I made an exit (1 hour trail running) with a little rain early for 20 minutes and 20 mist and headphones still sound good.
Regarding comfort, I have no particular worries knowing that I do not driven into the ear because I want to hear my steps when I run.
I add just a plaster on my neck to block the son headphones to avoid pulling on the ears.
I think I have bought the right product and I thank all the people who comment on the products and guides buyers.
If a problem with my product, I will publish my comments for everyone to benefit.
