Great sound, user friendly, charges quick
I use this voice amplifier in my classroom when teaching! It works well, is affordable, is user friendly, and connects to Bluetooth very easily. The sound quality and volume is also great. I like how simple it is to attach the mic to my shirt, and have even allowed students to read aloud with it on them! It adds engagement to my lessons as well as helps students to hear my voice over the noise of a busy classroom. It charges quickly and lasts all day for my instruction time (about 5 hours). I charge it each night to ensure I can use it the next day. I am happy with this product's quality, price, and user friendliness! 5 stars!

Affordable and reliable blue tooth Lapel Mic and Speaker.
Using the amplifier and clip for over a year now. It holds it's charge for a full dayof teaching. The clip still works after a year and the amplifier and speaker charge quickly. The sound quality and volume are fine for my large lab space classroom.

Good deal
Pretty good just wish we didn’t have to hold the mic so close to our mouth for it to work perfectly.

Good quality
The voice transmitter with lapel mic is a reliable and user-friendly device. The sound quality is clear and consistent, making it ideal for me to use while teaching fitness classes . The build quality feels solid, ensuring durability. However, the charging setup could be improved—there’s only one connector, which means you can only charge one component at a time. This small inconvenience aside, it’s a great product overall for anyone needing good sound and ease of use.

Poor sound quality and echo
At first I was impressed, but when someone else used it so I could listen, it sounded like a transistor radio, and when I tried it with my students, they all said they could hear a slight echo, even when I tried move closer or farther away from my mouth, and the speaker. It also cannot connect to other bluetooth speakers as I intended. I am saving it just in case, but bought a higher quality system from Best Buy.

Purchased for family member with Parkinson’s
I purchased this for a family member with Parkinson’s. It did a great job of amplifying her voice so that her hard of hearing spouse could hear her. Best with no background noise like a TV, multiple other people speaking. Long range enough that he could hear her from the kitchen/living room/etc.
