Love this mic! Lasts a couple years with continuous use!
Lauriela—August 31, 2025
Update! I just bought a second one. The design is slightly updated. Works like a charm. Hoping to get 2 more years out of it! I bought a different one recently, and that broke after 2 months (the strap broke the first week. Not this product! I'm coming here to give this item 5 stars. Will update with how long it lasts me this time around! This cute little mic lasted me 2 years of continuous teacher use before glitching in me. So sad. I loved it. Read more

The sound amplifiers are very good and easy to use . It was a bit strange not to be able to put it on the head but only around the neck, but I like it. They won't fall off like this. Thank you . Read more

The sound Is a good sound, it’s not super loud, but it was good enough for a small dance lesson. Good size but not heavy for a speaker. I got pink for her because of the color looks good. Read more

Voice Distortion
bennyv—April 4, 2025
Although relatively inexpensive, the quality of the amplification is lacking and causes your voice to sound somewhat distorted. Also, the microphone has to be placed exactly right to pick up your voice. Read more

Works wonderfully!
L. A. Tripp—October 10, 2025
I have a soft voice but periodically need to speak to large groups of people. This was inexpensive, so I thought I would give it a try. It works wonderfully! Now I don't have to yell to make myself heard. Read more
