I used to give presentations to large and small classes, provide tours through our large factory and once even had 125 people on a tour of our town and I served as a guide. This little rechargeable voice amplifier is ideal to use in those circumstances and more.

If you are a lecturer, teacher or a tour guide this little device could save your voice. If you are ever in a situation where you have to speak to 20 or more people and act as a trainer or a tour guide you soon realize how hard it is to be heard in a larger room or outdoors. Within a short period of time your voice is strained and the people are always asking you to speak louder. With this device you can speak at low to normal voice levels and clearly be heard by everyone.

This little box features a rechargeable battery that allows you to use it for 16 hours. It comes with:

* The voice amplifier and speaker that weighs in at 9 ¾ ounces. It also has a belt clip on the back of the unit.
* An instruction manual
* An AC wall charger that is UL approved and it will operate on 100 to 240 VAC and 50/60 Hz. The charger cable is 45 inches long. It output is 10 VDC at 350 mA.
* A neck or a waist strap it is adjustable from 28 to roughly 56 inches in length.
* A lightweight headset that only weighs ¾ of an ounce that fits onto the back of your head and over your ears. The microphone is on a very adjustable goose neck adapter that allows you to easily adjust it to fit your needs. The cable to plug into the amplifier is 38 inches long.
* An auxiliary cable to allow you to plug in your mp3 player or smart phone to play your music. It is 41 inches long.

The amplifier has an on/off dial that also adjusts the volume output to suit your needs.

Usually one would expect that a voice can easily be heard in a 20 x 20 foot area, but that isn't necessarily so. Some voices simply don't carry, while background noise can all but drown out others under certain circumstances. Many, many times I've seen museum docents with these small amplifiers. The amplification is usually just enough to make one's voice heard over the din or throughout a small room.

The over-the-ear headset is very lightweight and quite comfortable, even with glasses. A small gooseneck allows the wearer to bring to microphone closer or further from the voice as needed. Of course there's there horrible squealing if you get it too close to the amplifier.

How does it work? It works quite well. It's definitely not a booming sound by any means, but the Ivation Digital Voice Amplifier does just that ... amplifies the voice. There are a couple of options for wear. You can either clip it to your belt or hang it from your neck, whichever is most comfortable or utile.

When I speak into the microphone, I'm not overwhelmed by the sound of my own voice nor do I hear any echoing. There's an audio-in if you care to play music in between those lectures or talks, a nice feature to add to the utility of the device. When I "practiced" in front of a family member, the experience was similar. No booming voice, but I could be readily heard within the confines of a small area.

Small area is they key phrase here. This is not an amplification system you could expect would work in an auditorium or large area. If you are working with small mobile groups of people or simply want to amplify your voice in small room you'll be just fine.

This is a small and portable PA that works best for small rooms or groups. The instructions that came with my review sample cite tour guides, educators and similar users. I want to add acoustic musicians. I am part of a duo with the other member who plays acoustic pianos and sings. Most of our gigs are in nursing homes and totally unplugged. Some rooms do require a mic for her vocals and this works with nearly every situation. For the totally unplugged performances this small speaker allows her to sing in a more natural voice without strain.

The sound quality is, frankly, best for the spoken word, but will suffice for the use I described above. The single sheet manual that comes with this claims 15 Watts output, but when driving the tiny speaker I am guessing you are getting closer to two to five watts. The instructions also claim 16 continuous hours between charges. I have never put it to that strenuous of a test, but can confirm that it easily goes for hours per day for at least a week.

I ran a test with an app called Sound Meter. Ambient room noise was 30 dB, and an acoustic piano at twenty feet raised it to 65 dB. Unmic'd vocals on top of that raised it to 72 dB and this speaker at about seventy-five percent gain brought it up a little past 80 dB. At max gain the speaker sounded a little tinny, do I did not measure it at that setting.

For what it is and does this is easily a five star product. However, there is room for improvement. First, the charger is similar to the obsolete ones that once charged old cell phones. A generic USB charger would be a vast improvement. Second, the mic connector would be more universal if it were 1/4 TRS instead of 3.5mm.
