The same thing happened to me. I dried them under the sun. Luckily, they seem to work fine unless it has open wiring then don't use it anymore. online
Hehe, seems like I do this once a year or so... Still using the headphones that came with my iPod Touch, they've been through the washer/dryer twice and are still working pretty well.
I've accidentally (and recently) washed 2 Bluetooth Headsets. My Motorola H690 went first, and it was destroyed. Still came on, but the little speaker.... shattered? Or something. It was unusable. Next was about 2 days ago and I washed my Plantronics Voyager 855, the whole stereo head set. And somehow... some way... is still freaking works just fine. I mean I don't know how it survived. When I found out they got washed I was like F*CK MY LAST SET!! I was so mad... but tested it, and it works just fine. Freakin weird.
