Tap the button below. It plays a low‑frequency sound that vibrates the speaker and pushes trapped water and dust out of the grille. Turn your volume up to about 80%.
💡 Point the speaker downward so gravity helps the water escape. Repeat 2–3 times if needed.
Manually tune the exact Hz frequency for your speaker cleaning. Drag the slider to find the resonant frequency of your device.
Dry the outside of your phone first.
Let gravity help pull the water out.
Ensure audio plays through the phone's internal speakers.
Never use earbuds. Turn volume up, but 100% isn't required.
Our tool is designed to target the three most common speaker issues using precise acoustic frequencies. Whether your phone took a dive or just sounds muffled from pocket lint, here is how we fix it.
Clear trapped water from your phone in about 60 seconds. The steady 165 Hz vibration physically pushes trapped liquid out of the speaker mesh.
A steady 165 Hz tone — the sweet spot for maximum diaphragm travel — physically pushes trapped water out.
Use our deep clean mode to act as a dust remover. Sweeping low frequencies shake loose stubborn dirt, sand, and lint.
Sweeps across low frequencies (120–400 Hz) to shake loose lint, dust and stubborn droplets the single tone misses.
Act as a volume booster for muffled speakers. Clear out blockages to restore heavy sound, loud bass, and crisp audio.
A clean 440 Hz reference tone so you can hear whether your speaker sounds clear again after cleaning.
Perfectly safe. These are ordinary frequencies your speaker already plays during music. The tool never exceeds normal listening levels — it just concentrates the energy at the frequency range where diaphragm travel is greatest.
165 Hz appears everywhere as though it were a physical constant. It is not — it is a reasonable average, and knowing what it is averaging tells you what to do when it does not work.
For a complete overview, see why low frequencies clear speakers.
Every speaker has a resonant frequency — the point where the moving system naturally wants to oscillate, and where a given input produces maximum diaphragm travel. It is set by three things: the mass of the diaphragm, the stiffness of its suspension, and the volume of the sealed cavity behind it. All three vary between manufacturers and between models from the same manufacturer.
Small smartphone drivers cluster somewhere between roughly 120 and 400 Hz. 165 Hz sits low in that band, where excursion is largest while still being reproducible by a small driver. It is a sensible default for the population of devices, not a targeted value for yours.
Apple Watch's water-eject function has an advantage no general tool has: Apple knows the exact resonant frequency of the driver it designed. It can target it precisely. A third-party tool cannot, which is the entire reason a sweep exists as an option.
Two possibilities. Either your driver's resonance sits meaningfully away from 165 Hz — in which case a sweep across 120–400 Hz will pass through the right point — or the blockage is not the kind that responds to sound at all. Try the sweep first. If that also produces nothing across three cycles, the problem is not liquid or loose debris.
In practice, orientation and volume affect results more than frequency does within the useful band. Grille facing down, angled about 45 degrees, at 70–80 percent volume, will outperform a perfectly tuned frequency played flat at maximum volume. Get those right before worrying about the exact number.
Bluetooth speakers and laptops have bigger diaphragms and heavier moving mass, so their resonance is lower — often well under 100 Hz. On those devices 165 Hz is above the optimum, and a downward sweep is more useful than a fixed tone.
No. The frequencies used sit inside the range your speaker already reproduces whenever you play music, and the tool runs at moderate volume rather than maximum. The one genuine caution is earbuds: never run ejection tones into in-ear devices while you are wearing them.
No. Around 70 to 80 percent is the practical sweet spot. Maximum volume on a restricted diaphragm produces distortion rather than more displacement, and adds avoidable stress to the driver.
Thirty to sixty seconds per cycle, repeated two or three times with short pauses. Running it continuously for many minutes adds nothing once the accessible liquid is out, and only heats the voice coil.
Stop. If three cycles produce no improvement at all, the cause is not blockage. Check the symptoms on our guide to when a sound tool will not help, and have the device inspected rather than continuing to run cycles.
Playing an audio file does not modify your device or open it, so the tool itself has no warranty implication. Note separately that liquid damage is usually excluded from standard warranty cover regardless.
Our tool is great for water and dust, but it cannot fix physically blown speakers or electrical damage.
