Hey! I was thinking about this only yesterday so I’m happy you found my old post! You'll be pleased to hear that I still use the shuffle almost daily but probably haven’t re-greased it for more than six months - so it’s been almost exactly a year and four months of almost daily immersion in chlorinated water for about 40 minutes (it’s clipped to my goggles, so it’s not constantly underwater, but I swim with my face down and come up for air…), then it’s rinsed off while I wear it in the shower. The trade off is that the buttons don’t work so well as I’ve rammed the %#*@ thing full of grease, but they do ok - the main problem is the play / pause button which doesn’t really work at all, but I just use the on / off switch as I only ever listen to books and I’m in the pool to swim, not fiddle with buttons, right?! This week I noticed the volume button was getting easier to click and told myself to remember to put some more grease in it but I forgot… To be honest I’m amazed it’s lasted this long, but I’m *very*...

I've been meaning to post an update here for ages... I did a relatively simple waterproofing job on the shuffle about four months ago. I use it to go swimming five times a week. I swim 1,000 metres each time and use the shuffle every time, both in the shower before and after the swim and - most importantly - during the swim! It's submerged fully for probably 2/3 of the time that I'm swimming and has so far lasted through roughly 100 swims, 100 kilometres in water and is still going strong. My simple method taken from here: injected with dielectric silicone grease through the headphone socket. I did this over a few days - I kept going back after a few hours and trying to force a bit more grease in to make sure all the air inside had been displaced. When grease started to ooze through the controls (which become rather stiff) I stopped. I then sealed the seam on the back of the shuffle with a layer of epoxy. Initially I was a bit paranoid about the switches on the side leaking, and the seal on the front round...
