Voice Booster VoiceBooster Voice Amplifier 10watts Black MR1506 (Aker) by TK Products, Portable, for Teachers, Coaches, Tour Guides, Presentations, Costumes, Etc.

This amp arrived quickly, so I've got no complaints on the shipping time. The price is also VERY reasonable for what you're getting. Believe me, I know, as I've priced these other places, & this is about average or maybe even a little cheaper than most places I've looked. I have to say, this is by far the BEST Voice Amp I've ever had! It's compact, lightweight, & LOUD! I'm a member of the 501st, & am using this Amp on my Darth Vader costume. For those who may not be in the know, the 501st is the Premiere costuming group for Star Wars villains. Actually, I use 2 of these amps on my costume, & IT IS LOUD! Did I say that this is LOUD? Ok, I think you get the picture. These amps are used in conjunction with a special voice changer, to give me the appropriate "DARK LORD OF THE SITH" voice. It sounds AWESOME, & I get TONS of compliments by screaming Fans at the Conventions I attend, after they realize I can talk! People have no trouble understanding me in the noisy & crowded halls at the typical Comic Book conventions. I should note that this amp is currently being used by a LARGE # of 501st members for different costumes, including Darth Vader, Stormtroopers, Clone Troopers, etc...So if you're in the market for a really good, compact, light weight, & LOUD voice amp, BUY WITH CONFIDENCE!

I purchased the Aker MR1506 to amplify my speaking voice, which has been decreasing in volume and clarity due to ALS. It works well to provide added volume (doesn't help clarity), but it is limited by feedback as the volume is increased. If I turn the volume past half way, it occasionally squeals very loudly, making it a delicate balance between adequate volume and disruptive squealing. This challenge is increased by the design of the volume knob. While the knob works very well in preventing accidental volume changes, there is no visual indication of volume setting, so you can't tell when it is at that transition point. I solved this by painting 5 lines of different colors across the volume knob so that one or two are always visible. Now I know to turn it so that the yellow line is in the lower half of its visible range. Battery life seems to depend on how much the speaker is actually working. It is rated at 6-8 hours, but I have had it last over two (relatively quiet) days. It is very light and easy to wear and the headset is comfortable. Overall, it meets my needs, but it would meet them much better with less feedback.

this works so well for me in my meeting that I had in front of 100 people. I was very happy that I brought this with me and I used it. They do not have a microphone so I was happy to have my own voice enhancing machine with me. Easy to use easy to carry easy to travel with.

I have been teaching for ober a decade now and I don't know why I never thought to look for something like this a long time ago. I just got fed up straining my voice over classrooms of children who don't listen unless someone is shouting. This way I can keep my voice calm while being heard. It gets their attention. It is small enough to clip on your pocket or waistband without falling. The battery life for me is about 2 and half days worth of class so I think thas is pretty good especially since all you have to do is recharge it. It does get feed back when you walk by things like sinks, desk, etc. This works great for substitute teachers because it doesn't get old to the kids. Going into different classes they don't know what to make of you. Works great for field trips. I think it is a must have for educators who deal with lots of kids at one time. Some of the money we waste in schools would be better spent on staff being equipped with these. It would save adult vocal cords, we would probably get less frustrated because we will be heard immediately, and most kids will respond to the louder voice so you won't have to yell. Yes, kids do get yelled at in school because lots of times they don't respond otherwise.

It was exactly what I needed
