@dajbelshaw I see, I didn't even notice, but it seems like these are water-resistant. I've been using them for years, including for sport, and I haven't had any issues.

The only thing I'm missing is knowing the battery %. They have good battery life, but when it's running out it says an annoying "battery low" message every 30 seconds xD. I tried some apps a while ago and they didn't quite work... Maybe it's time to try again :).
