ZOWEETEKOriginal Voice Amplifier for Teachers with 2 Microphones, Wireless Voice Amplifier Microphone Headset, Portable Speaker Megaphone for Classroom, Training, Teaching, Yoga, Meeting, Speech

This saved my voice when I was a teacher, and I can't imagine teaching without it! I love that it comes with two mics - one is wireless, and one is wired. I could use the wired one and pass around the wireless one for my students to use (they were wearing masks so it was hard to hear them speak). Used it for two years and had no problems with it! Battery life was great.

I bought my first voice amplifier during covid, when I had to teach with a mask. Before that, I had recurring laryngitis caused by vocal cord fatigue- when you're trying to project your voice all day to a class of 30+ kids! This little device has been a life saver! This is the second one I buy (the first one lasted 3 years). I don't use it for every class but I'll keep teaching with it until I retire. Great buy! I love the blue tooth microphone.

What I like about this unit is that it has a wireless microphone. It comes with two headsets, one has a wire and one is wireless. The speaker unit last for a longer amount of time than my wireless headset. It states that it should work for about 2.5 hours total. This is not enough time in one of my teacher workdays. What I do is shut it off and only turn on the power to the headset and speaker when I absolutely need to speak into it. After six months of classes, it started to just cut out on me like it was dead, but the power was on. I would switch it off and then back on, and it would begin to work. Gradually, as I continue to use it the amount of time that it would last is getting shorter and shorter. I decided to invest and buy a second unit. Now I am rotating my two units so that I can try and have enough battery to get through the school day using the microphone. What I like about this is, I can speak in a very calm and normal speaking tone of voice and yet my volume is loud enough for everyone in the classroom to hear me even when everyone is talking and the volume is high in the room. That way they can all hear me so that the students stop talking and be quiet to listen. The quality of sound from the speaker is better than another brand that I tried. I leave the speaker on a shelf rather than wear it on my body as I don’t like it clipped to me.

I love how easy this is to use. Comes with a wired head set as well as a blue tooth headset. It also comes with it's own charger. I use it in a room of about 30 people and have no issues. I used it in a room with a cathedral ceiling and about 100 people and some people struggled to hear. I love this product and recommend to all who need a boost.

La carga no dura mucho, ya el fabricante dice dura 8 horas, pero no máximo de duración 6 horas continuas, a veces falla la conexión con auriculares portatil

I purchased this because I damaged my vocal cords trying to teach and keep my students engaged (and manage behaviors).The damage to my larynx was so severe I could hardly talk above a whisper.This has helped my voice heal by making it possible to project my voice without strain.Easy to use. Loud but not too loud. Not feedback issues so far.

Updated Nov. 17, 2021I changing my review from two stars to one. The day after I wrote my review, the strap broke. It was glued not stitched. What made me update the review is that the unit is no longer working. It is not charging- even using a different charger made for the unit. I wouldn’t purchase this at all.I purchased this to use in my second grade classroom. Between my face mask and the plexiglass partitions, students hearing me in class was difficult. My colleague loved this unit so I bought one. I use it daily in a second grade classroom.Pros: when it works, there is good volume control and students can hear me. It has a removable clip and a nylon strap that can clip onto the unit so you can wear it. The charger charges both the Bluetooth headset and amplifier on one plug. There are two headsets-wired and Bluetooth. Both have a flexible mic that holds its position well. It has pretty straight forward directions to use. The price point is affordable.Cons: Not reliable at all! The unit comes with two different headsets- a Bluetooth one and a wired one. Neither one is very comfortable and both have a 90 degree turn near the ear that gets caught in my hair constantly.The amplifier and the Bluetooth headset do not always connect. Sometimes it stays connected for about an hour, sometimes longer. Most of the time it doesn’t stay connected or won’t even connect. I have given up on using Bluetooth because it was frustrating and not reliable.I have now been using the wired headset and wearing the amplifier at my waist. It is a bit more in consistent in working. Often there is a long pause of 3-5 seconds when I first turn on the unit and I can use it to amplify my voice. Annoying when you turn the unit on and off frequently. There is also the feedback squeal. The amplifier is very sensitive and often will squeal if the mic is even facing in the general direction of the speaker. I have to make sure the mic is up close to my nose so when I bend my head it doesn’t cause feedback.I am using this amplifier since I did purchase it and it is past the return date. I would definitely not purchase it if I had to do it over again.

This has saved my voice this year! Works well. The wireless headset allows me to leave the speaker at the front of the room but then walk around as I give notes. If I am facing the board writing a problem my voice can still project out to the class. Overall wish I had gotten one sooner!
