Review: Save your voice!! - This microphone did exactly what it needed to. I love how I don’t have to strain my voice during the day. The clip makes it easy so I don’t have to walk around with it in my hands or a headset. The microphone quality is nice and clear, as well as the speaker. There is a slight echo but it’s barely noticeable. I kept the speaker on my desk but if it was clipped onto my belt, it wouldn’t have been too heavy. The only thing I would change is the battery life of the receiver. It does seem to die a little faster than the speaker which can become inconvenient to charge midday. Otherwise, great product. Save your voice fellow educators!
Review: Great Headset - I've been looking for a headset for my mom who speaks very quiet, almost in a whisper. I figured I'd give this item a try since the reviews were pretty good. After charging the headset and showing her how to use it, I can say it works great for the money. It's nice to not have to strain my ears to hear her. You definitely have to keep it charged but it does a good job.

## Features

- 【Important Usage Notes】 As the microphone is an electronic device, placing it too close to the amplifier may cause echoing. To prevent this, we recommend turning the amplifier on only after setting the volume to the lowest level. Additionally, please avoid pointing the microphone directly toward the amplifier.
- 【Reduce Teaching Burden】Jkoailiwi 2025 innovative voice amplifier comes with a wireless receiver and lavalier microphone that seamlessly pair upon activation. This design offers a distinct advantage by eliminating the discomfort often associated with head-mounted microphones near the ear. It significantly reduces the teaching burden in class by a whopping 100%!
- 【Teacher Must Have】This portable microphone and speaker is an ideal and practical gift for educators who frequently address or instruct sizable audiences. Equipped with built-in Hi-Fi acoustic technology, it ensures crystal-clear audio projection, enabling classrooms with over 50 students to distinctly hear your voice, thereby providing effective protection for your throat.
- 【Long Battery Life】: The personal voice amplifier features a built-in 2200mAh battery, providing up to 20 hours of amplification on a full charge, with a recharge time of 3-5 hours. Additionally, the wireless microphone provides 5 hours of usage on a full charge in just one hour, and its wireless transmission distance is 20 meters. * Note: Physical obstacles and other wireless devices may reduce actual operational distance.
- 【Lightweight and Portable】 This mini voice amplifier weighs merely 200g and fits in the palm of your hand. Its compact size allows for effortless portability, enabling it to be comfortably worn on your waist without causing any discomfort or burden.

### ⭐ That radio screeching sound all day on this
*by J***. on November 3, 2025*

This thing is not designed for small settings of 200 ft² or less. My classroom is 15x15. And no matter where I'm at in the room the microphone just screeches that horrible sound. It sounds nice but they're realisticness of wearing it on your hip while walking with the wireless mic does not even get close
