Your Bose QuietComfort Ultra Earbuds just took a swim, a drop in the pool, a rainstorm, or an accidental trip through the sink. The first hour matters most. Corrosion starts forming inside the electronics within minutes, and once that happens, recovery gets a lot harder.
Here’s the golden rule: do not charge them. Don’t plug in the case, don’t put the buds back in it, and don’t turn on Immersive Audio or anything else that draws power. Electricity and moisture inside the earbuds cause short circuits that can kill them fast. Get the water out first, then worry about testing.
Bose doesn’t officially rate the QuietComfort Ultra Earbuds for full submersion, so there’s no guarantee. But these steps give you the best shot at saving them. Work through them in order, and don’t rush the drying time.
Keep the Case Closed and Unplugged
The charging case is just as vulnerable as the buds. If it’s wet, leave the lid open, but don’t plug the USB-C cable in. The 5W input will push current into damp contacts and risk internal damage. Same goes for the Qi charging case if you have the separate accessory case; wireless charging through a wet surface can also cause problems.
If the earbuds were inside the case when it got wet, take them out immediately. The case will try to charge them as long as it has battery, and that’s exactly what you don’t want. Pull the buds out and set everything aside on a dry towel.
Shake Out Visible Water
Hold each earbud by the main body, not the stability band, with the nozzle facing down. Give it a few gentle shakes to let water drain from the speaker mesh and the microphone openings near the capacitive touch surface. Don’t fling them hard; you can knock internal components loose. Just enough to see droplets fall out.
For the case, open the lid fully and tilt it so the USB-C port faces down. A couple of sharp downward flicks help clear the port and the charging pin wells inside. The port is a known water trap, so make sure it’s dried thoroughly.
Blot Dry With a Soft, Lint-Free Cloth
Take a microfiber cloth and gently blot every surface you can reach: the earbud grilles, the two gold charging contacts on the bottom of each bud, the rubber ear tips, and the stability band. Don’t rub or push debris into the openings. Just absorb what you can see.
Inside the case, use a dry cotton swab to reach the charging pins and the corners around the lid hinge. If there’s visible moisture around the button on the back of the case (the one used for pairing and resets), blot that area carefully.
Air Dry for 48 Hours, No Rice, No Heat
Place the earbuds and the open case on a clean, dry surface in a room with good airflow. A windowsill or a desk near a fan works well. Do not use a hair dryer, an oven, or any direct heat, it can warp the plastic housing and damage the lithium-ion battery inside each bud. Rice is a myth too; it doesn’t absorb moisture from inside electronics any better than ambient air, and it can leave starch dust clogging the mesh.
Silica gel packets are your best friend here. If you have any from shoe boxes or electronics packaging, put them in a sealed container with the earbuds and case (lid open) for the full 48 hours. That helps pull moisture out from the internal cavity.
Check for Corrosion Before Powering On
After two days of drying, inspect the charging contacts on each earbud and the matching pins inside the case. Corrosion shows up as a greenish or whitish residue. If you see any, brush it gently with a dry, soft toothbrush. For stubborn spots, a cotton swab barely dampened with 90% isopropyl alcohol can help, but only after the buds are completely dry. Let the alcohol evaporate for a few minutes before proceeding.
If everything looks clean and dry, you’re ready to test.
Test Charging and Connectivity in Stages
Plug the case into power using a standard USB-C cable and watch the status light on the front. A steady amber light means the case is charging normally. If you see flickering, smell anything odd, or feel any heat from the case, unplug immediately. That signals internal damage.
If charging is stable after 10 minutes, place one earbud at a time into the case. After another 5 minutes, take them out and check if the Bose Music app (iOS 17+ or Android 13+) detects them. Open the case near your phone and look for the pairing prompt. If both buds show battery levels in the app, they’re alive.
Test audio with a short song, then try a voice memo or call to check the microphones. Even if everything works now, watch for uneven battery drain, muffled sound, or random disconnects over the next month. Those are signs of residual moisture damage.
Reset the Earbuds if They Won’t Pair
If the buds don’t show up in the Bose Music app or won’t connect, try a factory reset. With both earbuds in the case and the lid open, press and hold the button on the back of the case for 25 seconds. The status light will blink white twice, then slowly pulse blue, then turn off. Do that three full cycles. When the reset is done, the light will blink amber for 3 seconds then slowly pulse blue again. This often clears up Bluetooth pairing issues caused by electrical glitches after a wet event.
After the reset, try pairing again through the Bose Music app. If the buds still don’t respond, the internal battery or logic board may be beyond saving at this point.
