Review: 10/10 Voice Saver - If you are trying to decide between this voice amplifier vs one of the cheaper, wired ones, I would encourage you to go for this one! I have tried both and experienced a lot of feedback issues with the wired amplifiers but have not experienced anything like that with this one. My voice becomes clear to the back of the room even when speaking at a very low volume. The battery life problem hasn’t really been an issue for me and I really appreciate the convenience of them providing a dual USB-C chargers so you can charge the speaker and headset at once. I coach an outdoor color guard team so I am constantly competing with instrument sounds outside and have come to rely on this speaker to save my voice. I also love that I can connect my phone via Bluetooth but honestly sometimes just end up holding my phone to the microphone because I get lazy. This speaker connects easily and transmits clearly so I would say it works very well. I am satisfied and will most likely be getting another set to keep in my classroom.
Review: Professional Grade and Reliable - I am absolutely thrilled with this wireless microphone! The sound quality is crystal clear and professional-grade, and the wireless range is incredibly reliable. I've used it in the classroom and in the cafeteria with 100 students and they can still clearly hear me. The battery life is long-lasting, and the charging process is quick and easy. The microphone is also very comfortable to wear, and the design is sleek and stylish. Overall, I'm so impressed with this wireless microphone and would highly recommend it to anyone looking for a high-quality, hassle-free audio solution!

### ⭐⭐⭐⭐ Teacher Tech Must Have :]
*by G***O on November 14, 2024*

This review is for the M801 Voice Amplifier in the Black Color. The item arrived nicely packaged with the amplifier box, headset microphone, adjustable fabric strap, and charging cables. Positives: It charges quickly. It makes noises to let user know when its on. The light on the headset is green when it is turned on as well. Cons: I wish the headset that rests on my head could be adjustable. Sometimes it slides depending on my hairstyle. I have used it in my classroom everyday for many activities. It helps students sitting further away from me during read aloud stories. I use it while students are cleaning up to give directions. I even use it during dismissal time to call out children's names as their parents arrive. It is a great addition to your classroom and it saves your voice!!
