DuaFire Black Voice Amplifier Portable Microphone Headset with Waistband for Classroom Teachers, Speakers, Yoga Instructors, Gym Directors, Coaches, Presentations, Seniors and Tour Guides

I ordered this product because it was recommended on a music teacher page on Facebook! That day I ordered mine, so many other teachers ordered theirs!!! It was such a huge hit, that one of the teachers I work with borrowed immune, I ordered 2 for the PE teacher I work with, and at my other school, another music teacher ordered one!!! Batteries aren’t even needed!!! You just plug it in to charge, and it lasts days! The amplifier is loud enough that double classes in the gym can hear the PE teacher. The downside is I also use mine while she uses hers so we’re competing against each other to be heard. (I’m a music teacher who teaches on the stage.) It’s hard to find an affordable product that works perfectly. But this is it!!!! Best $26 I ever spent!!!!

This voice amplifier is loud. The volume control allows you to set it where you want it, so it doesn't always have to be full volume. Using the microphone headset is surprisingly comfortable. I've also plugged up my phone with the provided cable to amplify music playing.The battery holds a charge for an unknown amount of time. We have used the voice amplifier for hours and still not ran at dead. We then just charge it back up to ensure never having a dead battery.I like that this voice amplifier is simple enough to let the kids use and play with it. This is great for them to sing and be the outgoing kids that they are. If anything ever changes with this voice amplifier then I will update this review.

I got this voice amplifier for speeches and presentations delivered in a larger space. My voice does not amplify well so instead of straining my voice, I decided to try this device out. The box came with a voice amplifier, microphone, battery charger, MP3 Audio cable, and an adjustable waist belt. The amplifier was a little bigger and heavier than I liked but overall, I found this product to be a good purchase. The volumn is adjustable so you make it quite loud if needed. Just be careful about holding the amplifier too close to the microphone because it will make a horrible noise. Also, note that the microphone band is not meant to go over your head like a headphone but behind your head so that it's not as visible to your audience. I initially tried it on as a headband and found it uncomfortable so it's not meant to be worn that way.

I bought this to use with a singing/dancing group. As an instructor, it's saved my voice these last couple of weeks! I don't have to shout over the music to be heard. I am able to give dance instructions to my students that can be heard above the volume of the music. The children have taken turns using the mic during rehearsals for their solo parts. The clip holds well on a belt or waistband on jeans and works for both children and adults. The headset is not adjustable, but you can move the mouthpiece to get it in the right place for the best sound. The mouthpiece does need to be right in front of your mouth to be heard, but that hasn't been an issue. I have not had any problems with feedback - just keep the headset and amplifier box from getting too close or it will squeal. It's been great for rehearsals in a smaller space. It would not have sufficient amplification for an auditorium, but it works great in our smaller practice space (20'x50'). I have used it for several hours already and still have not had to charge it.Why 3 stars?...6 months in, it no longer works. The connector where the ear piece connects has issues and I cannot get amplification without holding the earpiece in place.

We are using this for a group that meets weekly in a portion of a much larger open space. Outside noises and especially the HVAC noise in the summer make hearing a challenge. The device is easy to wear & the sound can be adjusted to just the right degree of loudness. Unfortunately the amplifier doesn’t fix the phenomenon of guest speakers who think they “can talk loud enough” without it 😀 Not true as the normal modulations of our voices when we speak for a period of time benefit from volume enhancement so listeners are concentrating on the speakers message rather than if they are hearing the words correctly.

About a week ago I was told by my ENT that I have nodules on my vocal chords. They are too small for surgery and I need to shrink them naturally by letting my voice rest. Unfortunately, I am a teacher and this is nearly impossible so I looked into some tips to deal with this issue.Many people said to get a headset microphone for while in teaching. This headset got great reviews so I ordered it. It came earlier then expected and thank gooodness because my voice has felt really tired and sore...but! The microphone was defective. I tried everything and it does not work. Not a single sound. Very frustrating. I had to return it and now have to decide whether I want to order another one or go with another company.

I recieved this today I am pretty pleased with the product. I bought this to use under my 501st legion tie pilot costume. Children can not hear me when I am in full costume. I am hoping this cures that issue. I ran a test today and it seems to do the job. The box doesn't sound great when I speak down the boom Mic but may be I need to have a play around with it more. Overall pretty pleased with the purchase and for what you recieve for the price it is perfect.

I'm a teacher who is suffering with nodules on my vocal cords, and I purchased the product at the end of the previous school year to ease the strain on my voice. It worked very well last May and June, and did help my vocal cords. This year, however, there is a lot of static, and I have to constantly adjust the microphone jack. BUT I contacted the seller who provided a replacement at no cost and it is working great!
