Voice Amplifier Wireless for Teachers, 18W Personal PA System Ultra-Portable Megaphone with Wireless Microphone Headset, IPX5 Waterproof 5.0 Bluetooth Voice Amplifier Speaker - Indoor & Outdoor

Works well in water aerobics. Easy to put on. Easy to use. Everyone in the pool can hear her.

I bought two Wireless Voice Amplifiers but after a while one unit stopped working - the microphone would not connect via UHF. When I complained to the company they discussed the problem with me by email and then ended up sending a replacement. To make a long story short, in the end, with their help, I found that there was not a problem with the unit but that I had to press the button to switch to UHF a third time to get into the mode so the microphone would connect. I appreciated their patience in working with me and their willingness to send a replacement unit. In the end, I decided to keep the extra unit and pay them for it. The units work well and are very portable and easy to use plus this company has excellent customer service.

Speaker and mic work very well, clear sound and have had no issues using this in a large room. While the speaker battery will last as advertised, the mic battery is only good for about four hours.

This speaker dies at the end of each day, only using it for 2-3 hours, and the headset drains as well. I can't charge both over night and have them be ready for the next day of teacher. Also, speaker cuts out when I move to a certain spot in the room. The charging cord is extremely short and makes it very difficult to find a good spot to charge. So disappointed.

I returned the product for a replacement. I was disappointed. Completely satisfied at this point.

I'm a teacher. The amplifier is awesome, very clear and sufficient volume to talk over a class of high school students. The wireless headset mic (first of all isn't very comfortable), and only worked for 2 weeks. The wireless mic runs on UHF, not bluetooth. I'll keep the amp and just plug a regular microphone into it. But it's too expensive of a product for the wireless mic not to work.

I bought the 18w and the 25w, I use them singing on a moving train car. It works well. The 18w seems a bit warmer, but I prefer the volume knob on the 25 w. The push in, flat profile volume, in different spots, one for higher, one for lower, (18w) is difficult to get it to land just right while adjusting in performance. I use with the uhf wireless headphones, they also have volume control, but I suggest keep them on max. The digital readout of remaining charge is a plus. One oddity: it will discharge from 100 to @65% in one set, then it seems like I can do 2 or 3 more sets and it only drops to 45%. It didn't make it through a 6 set day without a recharge . I'm going to keep it, as my back- up. I seem to prefer the 25 w regardless of it's sound, it has lasted all day, I can add a touch of echo, and the convenience of the volume knob. Perfect unit would be: the EQ of the 18w, but with 25watts; the finish of the 18w casing( with belt clip), but with the volume& echo knobs of the 25 w; the digital readout of 18 but last as long as the 25.

I love how easy the unit is to operate. I am impressed how well it works. Everything is virtually intuitive. Love the verbal feedback when you turn on the machine and connect
