Acekool Portable Voice Amplifier with Wired Mic & Waistband, 15W Rechargeable Voice Amp with MP3 Player & U Disk for Teachers, Tour Guiders, Speakers, Seniors,Coaches and More

I was close to loosing my voice! I am a fourth grade teacher and could no longer sing and had a scratchy talking voice. This amplifier is AWESOME! It's affordable even on a teacher salary and so worth it. My students pay better attention, and really seem to be learning more readily. Several of my colleagues have purchased and love it. I can address a large crowd in the gym, or speak in a soft voice to a classroom. Amazing.

Maybe I should have spent a bit more and gotten a better quality amplifier. This one squealed if you got the actual amp lifer very close to the headset. I sent it back. Also the headphone cord TO the amplifier was too short and you couldn't really get it far enough away from you to keep it from screaming during use.

We have large parties (>25 adults) and the commotion during games is really huge. I bought this to play games at these parties. This one is loud enough for playing games such as bingo. I have not used the MP3 function, but I guess that will also be useful for other games like musical chairs.Taking one star off since the headset is not adjustable so it keeps slipping off.

I have used it to play mp3's on a sd card and it works great. The Mike is great also. Someone with a good voice could probably sing with their sd stored music. Yes, like ALL, you can get feed back if you get the mike too close to the speaker, but I have used it at full volume with the mike and had very little problem with feed back squealing

I have used this 5 days a week, outside for over a year. I give historic weapons demonstrations some times to hundreds of guests at a time with the wind blowing and airplanes flying over head. This voice amp works great. I have not used the USB or memory card function so I don't know how that works. I plug it in once a week, over night and it lasts all week. Only complaint is there is no way of knowing when it is fully charged. It's a bad day if I forget to bring this voice amp to work.

The only downside is that the microphone is a bit annoying to use. Other than that, great product. The battery lasts long and the sound quality is fairly good.

Works well, only down side is I needed a belt clip and not a strap

Works well for teaching classes and fitness class
