It's good for running, I tried to take the earbuds in the shower, but I don't submerge them in water of course, you can hear all the surroundings and the music, it kinda isn't comfortable when you wear a beanie over the open ear earbuds but, I bet it's like that with every open ear earbuds, it's hard to shake them off of your ears because I tried violently almost snapping my neck in the process (just kidding😄),overall the sound quality is good when it's quiet and when it's around 40-60% volume, you can hear the bass very well, but when it's above 70% the sound quality drops, but who listens to full volume? You would only damage your hearing, if you like listening loudly, then these probably arent for you the battery is also very well
