Even a fully waterproof speaker can sound muffled straight after a shower or a dunk in the pool. That’s usually just water sitting on the speaker membrane, not damage. Drying it properly brings the sound back and, more importantly, protects the charging port. Here’s the safe routine.
How Do You Dry a Waterproof Speaker Step by Step?
Turn it off, shake out trapped water with the grille facing down, wipe the outside dry, and let it air-dry in a warm, ventilated room. Wait until the charging port is completely dry before charging. The whole process takes a few minutes of effort plus a few hours of waiting.
- Turn the speaker off. This stops the driver vibrating water around.
- Shake gently, grille down, to release water from behind the grille.
- Wipe the outside with a soft, dry microfiber cloth.
- Tap it lightly against your palm, grille down, to clear remaining droplets.
- Stand it on a towel with the grille and port facing down or sideways.
- Air-dry for 2–3 hours, longer if it was fully submerged.
- Check the port is dry before charging.
Why Does My Waterproof Speaker Sound Muffled?
A film of water on the speaker membrane or trapped behind the grille dampens its vibration, which makes the sound quiet and muffled. It’s normal after water exposure and goes away once the water clears. Some speakers have a water-ejection feature that plays a low tone to push water out.
If the sound stays muffled or crackly after the speaker is fully dry, water may have got past a seal. Check our guide on whether it’s safe to use a Bluetooth speaker in the shower for the warning signs of water damage.
How Do You Dry the Charging Port?
Hold the speaker port-down and tap gently, then leave it to air-dry. You can touch a corner of a tissue to the port opening to wick out visible water, but don’t push anything inside. Many speakers warn when moisture is detected and block charging until the port is dry.
Wet ports are the main reason waterproof speakers fail, because charging current plus water causes corrosion. Close any port cover before using the speaker near water again.
What Should You Avoid When Drying a Speaker?
- ❌ Charging before the port is fully dry
- ❌ Hair dryers on hot settings, ovens, radiators or microwaves
- ❌ Rice, which doesn’t dry faster and can leave dust in openings
- ❌ Poking cotton swabs or pins into the grille or port
- ❌ Pressing buttons repeatedly while wet
What Should You Do After the Beach or Pool?
Rinse the speaker gently with fresh water (if it’s IPX7 or IP67) to wash off salt, chlorine and sand, which can corrode ports and damage seals. Then dry it using the steps above. Sand trapped in the grille can be cleared with a soft brush once dry.
Not sure your speaker can handle a rinse? Check its rating; our explainers on what IPX7 means and IPX4 vs IPX7 make it easy. Our article on how far Bluetooth reaches also explains why water near the speaker can cause dropouts. For speakers built for wet use, see the best Bluetooth speaker for the shower.
Frequently Asked Questions
How long does a waterproof speaker take to dry?
Usually two to three hours at room temperature after normal shower use, and longer, sometimes overnight, after full submersion. The charging port is the slowest part to dry, so always check it before charging.
Can I use a hair dryer to dry my speaker?
Only on a cool setting held well away, if at all. Hot air can warp plastic, damage the battery and weaken waterproof seals. Air-drying at room temperature is the safest method.
Why won’t my speaker charge after getting wet?
Many speakers detect moisture in the port and block charging to prevent damage. Let the port dry completely, which can take several hours, then try again. If it still won’t charge when dry, the port may be corroded.
Does putting a speaker in rice help?
No. Rice doesn’t dry electronics faster than open air and can leave starch dust in openings. Shake out water, wipe it, and let it air-dry in a warm, ventilated room instead.
Should I rinse my speaker after the pool or beach?
If it’s rated IPX7 or IP67, yes. A gentle rinse with fresh water removes salt, chlorine and sand that can corrode ports and damage seals. Dry it thoroughly afterward before charging.
The Bottom Line
Drying a waterproof speaker is simple: switch it off, shake out water grille-down, wipe it and air-dry for a few hours before charging. Avoid heat, rice and charging wet. For speakers built for the bathroom, see our best Bluetooth speaker for the shower guide.
