Bose QuietComfort 45: Wired Audio works after getting wet but Bluetooth doesn’t

Thu, 22 Aug 2024 01:05:48 -0700

So basically, my mom has the QC45’s and she wears them as an EVS tech at the local ER and she dropped them when refilling a bucket so they got wet. We let them dry for a week and then plugged them in.

They light up to white twice then turn amber, but when you try to turn on the Bluetooth after charging, they don’t boot up.

Wired works but I have to do this weird thing where I plug it in to charge, turn it on and off a few times, then set it to off and unplug and then sound works fine.

I’m assuming it’s something to do with the connection to the battery if the sound is able to come thru but it needs a few weird power tricks to make it work. Is there anyway to replace the battery? Would it be worth it?

I feel bad because my mom got them as a gift and loved them for her work and she works really hard and these were the one expensive thing she let me dad get her.

Bose QuietComfort 45: Startup sequence doesn't work (very irregular)

Fri, 06 Mar 2026 09:35:23 -0700

When I try to start my headphones, the power indicator just flashes very briefly and dimly. The NC activates for a little bit, but the startup sound doesn't play, and the NC sometimes shuts down again. When I toggle the power to the off position, the light flashes more brightly, and the bluetooth connection and shutdown sounds are played before turning off.

If I hold down the power switch when starting, it sometimes makes the indicator light stay on, and very occasionally do the headphones boot up (maybe every 20 tries or so), but sometimes they stop working again immediately.

See this video for an example: https://www.youtube.com/watch?v=YzvnaKmj...

I opened them up and checked for anything off, but I can't see any corrosion or any loose cables/connectors.

Bose QuietComfort 45: Why my Bose QC45 is static on left side?

Mon, 22 Dec 2025 02:24:19 -0700

Why does my bose headphones have a popping sound/ static noise on the left side when it is powered on by Bluetooth?

I tried to use wired cable that both speaker were playing sound fine without powering on. I tried to power on with wired cable to heard a sound distorted sound on the left side speaker and right speaker was low volume.

Is this a power issue or hardware issue on my headphones? I tried resetting, and updating. I could not figure what’s wrong with my headphone.
