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

Clear sound, excellent quality! The headset turned out to be too big so I wrapped a bandana (2) around it and now it works great. It came with a large port adapter, USB charging cables, cute little carrying cases, windshields, and other adapters. My only suggestion would be to add an indicator that tells you when the charge is low. I got caught a few times when he died in the middle of class. It needs to be charged regularly - the charge on the microphone doesn't last as long as on the handset.
