Microphone problems and their limits

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.

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 range where diaphragm travel is greatest.

This is worth stating immediately: acoustic cleaning does nothing for a microphone. There is no driver to vibrate, so no tone can push anything out. The available options are narrow.

For a complete overview, see our full earpiece guide.

Why no tone works

Speaker cleaning works because the speaker itself moves. Its diaphragm travels back and forth, pumping air against whatever is blocking it. A microphone has no such driven element — it is a passive sensor. Playing sound at it does not move anything mechanically, so nothing gets expelled. Tools claiming to clean microphones with tones are describing something that does not happen.

Working out which microphone is affected

Most phones have two or three, in different locations, used in different combinations by different apps. That is why symptoms seem contradictory. Test in this order:

  1. Voice memo — usually uses the bottom microphone.
  2. Video recording — often uses the rear or top microphone.
  3. Speakerphone call — typically uses the top microphone.
  4. Normal handset call — usually the bottom microphone.

Whichever test fails identifies the affected unit.

What callers hear

A blocked microphone makes you sound distant, thin or hollow rather than simply quiet. Noise cancellation can make it worse: if the phone is comparing inputs from two microphones and one is obstructed, the processing may misjudge which signal is noise and suppress your voice.

The only safe cleaning

A microphone port is a pinhole covered by extremely fine mesh — considerably more fragile than a speaker grille. A soft dry brush across the surface is the limit. Nothing inserted into the hole. A pin punctures the mesh and can damage the element behind it, converting a cleanable problem into a replacement.

Rule out software first

Check that no app has had microphone permission revoked. Check that a case does not cover a mic opening — this is common and easily missed. Restart the device to clear a stuck audio route. And try a different app, since a single misbehaving app can hold the microphone.

After water exposure

Moisture in a microphone port usually resolves as the device dries, over 24 to 48 hours in moving air. Do not attempt to speed it up with heat, and do not insert anything absorbent — paper and cotton shed fibres that stay behind and make things worse.

FAQ

Common questions

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.

Can I use headphones or earbuds while it plays?

No — and this matters. The sound has to travel through the blocked speaker to do anything, so any connected Bluetooth or wired device defeats the purpose entirely. Disconnect everything first.

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.

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.

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.

What this cannot fix

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