## Description

Jkoailiwi Upgraded Bluetooth Wireless Voice Amplifier, Black

Review: 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!
Review: 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.

*by A***D on 26 July 2025*

Charge the microphone before use. The charging cable is very short. Have used it once so far. It picks up other voices close by. The speaker can be held feet away from the microphone. The speaker can be turned down while the microphone is on so that there is no sound from it. It will work well for my theater group.
