I am a part-time substitute teacher and wanted an amplifier like some teachers use. This is perfect to use when the class is getting loud and you need to get their attention or when you have a long lesson and don't want to have to project your voice for a long time. I like that it has two microphone options. The sound is very clear and perfect for the classroom setting.

I also really like the radio. It is fun to have a little radio that you can carry around. I was able to tune it into my favorite radio station and it is very clear. I have been taking it around the house with me while I am cleaning. I think I like this bonus feature as much or more than I like the amplifier.

I have been using this in my middle school classroom for a few months, as instructed by my ENT to save my voice. It has been fabulous! I love this and we have even named it! It can be heard by everyone in the room, and it never squaks or is fuzzy. Place the speaker somewhere away from where you stand, and be careful not to drop it. A friend got one and she put hers attached to her ceiling projector mount and also loves it. I am used to having the head set on now, and find it works best when I have a headband on, which I usually do for keeping my hair out of my face anyway (sorry guys). The speaker part is flexible and can be quickly turned away to have one-on-one conversations, allowing me to keep it on my head constantly. The charge will last most of the day but I tend to turn it off and charge it during a free period or lunch, just to be safe. The customer service at Winbridge directly (I went to their website) is amazing, they respond immediately with any questions. I highly recommend this product!

I purchased this WinBridge WB002 4 in 1 Rechargeable Voice Amplifier for my daughter's birthday party in the park. I needed something that's loud enough to catch a group of kids' attention so I could give them instructions on the party games.
The package contains WinBridge WB002 Voice Amplifier, wired microphone, shoulder strap, line-in cable, USB cable, and user manual. On the main WinBridge WB002 unit, there is a large screen to display current status in various modes and Mode/Play/Previous/Last/Record buttons below the display. On the side of the units, there are USB and 5V charger input. Lastly, there are Volume Control(Power)/AUX in/Memory card slot/Microphone In/Echo adjustment on top of the device. The voice amplifier has a built-in rechargeable lithium battery and the initial charge took about 4 hours.
PROs:
- Decent battery life. I have been using the voice amplifier for 6+ hours (ON and OFF) over the weekend and there was still battery inside when we left the park.
- Clear voice output. The output voice is quite loud. It's good enough to draw attention in a large area. The voice is quite clear and I didn't hear much distortion when I speak to the wired microphone.
- Additional features. When not using the unit to amplify voice, it also works as FM radio (extendable antenna is located on top of the unit), MP3 player (from music files on memory card or USB drive), Speaker (through Line-In port and external devices), and Recorder (to memory card or USB drive).
NOTE:
WinBridge WB002 also supports wireless headset as listed in the manual but it is a separate purchase (not included in package).

I am so happy I finally got one of these. I am a very soft talker, apparently from what people say. Not as bad as Seinfeld, but talking loud feels like yelling to me. So this should allow people to hear me without so much effort. Effective communication tool! yay! I teach classes and workshops, so this is perfect. It also helps to use it to practice for any kind of public speaking. love the color. It is vibrant and happy. It arrived very quickly. I was able to use it right away, right out of the boxes, although learning the features took longer, but the instructions are clear.i'm not sure what I would use the echo for, except scaring the hell out of my kids. It does say to fully charge it before using the first time, but it was nice that it had enough charge to try it right away. I am very happy with this purchase, as it seems to be high quality and will be very very useful!!
