It was packed perfect for transit & very protected in the box. Everything required was in the box. Once I had figured my way around the unit I tested it & the sound feed back was crystal clear. It weighs a little heavy for what I need it for which is to wear under my 501st legion Tie Pilot costume but that can be worked out. The digital display stating current battery level is a breath of fresh air It will tell you when it runs low & requires a charge. It has voice AI when you first start it up & you haven't got the mic plugged in. It asks you to attach the mic cable. The instructions it comes with regarding the mic is for a wireless mic this unit came with a wired mic. All in all just at first glance I'm very pleased with the purchase. ### ⭐⭐⭐⭐⭐ Works exactly as described *by A***5 on Reviewed in the United States on 5 November 2021* I belong to a small group who get together to play bingo. Our old speaker system broke. We needed something portable and could amplify our voice so members could hear the numbers being called over various conversations. This worked beautifully. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/229356987-responsebridge-18w-waterproof-voice-amplifier-with-portable-microphone-headset-18w](https://www.desertcart.tn/products/229356987-responsebridge-18w-waterproof-voice-amplifier-with-portable-microphone-headset-18w) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-08*
