Bluetooth Voice Amplifier Speaker Waterproof, Microphone Amplifier Wireless Portable Megaphone Loudspeaker 18W Output for Outdoor, Teachers, Coaches, Elderly, Tour Guide, Presentation and More (Black)

Not gonna lie, this product is quite impressive. Before purchasing the product I did not check its dimensions, but it looked powerful so I took it. It is actually quite small (maybe in lenght it's about the size of my hand). However, it produces a very powerful and clean sound. I love that the battery is rechargeble and that it can be used both with 3.5mm and Bluetooth. I'd say that it is quite straightforward to use, nothing that I haven't seen so far. The build is very robust and I do believe that it is waterproof (haven't tested it yet). When I fully charged the battery firstly it worked for about 12 hours? So yes, that is damn impressive and I strongly recommend this product.

Have not used it yet but tested it and seems ok. But it’s not as loud as I wanted it to be as my voice still seems small outdoors . I guess indoors will be sufficient. The Voice speaker headset not as comfortable as keeps moving whenever I move. Gentle movements works fine just no jarring or jumping movements. Will test again and update. Speaker is too heavy to clip on body so it has to be at least 1 meter away from body . Standing 3 meters away is still ok .

Useful and handy. Love it. Great use for hiking, just wear it around your body. Waterproof feature, great for outdoor use. Can be useful for karaoke and you can use a power bank for backup power. Great and useful tool.

What a terrific solution for our soccer program. We're indoors, in a large space with terrible acoustics, and masked so it's really hard for the kids to hear our instructions. We tried the voice amplifier and it works just terrific. Both of our coaches now wear them during instruction and it has saved their voices and helped the kids hear what is going on in class. I highly recommend this. They're a little tricky to learn to use, so give yourself time. Sometimes the bluetooth connection is lost and it takes a moment to reconnect. The mike is worn under the mask for the best amplification. My coaches are really picky and they love these. Easy to wear on the body even during exercise. Highly recommended.

The sound is great and it's super easy to use. The amplifier has a perfect sound quality and in addition that it is also a wireless makes this product amazing value of purchase. The volume is good and the battery lasts quite a long time. I connect very easily with my phone Bluetooth, used as a speaker to listen my favourite songs. All over working great so far.
