We're indoors, in a large space with terrible acoustics, and masked so it's really hard for the kids to hear our instructions. We tried the voice amplifier and it works just terrific. Both of our coaches now wear them during instruction and it has saved their voices and helped the kids hear what is going on in class. I highly recommend this. They're a little tricky to learn to use, so give yourself time. Sometimes the bluetooth connection is lost and it takes a moment to reconnect. The mike is worn under the mask for the best amplification. My coaches are really picky and they love these. Easy to wear on the body even during exercise. Highly recommended. Review: The Best I’ve ever owned! - I purchased this to give voice to my Cosplay. I have a 501st Legion approved First Order Stormtrooper. I was drawn to the wireless/Bluetooth capability and reviews regarding sound. I’ve tried many other less expensive versions and was always disappointed. Not this time! Although it’s a little thick and somewhat heavier, it’s the best, most durable wireless amp I’ve tried or seen! Amazing sound quality, capable of using memory cards for additional sound loops or wired microphone if desired. It is hands down worth the extra money, easy to use right out of the box, and has made a huge impact on my ability to interact with people while in costume.

Can the batteries be replaced by the owner?** A: It is a rechargable battery (in both the headset and the amplifier). If there is a limit on the life of the rechargable battery, I'm not aware of it and I've had no issues with my batteries after far more than 3 years. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is a lifesaver & a voice saver! *by N***A on March 6, 2021* What a terrific solution for our soccer program.

HIGHLY RECOMMENDED! ### ⭐⭐⭐⭐ Light weight and reasonably priced. *by K***Y on February 21, 2025* I do school presentations and I never know if the school will have a proper microphone. This is my back-up. The battery will generally last all day, but I charge it over lunch if I am at the school all day. If the school has a dedicated P.A. system I use that answers it will sound much better. I've used it in gyms. It doesn't fill an entire gym, but usually the students are grouped together in one section. It claims it works for groups of 100 people and that sounds about right. I doubt it would sound good with musical instruments, but it works for voice. ## Frequently Bought Together - Wireless Voice Amplifier with Bluetooth 5.3 | 18W Portable PA System with Waist Clip, Waterproof Rechargeable Megaphone Microphone and Speaker for Teachers, Tour Guide, Presentation - W WINBRIDGE Voice Amplifiers Speaker Carry Case Cover Bag with Mesh Pocket Zip And Snap Hook Fit USB Cable Wall Charger Phone WB010 - WinBridge Portable Collar Clip Microphone 3.5mm Audio Compatible with All WinBridge Voice Amplifiers S6 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/69920626-wireless-voice-amplifier-waterproof-bluetooth-speaker-with-microphone-m800-18w](https://www.desertcart.pl/products/69920626-wireless-voice-amplifier-waterproof-bluetooth-speaker-with-microphone-m800-18w) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-09-03*
