Review: Great for Tour Guides! - I'm a tour guide here in Las Vegas and occasionally walk groups of up to 15-30 people through Fremont Street. For those of you who haven't been here, it is similar to Mardi Gras and Carnaval, lots of music and distractions. Usually, I would have to yell over the din to tell my stories and of course yelling gets pretty tiring, so eventually, you cut you're explanations and stories shorter and shorter as the night goes on, thus doing a disservice to your clients as well as yourself (tip wise). The Aker Portable Amplifier 16W version is just what I needed. -Now I can talk normally all night long and my group can finally hear me. It gets just loud enough so you can hear me like I was yelling, but my voice comes across in more of a conversational tone. With a slight adjustment of the volume knob, I can use the amplifier inside the casinos without disrupting anyone's gambling enjoyment, which is important, since you DO NOT want to upset the Casino in ANY way. -The amplifier projects in the direction you are facing. I can also swing the projector around to my back to talk while I'm leading the group. -I wear the item using the straps as a belt as the clip does seem weak and likely to break. -The microphone is meant to drape over your ears and BEHIND your head, not over. I was concerned about a previous review about the microphone not fitting anyone's head, but have since figured out that they were morons. Trust me in saying that this is a one size fits all mic. -Issues with Feedback were nil as long as I wore it as a belt and didn't bend over to bring the mic close to the amplifier. -Came with an additional amp cord so maybe you could play music from an ipod and talk over the music (haven't tried this) -Comes with a little sack to hold all the items -Seems to hold a charge well. -Charger comes with the item, though the battery isn't readily accessible. Directions says that the battery is good up to a year with constant use. My recommendation is to go with the 16W version as it seems to be the same size as the 14W and you can always use the extra volume in certain situations. The Aker Portable Voice Amplifier is black, small and unobtrusive. The voice quality is good and does an excellent job, especially for the price. (I wouldn't use it as a voice amplifier for singers - it's not that good - lol) Hope this review helps!
Review: GREAT Voice Amp! - 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!

### ⭐⭐⭐⭐⭐ Works great!
*by M***S on October 21, 2013*

My husband bought this for me on the second day of "the Big E" (Eastern States Exposition) in MA. It is a 17 day fair - 11 hours a day talking to people over the noise of a large crowd. I had lost my voice by the end of the second day. He found this item on Amazon.com and bought one for each of us. It shipped immediately and I had it in my hands in less than 2 days. It was ready to go right out of the box - already charged. Easy to work. Could talk in a whisper and be heard across the booth, but not so loud to interfere with other vendors. Has good volume control so you can adjust for your own needs. Had good battery life - lasted through the whole 11 hour day each day. Recharged well each night. Worked so well had other vendors ask where we got it - two of them ordered one for themselves. Went directly from there to the Fryeburg Fair in Maine for another 8 days - 12 hours a day. This unit worked great the whole time. Would recommend this to anyone who needs a little amplification so won't blow out your vocal chords.
