We use this for our party business for events, and it does very well. Projects really well too! Its lightweight and the voice quality is great too!

Great quality! I have a little voice and this helps ease up on voice strain during my class lessons and after school on duty. The charge holds well. I can use this for several days before needing charge. A few teacher friends have bought the same one after seeing mine.

This is a loud amplifier that works almost too well. I got it for the kids to play since some of them like to play theater and dance. It can get a little bit too loud but if that's what you're needing this is perfect for it. The sound is clear and it's not heavy at all

UPDATE 11/20/22 I had to send the other one back. It wasn't a mix issue after all. It was the part of the voice amplifier the head set went into. That was damaged which cause the issues with the headset. Now I forgot to mention last time I do alot of moving around d and bending. The clap for this voice amplifier doesn't stay on my pants sometimes and I have to watch to make sure I don't drop the thing off my hip. First comment: I love everything about this product. Its light weight and people can hear you down the hall! The only pull back is the mic headset. Mine stopped working after the first few I started to use it. I ordered back up headset I found Amazon, BUT it was $10 for two. Not bad but after buying a voice amplifier for $34, seems a little costly.

I lead a line dance class, and it was hard for dance instructions to be heard in the back of the room. This microphone and speaker have made it much easier. I can just clip it on my waistband and it stays in place. I only use it for about an hour a week, so I can't say for sure how long the battery lasts, but when I recharge it, it's done in about 5 minutes, so there was probably a lot of battery power left.

I have 4 of these. I bought 2 during COVID to use as I taught with a mask. Since I still wear a mask to teach, I continued using them and would charge each one as needed. Eventually, after about 5 years, they started losing their charge much more quickly (every couple of days instead of 3 or 4 days). I bought 2 brand new ones. The new ones use a USB-C charging cord, and they lose their charge after almost only one and a half days of teaching. All of a sudden, there's no charge without any warning. The only reason I would continue to buy this one is because it's pink.

This item has been great for a friend who speaks very softly after a stroke. It has allowed her to be part of a conversation again.

I bought this microphone for use on a bus with a group of elderly women. Our speaker was going to get on the bus and tell us what we would be seeing in Santa Claus Girls workshop. We thought it would be easier to do this while they were sitting and I knew they wouldn’t hear her. This worked very well, everyone heard her and the sound was clear and loud. Several previous reviewers commented on the screeching noise when the headphone came close to the unit so I tried to be careful but it did screech when I let the headphone drop down before I turned the unit off. I should have been more careful. I was very impressed by how well this worked for the low cost to buy it.
