Reading this with interest!
Last weekend my wife washed my SE535's (in pocket of workout clothes) she brought me a very soggy pouch containing with my custom moulds and my very wet Se535's and my iphone accessory cable and said quite nicely that "these probably won't work again"...
Although I silently agreed with her I thought i'd give them a go, and there was life, not a lot but it was definitely there.
I took off the cable and then left them tip up for any vapour to escape for a day in a very sunny window to gently heat them through.There was more sound, quiet through the whole range and definitely missing a whole lot of treble and mid but they seemed to be recovering.
In the meantime I'm looking for new ones and wondering how to convince herself and me that a second pair won't go the same way as the first!
I thought i'd leave them for a few more days, swapped out the cables back to the (mostly unused) originals as I thought the music controller may have been damaged and didn't want to write them off too quickly for that reason.
They were back!!! They were like new, I gave them a run in overnight at a reasonably high volume just to loosen them up again and the morning after they were pretty much back to normal.
I then swapped the cables back out again to the music controller and again it all worked!
So if you've washed them maybe it's worth just sticking with them, put them somewhere dry and warm (or in a bag of rice to draw out the moisture) and don't expect immediate results. I may just have been very lucky but they were in that washing machine for nearly two hours so they must be built like tanks!
I've since spoken to Shure and they advise that should I have any more issues they can do a service exchange for a reduced price on new (as being in a washing machine is not a warranty issue!), but that if they are working then why spend the money!
