How do you COMPLETELY stop sweat from reaching your CI during workouts?

Hey everyone,👋 How do you guys prevent sweat from reaching your hearing device (or cochlear implant processor) while working out? Unfortunately, my old device got damaged because of sweat, and I can’t afford to be damaged again. I already tried using a sweatband, but it didn’t really help — sweat still finds its way to the device. So I’m wondering: What actually works? Are there specific methods, gear, or tricks that fully protect it? Would really appreciate any tips or personal experiences 🙏
