They don't advertise the water resistance but I run with mine drenched in sweat and have never had an issue. I also put them through the washer and dryer (not in the case) and they work fine almost a year later. I wouldn't worry about carefully drying them..

I have not had the same success as you. I do a lot of running and I sweat a lot while running at full speed. Formerly, I would put my AirPods into their case as quickly as possible after a run to avoid losing them. The charging contacts ended up becoming corroded and I have cleaned them off multiple times to get the batteries to charge. The AirPods were not fully wet, they just had a sheen of sweat on them. Now I set them out to dry in the air for a while before putting them in the case. I suspect the new version will have the same problem. They are not really meant for vigorous exercise.

[Edited to answer your question to which I cannot reply because it is marked as dead:] The corrosion to which I was referring is clearly oxidation to my eye. It has a green color and requires scraping. Maybe our environments and usage are too different for comparison. I live in Central Florida, where it is quite hot and humid. According to my receipts, I bought these AirPods on April 5, 2017. I have been running with them almost every day since then.

Thats pretty interesting, you made me take a look at my charging contacts and they're still completely new looking.

I wonder why you experienced that and I didn't - I don't take particularly good care of my AirPods. The only thing I do occasionally is hit them with a paperclip to remove any earwax buildup because they get pretty gross after a few weeks of use.

I mean I'll go for runs in the rain, run in super humid weather, sleep with them in sometimes, and a host of other probably not good ideas and they just keep on working perfect after a year of this 'abuse'.

I would guess however that they weren't corroded in the traditional sense of the word, more likely just covered in a gross film?
