Great headset but will need replaced after a year
I am a fitness coach and have used this headset for 6 years. It works good but like clockwork, it had to be replaced every single year, and i took extremely good care of this headset. Definitely buy the warranty

make sure you need a 4-pin XLR
Make sure you you dont need a 3 pin XLR receiver, only works with 4 pin XLR. These mics are great though.

It works!
Im a GX Instructor for about 10 years now and I've been looking for a nice mic for quite awhile now since covid hit - I just want to have my own instead. Ive purchased a couple mics here and there but none of them really 'works' BUT .. This one right here!!! FINALLY!!! The search is over! I am so happy with this and im glad I found it. It works really good, quality of the sound is good - my students can hear me Loud and Clear. The product is very light, it fits good around my neck. It's a little pricey ... but its ok. I used it the same night and im so very happy.

... no idea why these mics are considered to be perfect for fitness other than the rubber
I have absolutely no idea why these mics are considered to be perfect for fitness other than the rubber, and the slight modifications that they've done to prevent sweat and moisture from getting into the mouthpiece. These mics are horrible and, of course, we realized it outside of our return window. We are a boutique fitness studio and ordered the wireless set earlier in the year that came with one of these mics. Before we even opened our doors, we ordered two additional headsets for our additional instructors. HUGE MISTAKE. On our opening day, we had complaints that we sounded underwater and totally muffled. We checked our speakers, checked the settings on our mixer, and spent countless hours messing with the balance of everything. Still, nothing. We sounded awful. When playing the music alone in our class, it sounded perfect. When using the mic alone, there was a slight echo but nothing major...however, when we turned up that sound? Horrible. Finally, one of our instructors grabbed an old Shure WH20 from her bag and plugged it into our system. Underwater, echoing sound? Gone. Crisp vocals right over our music. So now we're stuck with three of these "fitness" mics that were absolutely awful, and I dropped another $300 on three WH20 headsets. Amazon won't let me return the SM31FH's, so I'm going to go ahead and send a little Email to Shure. Adding rubber to headsets is great and all, but when the quality of the mic itself is compromised? Totally not worth the buy.

Works surprisingly well for its price
This Mike sounded surprisingly well for its price point. The cardio pattern helps if you’re moving around a lot and you’re anywhere near your speakers. Some people said the cord was too short but they must have really long torsos. It worked fine for me with even some extra cable stashed in my pocket. Some reported it breaking in a critical area. I haven’t Owned it long enough to determine if it’s really fragile point. But I do tend to take extra care of my equipment, especially microphones. Only time will tell if the wiring goes intermittent at its connectors. Overall this was a good goodbye and I’d buy it again.
