Review on KIMAFUN Fitness Wireless Microphone: Waterproof Headset Mic for Fitness Instructors, Spinning, Yoga, Smartphones, and Speakers - G100-1 by Todd Stovall

I am a fitness trainer and I have been teaching online since last March when the pandemic started. I teach every day and I sweat. The product information says it's waterproof, but my customers complain that the sound quality has dropped and sometimes they can't hear anything at all! Also, the battery drains very quickly and I have to recharge it after almost every use.
