This is a lifesaver & a voice saver!
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 Best Iโve ever owned!
I purchased this to give voice to my Cosplay. I have a 501st Legion approved First Order Stormtrooper. I was drawn to the wireless/Bluetooth capability and reviews regarding sound. Iโve tried many other less expensive versions and was always disappointed. Not this time! Although itโs a little thick and somewhat heavier, itโs the best, most durable wireless amp Iโve tried or seen! Amazing sound quality, capable of using memory cards for additional sound loops or wired microphone if desired. It is hands down worth the extra money, easy to use right out of the box, and has made a huge impact on my ability to interact with people while in costume. HIGHLY RECOMMENDED!

Light weight and reasonably priced.
I do school presentations and I never know if the school will have a proper microphone. This is my back-up. The battery will generally last all day, but I charge it over lunch if I am at the school all day. If the school has a dedicated P.A. system I use that answers it will sound much better. I've used it in gyms. It doesn't fill an entire gym, but usually the students are grouped together in one section. It claims it works for groups of 100 people and that sounds about right. I doubt it would sound good with musical instruments, but it works for voice.

You get what you pay for
This little thing does a fairly decent job, but the sound is really tinny and not really loud enough. I bought it for running choir rehearsals as the director during covid when we rehearsed in a room with a noisy exhaust fan exchanging the air so I could be heard over the fan. It does the job, but only just. Controls not super intuitive with no audible or tactile feedback when you press so unless/until you hold the buttons down you're not really sure it's doing anything.

A very good voice amplifier for the money. Great customer service.
We purchased this for a fitness instructor who teaches exercise classes. Overall the product works well, but when laying flat on your back doing exercises, the microphone / headset is pulled down by gravity and gets too close to the mouth. Otherwise it's been very good. In normal use we did not have this problem. Perhaps in a future model, the company could provide a more firm headset extension that works in any position. Problem and Resolution: Six months after my purchase, the microphone started cutting in and out during exercise sessions. I contacted the seller who provided incredible customer service. We emailed back and forth a few times to isolate the problem. After it was determined that there was a loose connection somewhere in the microphone headset, the company sent us out a new unit. The new one is working great. Thanks to Cindy for her pleasant email manner and overall great support.

Amazing, while it worked.
I thought this was a great product. It was easy to use and got the job done. I loved that it is small and can work anywhere. Unfortunately, after 3 months it stopped working. The amplifier would not take charge. It was not on sale when I purchased it and feel it was a waste. I tried reaching out for help and spent long amounts of time on the phone. I was told I was going to get sent a replacement and didn't. I was sent a charging box instead. I tried reaching out for help again and it was a waste of time.

Great Product Superb Customer Service Thanks ResponseBridge!!!
As a professional trainer and a lecturer, I was looking for a mini PA which is highly portable with professional looking (Not bulky). When I saw this product initially I got attracted for its outer appearance and professional look. However, I doubted about the loudness and sound quality. Iโve gone through the reviews and asked few questions from seller to clear my doubts. They responded me very quickly and clearly. I bought the product eventhough my shipping charges are higher than the product cost due to my urgency of need. I was really astonished with the quality of sound and loudness!! Highly portable. Mistakenly it has been dropped two times from my hand during the last 6 monthsโ time period. Thanks God. Its durable and well-built and nothing happened.

Solid purchase, but volume could be improved
The bluetooth tethering isn't very difficult to figure out. However, it does reset if the battery drains. Battery life is good, but it would be nice to either have a longer battery life or an easy way of putting in a battery to keep it going before recharging. Also would be nice to have two chargers since both headset and amplifier must be charged. This is very minor. That said, the maximum volume would be my only actual point of criticism. If you're standing somewhat near a busy street as an example, it would be good if generally the amplifier was louder than the ambient traffic noise. It's also very directional, so if the acoustics aren't the best where you are that's also something to consider. The fact that it is waterproof is dynamite! And being able to wear the amplifier is nice too. It's wireless, so no messing with cords. Overall very pleased with this amplifier.

Quite a impresive product
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.

Voice amplifier
Have not used it yet but tested it and seems ok. But itโs 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 .

Great Product
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.

The sound is great and it's super easy to use!!
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.

It works as described in the sales literature
The product is exactly what I was looking for. It projects sound in a room about 40 feet distance from the speaker with good clarity.
