 120 seconds in 5-second steps. It covers the same 165-200 Hz range either way, just more slowly. Turn Enable Frequency Sweeps off instead and the tone just sits at 165 Hz for the whole run.

Free runs, and the free alternative

Free users get 2 runs of Water Ejection, total. Use them up and a banner says Free limit reached; tap Watch Ad for one bonus run, or go Pro and stop counting.

There's a free workaround worth knowing about. Smart Clean's Water program is unlimited and costs nothing: five 8-second steps at 80, 165, 200, 165 and 80 Hz, 40 seconds of sound total, at 80% of full level. Gentler than Water Ejection's full-level blast, but a solid second pass once your two free runs are gone.

Tips and common mistakes

  • Volume too low is the most common mistake. At half volume the membrane barely moves at all.
  • Take the case off if it covers the speaker holes — water trapped between case and phone will just keep coming back otherwise.
  • Don't tap the phone against your hand or blow into the grille; that can push water further in rather than out.
  • Two or three runs with a few minutes' rest between them beat one long run at full volume.
  • Still muffled after several runs and some drying time? The water isn't in the grille anymore. See the guide on muffled sound after water.

Questions and answers

How long should I play the water eject sound?
30 seconds, the default, handles most splashes. Still muffled? Run it again after a short pause rather than cranking the duration up to something huge. You can set anywhere from 10 to 120 seconds in Cleaning Duration if you want to.
Is there a setting on the iPhone itself to eject water?
No, iOS has nothing built in for this. The tone has to come from an app, which is what Water Ejection is for, and the Eject Water shortcut can turn that into a single step.
Should I hold the phone face down?
The app says upright. What actually matters is pointing the speaker end somewhere water can drip out — not into your palm.
Can I get water out of the charging port with sound?
No, there's no membrane in there for sound to push against. Let the port dry on its own and don't plug in a charger while it's still wet.
