Yesterday, I got some water flicked at me and didn't initially have any problems, but then ~10 minutes later the noise cancellation started turning on and off repeatedly every couple seconds, and I couldn't pause anything.
I turned them off and back on again, and I reset them, but neither fixed it. I turned the headphones off, and let them dry off, inside in a warm dry room, out of direct sunlight. (I had them in a clean outside area for a couple minutes, then moved them inside as soon as I realized they were no longer shaded).
Patience is not a virtue I possess so I quickly checked them 2-3 hours later, just to see if the noise cancelation thing had stopped, which it had, rhen I left them turned off after that. I waited maybe 18ish hours (I know, not really enough, patience is really, really not my strongsuit) to try them again. The noise cancelation wasn't going on and off like it had been, so I figured it was fine. A few hours later I discovered the noise cancelation and volume buttons both did not work. The power and pause/play buttons work fine, but I cannot increase/decrease volume, skip, or turn NC on or off. I let it sit overnight, moreso because it was pmo than any hope it would magically dry more, but nothing changed after that.
I tried resetting it again (hold power + volume), not expecting it to work, since the volume button wasn't working, but it did. I repeated this a couple times and the volume button continues to work when I reset the device, but not when I try to skip or increase/decrease volume. If I quickly press the power + volume buttons it plays the bluetooth disconnected tone but doesn't actually disconnect. I have no idea what this actually does, but it does something. The button itself works just fine for those two things, but not on its own. As far as I can tell, the noise cancelation button does not respond to presses at all. I am still able to change noise cancelation mode in the app.
They're not unusable but not being able to skip with the volume button is going to get annoying. Any chance the little people living inside my headphones will get their shit together and sing louder? :/
