Voice Amplifier, Portable Rechargeable Handheld Mini Powerful Hands Free Wireless Voice Amplifier, 30W output with Detachable Wireless Microphone for Classroom, Conference, Training, Teachers, Guides

This is neither a wireless nor Bluetooth device yet the description represents it is. I got this because it stated it has a wireless microphone. It is a simple speaker with a mono 3.5mm jack, a volume knob, and an auxiliary jack. The microphone is WIRED. Amazon should really take this listing down as it is so egregiously misrepresenting the product. BUYER BEWARE OF THIS SELLER.

We needed this for a large group activity outside. It made it so much easier to conduct the meeting because everyone could hear. Good product. But if you are shorter than most people there can be sopme feedbackbecause the mic and the amp are too close together. Otherwise very useful.

Don't waste your time or money on this! It is junk. I thought if I paid more it would work better. Only used about 4 times and then went to charge it today and it will not charge. Looking for a quality product, it is not this one!

Not the loudest thing out there and does feedback sometimes, but I use it all the time!

This is a great product. The only issue I had with it at first was if the amplification box was too close to the headset or if the volume was too high it would squeal. Now I have it properly adjusted and it works great!
