165 Hz is the most popular frequency for clearing water from phone speakers. It is low enough to move the speaker cone a lot, but high enough for small phone speakers to play clearly.
Why this frequency?
Small speakers struggle with very deep bass. Below about 100 Hz, they barely move air. At around 165 Hz, they move strongly and push water drops toward the grille.
How to use it
- Remove the case and dry the phone.
- Set volume to max.
- Hold the speaker facing down.
- Play the 165 Hz Water Eject tone for 60 seconds.
- Test the sound and repeat up to 3 times.
Steady vs. pulsing tones
Our tone pulses gently, which shakes drops loose instead of only pushing them. Many people find it clears water faster than a steady tone.
Other useful frequencies

You can play any of these in the Tone Generator.
Is it safe?
Yes. 165 Hz is within your speaker’s normal range. Stop if you hear constant, harsh rattling.
FAQ
Do I need headphones?
No. The point is to move your phone’s own speaker, so play it through the speaker.
