For maintenance, roughly once a month is plenty. More often if you exercise heavily, work outdoors, or live somewhere humid or dusty. There is no benefit to daily use on a speaker that sounds fine.
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.
Gently vibrate trapped water, earwax, and debris out of your headphone using calibrated sound waves.
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.
Over-ear headphones have larger drivers behind protective foam, so the causes of muffling are different from earbuds — and the most common one is not the driver at all.
For a complete overview, see what to check on earbuds.
Foam pads compress and harden over time, which changes the seal against your head. That seal is what produces bass — a compromised one lets low frequencies escape, leaving audio thin and distant. People routinely diagnose this as a failing driver when it is a consumable part.
Press the cups gently against your head. If bass suddenly returns, the pads are the problem and replacing them costs a fraction of new headphones.
Dust and hair collect on the fabric or foam covering the driver. A soft dry brush across it lifts most of it. On many models the pads detach, exposing the grille for proper cleaning — check whether yours are removable before forcing anything.
On wired models these are common and distinctive. Audio cutting in and out when you move the cable indicates a broken conductor, usually at the plug or the Y-split. Test by flexing gently near the plug while audio plays. Many over-ear headphones use detachable cables, which makes this a cheap fix — try a different cable before anything else.
Distortion that worsens with volume, or a rattling quality, indicates a damaged diaphragm. Not blockage, and cleaning will not help. Lowering the volume making it largely disappear is the confirming test.
Test on a different device before concluding anything. A volume limiter, an aggressive equaliser, a low-quality Bluetooth codec, or Headphone Accommodations on iOS all produce muffling indistinguishable from a hardware fault.
On wireless models, the codec in use affects quality noticeably. If they sound worse on one device than another, the codec negotiated is likely different rather than anything being wrong.
Over-ear drivers are not enclosed in a narrow grille that traps liquid. Their problems are pads, cables and source settings. Cleaning tones have little to offer here — and should never be run at volume with the cups on your head.

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