Testing a speaker properly

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%.

Frequency 165 Hz Time left 0.0 s

💡 Point the speaker downward so gravity helps the water escape. Repeat 2–3 times if needed.

Speaker Diagnostic Test

Test your speaker health by playing tones at different frequencies. Report what you hear to get a diagnosis.

Preparation

Before you start

🧻

Wipe visible water

Dry the outside of your phone first.

🔽

Speaker facing down

Let gravity help pull the water out.

🎧

Disconnect Bluetooth

Ensure audio plays through the phone's internal speakers.

🔊

Volume around 70-80%

Never use earbuds. Turn volume up, but 100% isn't required.

Core Features

Fix My Speaker Functions

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.

Hover over the cards below to see the effect
💧

Eject Water

Clear trapped water from your phone in about 60 seconds. The steady 165 Hz vibration physically pushes trapped liquid out of the speaker mesh.

Eject Water

A steady 165 Hz tone — the sweet spot for maximum diaphragm travel — physically pushes trapped water out.

🧹

Clean Dust

Use our deep clean mode to act as a dust remover. Sweeping low frequencies shake loose stubborn dirt, sand, and lint.

Deep Clean

Sweeps across low frequencies (120–400 Hz) to shake loose lint, dust and stubborn droplets the single tone misses.

🎵

Restore Volume

Act as a volume booster for muffled speakers. Clear out blockages to restore heavy sound, loud bass, and crisp audio.

Test Sound

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 that moves water best.

Most speaker testing is done badly — by playing a familiar song and forming an impression. A repeatable method gives you information you can actually act on.

For a complete overview, see our full guide: Diagnosing what is actually wrong.

Use speech, not music

Music is a poor diagnostic for three reasons. Bass-heavy tracks mask exactly the mid and high frequency dullness that indicates blockage. Familiar tracks bias what you think you hear. And streaming introduces variables — bitrate, network, platform processing — that have nothing to do with your speaker.

Record a fifteen-second voice memo of yourself reading anything. It is a fixed local reference that never changes, and consonants are the giveaway: if s, t and f sounds are soft or smeared, something is in the mesh.

Test each driver separately

Play the memo and cover each grille in turn with a fingertip. Judging drivers in isolation is far more reliable than trying to separate them by ear while both play, because your brain merges them into one impression.

Test each audio path

Different combinations failing tells you whether the problem is a driver or a route.

Test at two volumes

30 percent and 90 percent. Faults that appear only at high volume indicate a driver reaching a mechanical limit. Faults present at both, proportionally, indicate blockage. This one comparison separates the two most common categories.

Use a high tone to measure progress

A 10 kHz tone is useless for cleaning but excellent for measurement, because high frequencies are attenuated most by mesh obstruction. Play it before and after cleaning. The difference is far more obvious than with any music.

Manufacturer diagnostics

Several makers ship genuine hardware tests that isolate the speaker for you — more reliable than listening. Samsung: *#0*# or Samsung Members. Xiaomi, Redmi and Poco: *#*#6484#*#*. OnePlus: *#808#. Vivo: *#558#. Realme: *#800#. Motorola: the Device Help app.

Record your baseline

Whatever you conclude, keep the reference memo. Comparing against a fixed file after each cleaning stage is the only reliable way to know whether you are making progress.

FAQ

Common questions

Will this void my warranty?

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.

How long should I run it?

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.

I cannot hear anything at all. What does that mean?

Blockage produces quiet, never total silence. If there is no sound whatsoever, check that media volume is up, that no Bluetooth device is connected, and that Do Not Disturb is off. If all three are clear, the fault is hardware.

It is still muffled after several tries. Now what?

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.

Can this damage my speaker?

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.

What this cannot fix

Our tool is great for water and dust, but it cannot fix physically blown speakers or electrical damage.
