I didn’t want a whole PA system since that is excessive and the booth space didn’t have much storage to hide a huge speaker. So I purchased this to save time and space! And it works like a charm. Had it on my hip, it was impressively loud, amplified my voice perfectly! Nobody had any issues hearing me that I know of, everybody was actually asking where I got it! It traveled with me to from FL to NV with no issues! I would recommend this to anyone looking to have a quick easy way to be heard in a large/semi-loud room or area! ### ⭐⭐⭐⭐⭐ Great for classrooms *by on Reviewed in the United States February 16, 2026* Excellent amplifier! Easy to set up and amplifies your voice significantly for use in a classroom environment ### ⭐⭐⭐⭐ Perfect for those who are still masking *by on Reviewed in the United States September 9, 2022* Due to age and health I still wear masks. It is hard for people to hear me when I speak and I get hoarse from trying to shout for extended periods. Enter this terrific headset mike and amplifier. It charges easily, can be hung around waist or neck, and has great sound amplification. My family was bowled over--they commented, "This is a 1000 times better than trying to make out what you say" or "I was doing the dishes with running water and I could hear you perfectly without straining or having to turn the water off." I can't comment on how long the battery lasts as I've only used up to 2 1/2 hours, so I'll add that later. It is a game changer for church, being in a car, going out into crowded venues anywhere as much as it is great even with 1 or 2 people inside. WONDERFUL product!
