I have had this small pair of portable Panasonic speakers for about 3 years now - beat the crap out of 'em on Mox and in the Pickets last year.
Recently, I had a energy drink puncture in a waterproof Arc'Teryx pack, fully submerging them. I poured the sticky mess out of the speakers, removed the batteries, then rinsed them thoroughly in a creek. Plenty of sand got in there, cuz I thought: this time, they are shot.
Just plugged 'em in with the recharged same batteries, still sounds great!
Other gear stories?
