Shure SM31 vs PGA31: Which Microphone Is Best for Fitness Instructors?
Compare Shure SM31 vs PGA31 wireless headset mics for fitness instructors. Learn which microphone works best for indoor cycle, HIIT, yoga, and group fitness classes.

A wireless microphone for a Fitness Facility is a significant investment because if the microphone stops working, the show or classes stop! We recommend selecting the wireless microphone based on your planned usage at your fitness facility. This usage can be calculated by the number of hours the microphone will be used on any given day in the room you plan to use the system. More info HERE.
Each microphone model has been given an AV Now sweat rating that tells you how many hours of sweat exposure can be tolerated before the sweat starts to damage the microphone. Ask us via chat or email if you want to discuss sweat ratings. From our experience, it's best to explore backup options or heavy-duty microphones for facilities with several classes per day to ensure your fitness classes run seamlessly. AV Now offers Sweat Ratings on almost all of their microphones and can help you select the right microphone for your needs.
