I was thinking about getting myself a pair of openrun pro 2s now that they're on sale but I'm pretty confused. Why is the IP-rating of the basic openrun model better (IP67) than the pro model (IP55)? The pros are about 50€ more expensive (and have the better sound from what I've heard), so why are they worse in that regard?

And why are headphones that people like to use while running outside not fitted with a rating that would allow running in the rain?

Or do I misunderstand the rating and IP55 is perfectly fine for sudden surprise-downpours? If anybody has any experience with the openrun pro 2s, kindly let me know!

Edit: I asked customer support. Basically sweat and light rain are fine despite the worse rating, but rain showers not so much. It's good to know some of you have made the experience that they can endure a bit more though.

Last Sunday I ran a 10 k race with the Shocks Openrun Pro. The earphones worked fine during the race and afterwards too.

However, When I tried charging those it keeps making a beep sound and vibrates. I dried those charging ports and points keeping it next to a fan. Also rubbed those with dry cloth.

I only had it for a 2 months so beyond the return period at Bestbuy but raised a claim with Shockz.

It is highly disappointing and now I don't have a backup. Is there anyone with similar experience? How did you get yours' to work?
