Bought this for my wife to use in the classroom. We thought it would help her voice carry in the larger rooms, but the sound quality of this was terrible.

Microphone quality is not great, it has an echo that students found hard to ignore. Noise level is reasonable, works if I put the speaker across the classroom, so perfect for classroom use. Weight is perfect, almost feather like. Easy to use, but not easy to determine how much battery level it has. I charged the microphone fully to ensure it would be ready for the next day, but it stopped working after 2 hours (low battery). I like that it clips on shirt with no feedback. Keep in mind it doesn't come with charger block (only cord). I will be returning.

my husband a pastor and Bible teacher has a soft voice. My daughter said buy him this microphone with a little speaker and it will help him. We tested it out today and it did a great job.

Purchased 4 of these for a company meeting. They worked great. The speaker was placed in the back of the room and carried the sounds just right. We put the volume at 7. We also used at a restaurant for a company Award Dinner. Versatile and easy to use. I recommend this product.

Works well but the audio is a tad distorted at higher volume.

This upgraded voice amplifier works well in my classroom. I am a first grade teacher, sometimes I have to raise my voice a bit during the class & I usually lost my voice by the end of the day. With this voice amplifier, it saves my voice. It’s easy to connect the mic to the speaker. The sound is good, they can hear me fine & the volume can be easily adjusted.

Sound was bad everytime you take not only is it slightly delayed it had a echo. No feedback when mic is close but if sound quality is bad doesnt make this a good bad especially when it says it's the upgraded version.
