Product Reviews

  1. Works perfectly in my classroom!

    Posted by Unknown on 13th Mar 2017

    I purchased the VoiceBooster MR2300 for my music classroom. I primarily purchased this product to use during rehearsals and when we play instruments in class. I was extremely impressed with the level of amplification for such a small system, and my students were able to consistently hear me better. I am looking forward to using this system again in class and am so thankful I found this amplifier so that I could take better care of my voice!

  2. Amazing product

    I was very excited to find this amplifier on line and was extreamly pleased with it when it cane in the mail three days after ordering it ! It truely does everything advertised. I am going to use it for costuming and it works wonders under my helmet

  3. The best "fanny pack" amp I've found. Definitely buy the 20 Watt model.

    Posted by Swing-Dancer on 26th May 2016

    I teach Line and Couples' dancing to groups of 20-30 dancers. I saw other instructors wearing various "fanny pack" amps and asked them all how they liked them. The instructors who had done the most research either bought VoiceBoosters or were planning to replace their current setup with VoiceBooster. That's when I first heard of the VoiceBooster brand. They also highly recommended I spend a little bit more and get the top level, 20 Watt amp. I did, and I like it so much I bought another one as a spare.

  4. Voicebooster SAVES the voice of teachers!

    Posted by Len Kravitz on 26th May 2016

    This product works so well and is so helpful in saving a teacher's voice.
    I use it every day in my classes.
    However, a couple of classrooms that I teach are large with 100plus students. In these lectures I need to turn the volume up on the Voicebooster. I find it sounds just a little 'metalic' or 'tinny' when the volume is pushed towards its limit. Not sure if anything can be done in this situation but want to bring it up to you.Thank you!

  5. The best amp by far in this price range

    Posted by Don Karns on 5th Jan 2016

    VoiceBooster amplifiers have proven to be the most durable, long lasting convenient amplifiers I have encountered. In an open area they provide ample volume, but if there are any buildings nearby the VoiceBooster will be incredibly loud and the sound can cut right through the walls or Travel along the wall. The battery life between charging is amazing. Advertised as lasting 15 hours, it would be---15 hours of use. It could hold a charge for a month, if you only used it some each day. After several years of use you can buy a another battery, so these amps last indefinitely. They can be used in light rain, although if they get drenched they quit working till they dry off. This newer 20 watt model is not so much louder as it is a more clear voice and tone. I have never heard of anyone regretting the purchase of an VoiceBooster amp. Voicebooster.com is a reliable distributor you can talk to, unlike Amazon or eBay . I have used each. I advise buying through voicebooster.
