Voice Amplifier with Wireless Headset Mic - 18W 4400mAh Rechargeable Mini Pa System, Bluetooth 4.2, Waterproof IPX5 Portable Speaker for Teacher, Outdoors

The unit is small and it works really great. I hold safety meetings inside our production shop with approximately 60 employees and they all are able to hear me loud and clear. Easy to use and it holds the charge pretty good. So far everything is working as it should.

Currently I teach future special education teachers at a university. With having many students in my classroom, I can find it challenging to be heard over them when we are having group discussions. Since, I started using this voice amplifier I no longer have this issue. My voice is now loud and clear so my students can here me. Plus I never lose my voice trying to talk over the students, the amplifier helps with this issue. I love that I can teach all day and not have to worry about the battery life of this amplifier. My students performance has increased and the background noise has been decreased. This tool is needed by every teacher. It has been a game changer for the way I teach. I love that this voice amplifier is lightweight and portable. Thank you so much, I am one happy teacher!

It works, seems durable. I wouldn't buy it again, if anything happens to this one. I'll probably try my luck with a different one.I bought this as a replacement to one that was wired that I dropped & broke. It seems alot more durable (at the additional expense of double what I paid for the previous one.)CONS: The mic. and speaker have to be charged separately, and charged after about 2 uses (I use it for about 1.5 hour long each time), and only one coord/ plug is provided. Also if you just leave it on, i.e. forget to turn our off, even if you are not using it, the battery drains very quickly. PRO: It has a counter to tell you how charged the battery is. First the speaker part only. The headset charges very quickly.CON: The speaker emits a pretty loud hissing/static noise, but out doesn't seem to affect the video recording of my voice output. I can hear it with my ears, wherever the speaker is located.It has rubber "doors" where you'll find the plug ins and stuff inside, kind of a pain to plug the charger cord into. Also the charger cord can't be more than 9-12" long basically useless, if you want to charge while using, unless you plan on leaving the unit on the floor, and also charging it on the floor.

Good - I love the sound quality for my classroom. This amplifier is great.Bad - I like to place the amplifier on my desk and walk around the classroom. The mic loses connection when I turn my head.I will be trading the wireless model for a wired model. Also, a wired microphone is required to record your lessons.

This worked great and out performed some other folks at our event with 'better' 30w units. I actually had compliments from our participants on how clear my delivery was over this. Took a few mins to understand the multifunction buttons. But this is a very quality and versatile unit for the price!

We tested it, and I sounded functionally the same with or without it. Maybe a speck of a difference, but not nearly what I’d expect from a microphone especially at this price.Don’t waste your time.Winbridge S388 was Much Much louder, but after much effort the seller confirmed the machine needs to be paired every time it’s turned on! No way! Great volume, but I don’t recommend that either (not reasonable to constantly pair.)

I am a riding instructor that has a difficult time sitting and giving a lesson so I needed something that would be mobile with me. The speaker worked beautifully for the first couple lessons and I thought what a wonderful thing, then after fully charging it for the next day of lessons the headset would not connect to the speaker and completely stopped working. I am so incredibly disappointed in this product - I understand it is only $100 but it should work longer than 1 day of use. I would like a replacement or my money back but never received either.

I used this product in my class especially when I am doing math exploratory and hands on activities because students loved it when they are engaged. Before buying this, I struggled a lot on how to deliver clear instructions to them especially when our activity is set in an open space like outside the school building. This helped me a lot to deliver clear expectations of the activity since the product can amazingly amplify my voice and has better audio quality compared to my previous amplifier. It has a long battery life as well. I charged it at night and I can use it the entire day in class.
