Hi, I'd like to be able to listen to a podcast on my Iphone 10s while swimming. It seems like there are some waterproof headphones out there, but I don't know what the voiceover latency is like. I wish my airpods pro were waterproof! Even if I get the headphones, I would need a case and I'm not sure which one to get. I see that there are also waterproof mp3 playersbut I'm not sure about the accessibility of those either. Has anyone solved this problem?
