--- title: "Bluetooth Speaker Water Eject — Free JBL & Anker Cleaner" description: "Clear water and sand from a Bluetooth speaker with a free cleaning tone. Works on JBL, Anker, Bose, Sonos and UE. Includes beach and pool recovery steps." url: https://fixmyspeaker.me/bluetooth-speaker/ updated: 2026-09-14 --- # Bluetooth speaker water eject For JBL, Anker Soundcore, Bose, UE Boom, Sonos and any other portable speaker. Pair it to your phone, set volume to around three quarters, and run a cycle with the driver facing down. Interactive tool on this page: a speaker-cleaning tone generator with four modes — **Water Eject** (158–172 Hz sweep, 30 s), **Dust Removal** (200–400 Hz pulsed sweep, 30 s), **Deep Clean** (100–260 Hz slow sweep, 45 s) and **Smart Clean** (full cycle, 60 s). It synthesises the tone in the browser with the Web Audio API — no app, download, or account. ## Waterproof does not mean water-free Nearly every portable speaker sold today carries an IP67 or IP68 rating, and people reasonably assume that means water is not an issue. Then the speaker comes out of the pool sounding like it is underwater, and they think it is broken. It is not. The rating covers the electronics — the battery, the amplifier, the board. Those are genuinely sealed. But a speaker produces sound by moving air, and air has to get out, so the driver chamber is open to the outside by design. Water fills that chamber exactly as it would on any other speaker. A muffled waterproof speaker is a working speaker with water in front of the driver. Get the water out and it comes straight back. Nothing was damaged and nothing needs repairing. ## Pool and beach recovery 1. **Rinse it with clean fresh water first.** Counterintuitive, but right. Salt and chlorine leave corrosive deposits once they evaporate — a quick rinse dilutes them away. Only do this if the speaker is genuinely water rated. 2. **Drain it by orientation.** Turn it every which way and let water run out of the grille and any ports. Tap it firmly against your palm. 3. **Check the charging port flap is closed.** On most speakers that rubber flap is the one part that actually needs to be sealed, and the port behind it is not water resistant at all. 4. **Run a cleaning cycle, driver facing down.** Around three quarters volume. 5. **Rotate and repeat.** Portable speakers have drivers and passive radiators on multiple faces, so run a cycle for each orientation. 6. **Let it dry for hours before charging.** Overnight after a real soak. **Sand needs rinsing, not vibrating.** If there is sand in the grille, do not run a tone first. Sand is abrasive and hard, and vibrating it against a speaker membrane is how you turn a blocked speaker into a torn one. Rinse it out with clean fresh water, let it dry completely, and only then run a cleaning cycle. ## Passive radiators hold water If you have a JBL Flip, Charge or Xtreme — or any speaker with those distinctive moving plates on the ends — there is a specific trick worth knowing. Those plates are passive radiators: undriven diaphragms that move with air pressure inside the cabinet to extend the bass. They sit in shallow recesses that hold water very effectively, and because they are not driven by a voice coil, they do not vibrate as strongly as the main driver when you play a tone. Water sits there while you wonder why the speaker still sounds wrong. Hold the speaker with one radiator facing straight down, tap the opposite end firmly against your palm a few times, then run a full cycle in that orientation. Repeat with the other end down. This clears far more water than running cycles with the speaker sitting normally. ## Volume: more than a phone, less than maximum Bigger drivers need more energy to reach full excursion, so unlike earbuds you want real volume here — around three quarters is the sweet spot. Stop short of absolute maximum, though. A sustained sine wave is a much harder load on an amplifier than music, because music has constant peaks and troughs that let the amp and voice coil cool between demands. A continuous tone at full output for thirty seconds puts real sustained heat into a voice coil. Three quarters gets essentially all the cleaning benefit with none of that concern. ## Brand notes | Brand | Worth knowing | | --- | --- | | JBL Flip / Charge / Xtreme | Passive radiators on the ends hold water. Use the tap-and-tilt method above. | | Anker Soundcore | Turn BassUp and any EQ preset off in the app first — they filter the low end. | | UE Boom / Wonderboom | Cylindrical, so rotate through several orientations rather than just two. | | Bose SoundLink | Set the EQ to flat in the Bose app before running a cycle. | | Sonos Roam / Move | Disable Trueplay and any EQ adjustment in the Sonos app. | | Marshall / Sony | Turn off Extra Bass or equivalent — it reshapes exactly the range you need. | ## Frequently asked questions ### My JBL went in the pool and now sounds muffled. That is the normal, expected outcome for a waterproof speaker and it usually clears completely. The IP rating keeps water out of the electronics, but the driver chamber is open by necessity. Drain it, shake it passive-radiator-down, run the cleaning tone, and give it a few hours to dry. Chlorine is worth rinsing off with fresh water first. ### Why does a waterproof speaker still sound bad after getting wet? Because waterproof means the electronics are sealed, not that the speaker chamber stays dry. Sound has to get out through an opening, so water gets in through that same opening. A fully functional IP67 speaker will sound muffled straight out of a pool, and that is not a fault. ### There is sand in my speaker grille. Sand is the hardest case. It is heavy, abrasive and it wedges rather than resting loose. Never run a tone with dry sand in the grille — you are grinding abrasive particles against the membrane. Rinse it out with clean fresh water first if the speaker is water rated, let it dry, and only then run a cleaning cycle. ### Should I use a higher volume on a big portable speaker? Yes, up to about three quarters. Larger drivers need more energy to reach full excursion than a phone speaker does. Do not go to absolute maximum with a sustained tone though — a continuous sine wave is a much harder load on an amplifier than music is. ### Water is trapped behind the passive radiator. Common on JBL Flip and Charge models, where the passive radiators are on the ends. Hold the speaker with a radiator facing down, tap the opposite end firmly with your palm, then run a cycle in that orientation. Repeat with the other end down. ### How long should I let it dry before charging? At least a few hours, and overnight if it took a real soak. The charging port is the vulnerable part — most speakers have a rubber flap over it precisely because the port itself is not sealed. Make sure that recess is completely dry before you plug anything in. ## Other devices [Earbuds](https://fixmyspeaker.me/earbuds/) · [AirPods](https://fixmyspeaker.me/airpods/) · [Laptop](https://fixmyspeaker.me/laptop/) · [Android phones](https://fixmyspeaker.me/android/)
