Voice Amplifier for Teachers-Bietrun, 20W 2000mAh Rechargeable(Working Time 20 Hrs), Microphone Headset and Speaker Set with FM Radio, Recording, USB+TF Card Play, for Meetings,Teaching, Coach

This thing is nuts -1. A digital radio!2. A sound amplifier!3. MP3 player!Generally good. About what you would expect from a voice amplifier, a bit tinny - but loud and clear if you are.MP3 player works, but only on one type of memory, and not both as the instructions say.Radio is aces.

Okay, first we've only had the system for about a week. Size is great. Volume level seems fine. The speaker is lightweight and easy to use. Sound quality could be a little better. For the price I think it will be a good product for our uses. I'll update this review after we've used it for a couple of months. It does have a one year warranty which is nice. Hopefully it will exceed the warranty by several years.

UPDATE - I’m concerned about being heard through my mask when we go back to school. So I charged this up and tested it wearing a mask. It works beautifully.I love this thing!I teach 7th grade history. My classes are only 45 minutes long, so every second is precious. This cuts down on the amount of time I spend redirecting at the beginning of each class. I’m soft spoke naturally so I don’t have to strain to be heard. I still have a voice by the end of the day and I’m no quite as exhausted.I can pre-record books on it using a flash drive. Then I can play them and monitor behavior or take attendance. I also don’t have to read the same book 6 times.My students hate it. They say I sound like I’m taking their order in a drive through. The voice recordings don’t sound that way. I think they don’t like the fact that I now drown out their side conversations.

I deliver presentations to groups of senior citizens. My voice needs to project to the back of whatever room I am in. This saves my voice and enables the audience to hear me so much better. I only gave 4 stars, because at the highest volume, it does give some feedback. I am sensitive to the weight of things around my neck, and this never bothers me. There are so many more expensive products out there that might have better sound quality, but for the money this meets my needs perfectly.

This headset and speaker set was just “okay” for me. I teach elementary vocal music and I have large class sizes so I need to be able to move around. There wasn’t a clip on the speaker so it was constantly moving around and I could keep it facing my class. The speaker was loud enough for my kids to hear but it wasn’t very crisp. It died completely (not holding a charge, wouldn’t turn on, etc) about 2.5-3 months after first use. I bought a different one that I am much happier with. All in all, not a bad set but not the best out there in this price range.

I ordered the KYQ01 & it arrived fast! I wanted to use it mostly to speak in front of a group of 40 folks outside & be heard by all - and discovered that I'll be using it for many many more things! It plays music off of tf card - what a cool thing to have around the house & outside. It even has an FM radio with an antenna. It's small size will come in very handy when I'm working in the garden. Thank you so much.

It doesn't look like much, but we found this little speaker great for boosting the sound for groups of up to 30 people (probably could do more) in an outdoor setting. With the shoulder strap, you could forget you are carrying it.

The volume was very good. My two classes (18 students each) could hear. However, the tinny sound interfered with their understanding.Caveat: COVID: I had to wear the mike under my mask - which it was not designed to do. So that didn't help. Still, it amplified everything (including my breathing).I think it would have worked better outside.Four months after I bought it, I received a follow-up email. The company refunded me my money!
