SHIDU M808 Portable Voice Amplifier with Wired Mic IPX5 Waterproof 18W Loud Speaker 2500mAh Rechargeable Battery PA Systems Speaker Bluetooth Function for Teachers,Classroom, Meeting, Outdoors|Green

Very effective, clear sound and awesome battery backup. Best for teachers

It was damaged and old but good thing is I was able return it without any hassle.. Impressive Amazon service 👍

What I liked? Appearance. What I do not liked at all? Lasts only for 2 months. Although I have warranty, I cannot return it. Because, without it, how can I deliver lectures? Special note: When connected to computer or mobile, sound is at top whereas when used as a voice amplifier, sound throughput is much lesser. Will I buy it again? No. Rather I will buy better version from the same company.

Product is too much good But please manufacturing compact size like Ahuja

I recommend teachers not buy this product,it's waste of time, money & energy. Go for other best option.👍🙏

Realy this product very good and uee full

Literally no sound amplification. And amazon gives "Only Replacment" and no return. Pls don't even try....

Worth money. No issues even after few months of use.

This amplifier is nicer than some in that the sound is a bit more bottom-heavy and less tinny sounding than some, without adding too much weight to get there. There is no feedback, even when the mic is fairly close to the amp. The volume controls are not intuitive but are easy to use -- the reverse (lower volume) and forward (increase volume) buttons act as volume controls. You also have to hold down a button for three seconds to turn the unit on and off. Once you learn the controls, the unit is pretty easy to use, though you might have to look at the amp to do it. A rolling dial is definitely easier to use, but this isn't bad. Just different. Pretty happy with it.

Where should I begin? It took me some time and energy to figure out how this should work, and I still do not know how to adjust the volume. It's a mystery to me. Hey-- I'll admit to being a moron but I cannot see any kind of volume control at all. In fact, I can't see any kind of controls that I would expect to see. But I do hear, loud and clear, a voice tell me that it's "waiting for Bluetooth." What?? What is that about?? Why does this thing want to connect to something via Bluetooth???? Honestly, I can't figure it out. WHAT is it supposed to connect to? A computer? What? Lack of documentation really hurts this. They need to hire some native speakers to write their manuals and they need to put some effort into finding out what real customers might want to do with the product. I really think this deserves two and half stars, but I'll round it up this time. It does amplify your voice, I'll give it that.

I recently attended a Mother's Day function where I DJ the music but had no microphone to announce the different Mother and the events. This amplifier was loud enough for a crowd of about sixty people and easily connected to my phonee number is

Headset with amplifier works good and it is clear sounding. I wish though that the amplifier wasn’t so heavy or big it consistently slides down while I’m working out and conducting class.

We do drills sometimes for earthquakes and other things at the office, but we never liked the megaphones and things we had, this was a great choice, it sounds great and is easy to use and stores in a small space, we use it every time we have a drill to lead people out the building and give instructions, it's amazing.
