18W Wireless Bluetooth Waterproof Voice Amplifier Portable Headset Microphone with Speaker Small Personal Microphone for Teachers, Outdoors

SAVE YOUR MONEY!This piece of crap was bought in September 2020. I used it few times when I got it but then it sat idle for a few months and when I pulled it out again in June 2021, the amp and bluetooth headset wouldn't pair.The warrantee was only good through March 2021, so I spent over a $100 for a piece of garbage

Bought this item for my Aquafit instructor to use so she wouldn't have to yell. Sound is good and battery charge lasts for a long time. The only downside is that the headset is not adjustable.

This is a great portable lightweight wireless voice amplifier that is easy to use and effective. The system comes with a two in one microphone that connects by bluetooth to the amplifier. The amplifier can significantly and clearly amplify voice; It's not quite as loud as a megaphone, but it’s pretty close. The controls are simple to use and easy to reach, and the bluetooth signal is very strong and reliable and can work across a large room. The amplifier has a large integrated rechargeable battery that can power the unit for several hours, and it can also be used as a battery bank to charge external devices like cell phones. The overall quality is very good, it’s built to last. This is an excellent portable voice amplifier that is exactly as described.

I am an elementary school music teacher who just began teaching in person again. I was SO concerned about losing my voice because I teach 7 back to back classes in the same day. I am naturally a loud person but projecting through two masks and over students talking and playing instruments just wasn’t something I saw being possible. This microphone was a LIFE SAVER. If you are a teacher, instructor or facilitator of any kind I highly recommend this microphone. The only (minor) flaw is that the speaker/receiver part is larger and heavier than I expected and when I tried to wear it on my waist line, my pants would sag. I just place it at the front of my classroom and I am ready to go!

Taught 2 water fitness classes with this and worked perfectly!

I'm a yoga teacher who teaches classes outdoors and the microphone cuts in and out. I basically have to have the mouthpiece in my mouth consistently for it to work. The speaker crackles from time to time as well. I tried using it a few different times and feel like I can give it an honest review. I'm returning it and getting a different type.

This portable amplifier is amazing! It’s just what I was looking for and it exceeded my expectations! I love how easy and simple it was to get together and use. Also, when I used it I love how I didn’t need to raise the volume of the speaker as much because it came out really loud already. Plus, I don’t have to worry about leaving it on my desk next to liquids because it is waterproof! My kids are able to understand me without the sound coming out like an echo! I love using this!

I'm a middle school Music teacher and I use this for multiple classes. This is particularly good for larger classrooms or noisier environments -- the speaker is wireless, so I put it in the back or side of the room so everyone can hear me more clearly.I have to teach with a mask on, so I purchased a "stage manager's mask" that has a slit in the side, and I feed the mic into it so it can pick me up more clearly. That is much better than having the mic outside my mask, where it would not pick up as clearly.It's great for a Piano Lab, a Band class, or even a Chorus room so you don't have to shout over the noise and through the mask.The wireless connection is quick when powering it on. Speaker battery lasts a full school day. The mic doesn't quite last an equal amount of time, though, hence my 4-star rating.

Battery charge is too short. I use the amplifier because I have sustained nerve damage to my Larynx and vocal cord. I cannot be heard if my voice is not amplified. I found that this amplifier does not last long enough. Additionally, the speaker head set has the same problem - Battery charge is not nearly good enough! I would appreciate suggestions for this issue. Thanks!

with its size it has really great sound amplification and easy to cary

WOW! My classroom teaching experience has changed for the better. I turn on the speaker and set it at the front of my room while I walk around the 30+ students and EVERYONE CAN HEAR ME with the wireless microphone!!! I don't have to use my "teacher voice" anymore and I can save my precious vocal cords for yelling at my husband when I get home. Every teacher has to get this for their classroom. I'm much calmer, the tone of my voice is more pleasant, and the students don't have to stress trying to hear me over the dehumidifier, fan, and ancient HVAC system. I only wish I had bought this sooner! I've told every teacher on my campus about it and they're getting one, too.

Product delivered sooner than expected. I have been using this is in my classroom to help amplify my voice and it does such an amazing job. The sound quality is great. My students can hear me clearly no matter where I am in the room. The battery has lasted two school days long without being charged yet. I also use the Bluetooth function to play calming music. I am pretty clumsy and have already dropped this twice and it is still working. Although the product feels lightweight, it is surprisingly durable. This has been a game changer in my classroom! If you are anyone who needs your voice to be heard in a large room for instructional/ informative purposes, this is the product for you!

This is the second unit I have purchased. I was hoping to pair both speakers to the one headset, but cannot.This unit doesn’t indicate when it is paired to the headset (the other unit tells you), and this unit has a delay in time when switching the mic on after it was switched off. Need to wait about 5secs before talking. It also drops in and out often. I use it for teaching Pilates indoors.
