### ⭐⭐⭐⭐⭐ Perfect for PE teacher!
*by S***A on September 24, 2023*

I’m a PE teacher and this headset is amazing! I’m able to project my voice in a large gym with a big echo and kids can hear me fine without me having to raise my voice and I’m able to run and play the activity of the day without ever having static or disruption. Best to hook the receiver to a good quality speaker!! But I’m very happy. I use rechargeable batteries for it. I teach all day, everyday and the batteries last a week. Just have a set pre-charged and you’re good to go.

### ⭐⭐⭐⭐⭐ Amazing Sound!
*by A***H on July 14, 2021*

This device sounds as good, if not better, than any of my stationary Audio-Technica or other Shure mics. Battery life isn't anything game-changing, but I did 2 gigs (about 6 hours) on a single battery, so that's not bad, and they're simple AA batteries, so cheap to get/replace. I haven't tested how far the range is, since I'm typically pretty close to the receiver, but I've never experienced even the slightest latency or sound-fidelity loss in distancing myself from the receiver. The headset is comfortable and has no issues with my rather clammy head after several hours of performing. Great product!

### ⭐⭐⭐⭐ Great product
*by D***D on July 21, 2024*

We bought this Shure headset to replace another brand that just wore out. When it arrived we put it to the test. It started cutting out. We contacted product support and they helped us fix the issue. All we needed to do was change the channels. Now it works great and my wife loves it.
