SHIDU 30W Wireless Voice Amplifier with Lavalier Microphone, Bluetooth Voice Amplifier for Teachers, Portable Voice Amplifier with Bluetooth speaker with microphone for Classroom

I like that this voice amplifier is small, easy to wear, and makes my voice loud and clear for my whole class. The battery lasts all day and the Bluetooth range is solid, I can move around without losing connection. What I don’t like is the echo feature can be tricky to adjust. But overall, it really helps save my voice and does what it promises.

The sound of this player is excellent, it has loud sound, lasts quite a while charged, and is practical to take anywhere.

This was the worst wireless mic/speaker package I’ve ever tried. The spec sheet says it has 30W of power but the speaker is so light that there is no way it has that much battery or power. The microphone quality is terrible and makes you sound like a (very quiet) robot before delivering very unpleasant feedback. It also feels cheap and plastic-y. Overall a waste of money. I'm returning this immediately.

Despite it size, the sound is really good. It comes with a dual adapter to charge both at the same time. They connect to each other via bluetooth and function with ease. Both the mic and amplifier have a holding clip to be portable.

I wanted to use it for singing but it didn't work. Although it has an echo switch, the speaker voice is very "dry" and high pitched, maybe because too small in size.

I’m a line dance instructor and I haven’t used it on the floor yet but, my test run at home was GREAT! This is my third amplifier from this brand and I haven’t had any problems.

sound quality is amazing battery life is one of the best and Bluetooth easy to connect and voice quality is amazing and it’s really easy to use best for everything. Thank you so much.

Perfect sound quality and powerfull. A good divice for teachers indoor and outdoor
