Every tool you need to clear a muffled speaker and check your sound, in one place. Push out water, shake loose dust, and test stereo, mono, surround and bass right in your browser.
Dust, lint and pocket fluff slowly build up in speaker grilles and make sound crackly, quiet or dull. Our dust cleaning tool uses bass-heavy sound and vibration to shake loose particles out of the grille, so your speaker can breathe again.
Hold the speaker facing down while the tool runs so loosened dust can fall out.
Loosen dust and lint from a crackly or quiet speaker grille with bass-heavy music or vibration bursts, an adjustable frequency and left or right targeting.
Rain, a splash or a quick dip can leave water trapped in a speaker grille, making everything sound muffled. Our water removal tool plays a low 165 Hz tone that moves the speaker cone and pushes droplets out, with drip pauses built in.
Act quickly, wipe the device dry first, and never charge a wet phone.
Eject water from a wet phone, tablet or laptop speaker with a 165 Hz sound and vibration cycle, built-in drip pauses and safe auto stop.
Sound problems are not always caused by dirt or water. A swapped cable, a dead earbud, a device stuck in mono, a silent rear speaker or a weak subwoofer can all spoil your audio. Our sound tests play each channel and frequency on its own, so you can hear exactly what is working.
Play sound in the left, right or both channels, sweep across the stereo field, and catch swapped or reversed wiring.
Find out if your device is stuck in mono, hear stereo and mono side by side, and check mono compatibility.
Check every speaker in a 5.1 or 7.1 home theater on a room map, with real channel routing and a guided test all.
Find out how low your headphones, speakers or subwoofer go with a bass sweep, test tones, a polarity check and a range finder.
Match the problem you hear to the right tool and fix it in about a minute.
Cleaning tools fix what is blocking the sound. Testing tools tell you whether every channel is playing correctly.

Never wear headphones or earbuds while running a cleaning tool.
Rattling or distortion means you should stop and check the speaker.
Salt water, sugary drinks or no sound at all usually need a repair service.
Quick answers about our speaker cleaning and sound testing tools.

Low tones make the speaker cone move further than normal, which pushes water droplets and loose dust out of the grille. It works best soon after the problem starts and with the speaker facing down. It cannot reach water inside the device.
The tools use normal audio with set cycle lengths and automatic stops. Keep the volume moderate and stop if you hear rattling or distortion.
No. Use the speakers or headphones you already have. For the surround sound test, connect your computer to your receiver or soundbar by HDMI for real 5.1 or 7.1 output.
Most speaker problems are caused by water or dust. Start with a cleaning tool, then run a quick sound test to make sure everything is working.
