Works Wonders -- Well Worth Cost!
I belong to an organization of 2,500 retirees who teach classes to each other on a college campus. Between the hearing loss of most "students" and the large classrooms that hold 50-100 people, it is critical to have some sort of microphone. I tried one of the cheap versions where the headset is plugged into the amplifier which is worn at your waist. I returned it because it just didn't produce enough sound to make a difference. I read all the reviews on this one and figured I'd give it a try even though it costs more than double. Oh my goodness! People in the class were raving about it from the moment I plugged it in, and several came up afterwards to write down the name so they could go buy one. The wireless headset gives you complete freedom to walk around the room while the speaker sits on a table at the front. Everyone can hear everything all of the time! It is wonderful. I'm so glad I made the extra investment! Just be sure to fully charge both the headset and the speaker before your first use (I didn't charge the headset and it ran out after an hour; now both last for the full three hours of my class and then some). I highly recommend this product!

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.

Works great, good quality, good price, but user interface sucks.
This is a very nice and high quality unit with nice sound and the price is reasonable. Unfortunately the user interface sucks. There are too few control buttons, so they have multiple shared functions that are non-intuitive, so you really can't be sure what buttons to push for what, and there is no readout or indicator lights to give you any clue about what mode you are in or what volume you have selected. This is probably not that much of a problem for professional users who will use the unit every day and get used to controls. But for the occasional users, or older people (like me), the controls are very confusing.

Perfect for teaching
Perfect for teaching class with a mask and face shield. The students can hear me well, people in the hallway can hear me too๐คฃ Does not get very loud if it is not charged up, but on a full charge I can get through the whole school day.

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.

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!

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.

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.

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.
