A few droplets in the mesh are enough to dull everything.

Sound familiar?
Tinny calls. Quiet videos.
Sound like it’s underwater.
Rain, spills, splashes
Calls crackle and the bass quietly disappears.
Months in a pocket
Lint and fibers pack into the grille, layer by layer.
Beach days and dust
Fine grit settles in and takes the high end with it.
It’s rarely the speaker. It’s what’s sitting in front of it.
Three steps · about 30 seconds
Face down. Volume up. Clarity.

Face the grille down
Gravity helps: water and grit leave the mesh instead of settling back in.

The membrane needs full throw. Voil checks your output and tells you when it’s too low.

Let the ritual finish
Each ritual takes about 30 seconds. Stubborn moisture may need two or three passes.
Frequencies
Every kind of dirt has its own note.
One random tone can’t do everything. Voil sweeps a range tuned to what’s stuck, while your phone’s haptics pulse in sync to shake it loose.

Honest about limits
Voil doesn’t open your phone, disassemble anything or repair serious liquid damage. If the phone was submerged or sound is badly distorted, go to an authorized service.
FAQ
Questions, answered.
How does Voil push water out of a speaker?
Your speaker’s membrane moves air when it plays sound. At the right frequencies and full volume, that movement — plus the phone’s haptics pulsing in sync — pushes droplets and loose debris out through the grille. Facing the grille down lets gravity help.
Is water eject really free?
Yes. The Water eject ritual is free. Voil Pro unlocks the other cleaning modes, the Hz lab and diagnostics.
How long does it take?
About 30 seconds per ritual. If moisture lingers, run two or three passes.
Will it work on my phone?
Voil runs on iPhone and iPad (iOS 15 or later) and on Android. Results vary by device and by how much water or dirt is in the grille.
Is it safe for my speaker?
Voil plays tones through your speaker the way any audio does at full volume, in short sessions. For light upkeep, use Gentle care. Keep the speaker away from your ear while a ritual runs.
My phone was submerged. Can Voil fix it?
No. Voil clears the speaker grille; it can’t repair liquid damage inside the phone. Power it off and take it to an authorized service.
How do I cancel Pro?
Subscriptions renew automatically unless turned off at least 24 hours before the period ends. Manage or cancel anytime in your Apple ID or Google Play subscription settings. After a reinstall, restore purchases from Voil’s Settings.
