Our first attempt, before the mic arrived, was torturous. With masks and distance and ambient noise, it was exhausting to get attention, be heard, or be understood.This. Unit made it possible to do the work while maintaining safe distance. I wore the mic inside my mask. The sound quality is excellent. The controls on the wireless earpiece made it easy to mute or adjust volume when necessary. I didn’t play with the controls on the speaker much in rehearsal, but I was able to pair other devices via Bluetooth to play some musical examples. There is the option to wear the speaker unit or set it somewhere. I was working in a 50 sq. yd. space and never went out of range. The speaker fit in my overall or cargo pants pockets when I was moving around. This helped my singers/actors to locate me instead of just my voice coming out of a remote speaker on the sidelines. The speaker, like any speaker, needs to be pointing toward the listeners, especially in an open air setting. Battery life was excellent. Review: Better than expected sound - Clear sound carries farther than expected. Needed this as a backup for an event in a medium-sized community center gym. It has better sound than the stationary microphone in the gym, and we are no longer tethered to the wired sound system. We are using it for lectures in a fairly quiet environment, but it is perfect for our needs. Even good for outdoor events. Very happy with this purchase. ## Features - 【 25W Loudly Voice Amplifier 】Clear sound, low feedback and 26000sq.ft/2600㎡ sound cover range, This 25W portable microphone and speaker set helps you to speak with a lower voice saving your vocal cords unnecessary stress.

Needed this as a backup for an event in a medium-sized community center gym. It has better sound than the stationary microphone in the gym, and we are no longer tethered to the wired sound system.

Very happy with this purchase. ### ⭐⭐⭐⭐ Works great as an amplifier for Instructors in large areas *by A***C on July 9, 2019* (I am only rating this unit as a amplified speaker for public speaking. I have not tried any of the other function this unit supposedly provides.) I am a corporate trainer and I provide weekly sessions in our large cafeteria/commons area. My audience is seated at tables in an area approximately 30ft x 30ft. I place this unit behind the people and have it facing me. It gets loud with all the other people coming & going. This little speaker does a great job allowing my audience to hear me over the noise of other people. I haven't even needed to turn it up that loud. The first unit I received was intermittently cutting out during and after Amazon's 30-day return policy, so I contacted the seller (ResponseBridge) with questions. I must say that I'm very impressed with how responsive they been with me and addressing my issue. Anytime I see things shipping from China, I'm always a bit leery. So I was pleasantly surprised at the exceptional response & overall communication from the seller. With no questions asked, they offered to send me a replacement microphone. Later, on their own, they informed me that the package they had shipped had some problems in customs, so they went ahead and voluntarily had Amazon send me an entirely new unit. Color me impressed by their customer service! I am a big proponent of post-sale customer service. In this big sea of no-name sellers offering the same or similar products at super-low prices, I don't often expect much of the product nor of post-sales customer support. The only reason I'm even writing all this is because of how impressed I am. So now that I've given out the kudos, let me get into the nitpicking. - The unit has an Echo feature (dial), which is similar to the "reverb" feature found on stereos back in the 70's. I have no idea what it would be used for nowadays. Why would someone want to create an artificial echo of what's coming out of the speaker? *shrugging* - I just took another look at the pictures with the product listing. It lists a wall mount as part of the package. Neither of my packages included a wall mount. Not that I care...I didn't even know to expect one the first time around. - The unit is gloss black. Gloss black = fingerprint/grease magnet. If that kinda thing bothers you, keep a microfiber cloth handy. - The headset is actually two pieces as shown in my attached picture. Once the microphone is attached to it, getting it comfortable on your head is rather challenging since it's not adjustable at all. I find myself fidgeting with the placement of the microphone in front of my mouth throughout much of my presentations. But it's not a deal-breaker by any means. I haven't weighed it, but overall the entire headset is VERY light. So even without any adjustability, it's not entirely a hassle. Just expect to keep the mic close to your mouth. - The first unit I received didn't have any instructions, but I received a followup email with a link to a JPG "instruction sheet". I've attached that graphic to this review. In my replacement unit, I received an actual printed instruction booklet that was a bit more helpful. (See attached. It's all one booklet, but I took two picture to show front & back.) As I noted earlier, I haven't bothered to test the other functions of this headset. So whether or not they work well, or even as expected, I don't know. I'm only knocking this unit for one star because the headset is occasionally annoying. Other than that, at its current price of $98 USD and the exceptional customer service, I have no issues recommending this unit for professional speakers. $100 is a small cost incurred to have a professional presentation. ## Frequently Bought Together - 25W Wireless Voice Amplifier Bluetooth 5.3 | Grade Wireless Portable PA System with Reverb| Rechargeable Speaker 12H Battery for Teachers, Tour Guides, Presenters (2000mAh/S28) - 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.co.th/products/80882727-25w-portable-voice-amplifier-with-wireless-headset-microphone](https://www.desertcart.co.th/products/80882727-25w-portable-voice-amplifier-with-wireless-headset-microphone) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-08-16*
