Whether I'm addressing a small group or a larger congregation, the clarity and strength of the sound projection from this speaker are simply unmatched. It has the power to effortlessly fill the room with my voice, ensuring that everyone can hear my message loud and clear. Speaking from experience with various wireless speakers, the WINBRIDGE Voice Amplifier stands out. Its ability to maintain crystal-clear audio quality even from a considerable distance is remarkable.

Review: Awesome gadget with one flaw - I love this little amplifier. I use it daily as an Adventure Guide on the river. It is plenty loud and I really love having the Bluetooth capability added to it as well. One critique is that I believe it is a design flaw to have the power port and the microphone jack on the same side. While using the microphone headset, the power port is exposed to the elements with no protection from water (rain, river, dirt, etc.) But this amp is very durable, plenty loud and easily carried.

## Questions & Answers

**Q: does this need a sim card for the recording function?**
A: Yes, this voice amplifier need a TF card or U drive for the recording function. The item itself doesn't have memory to save recording data. 
Kindly be informed that it is TF card but not sim card.

Thanks

**Q: Is it possible to disable the Bluetooth so people cannot have access to the speaker while teaching?**
A: Hi, sorry to tell you that you can't disable the Bluetooth directly. However, kindly inform you that people have to manually press the button M on the speaker to switch to Bluetooth but NOT like other devices could directly be access to it. 

Thank you.

**Q: Can I set up 2 voice amplifers for a larger room and just use one mic?**
A: Hi,

This model voice amplifier comes with wired headset but not wireless, so you can't set up 2 voice amplifier with one mic. However. This voice speaker is specially designed for outdoors, so even it is 10W output powerful but it louder than the 25 watts. 

Or if you would like to choose a more powerful voice amplifier, kindly suggest you our another model S92 25W portable pa system (with handheld mic and headst mic ) or H2 30W pa system. If you are insterested in them, please click the following link for more item detailed information:

Thank you.

**Q: I teach water aerobics is everything water proof?  I need a headset I can wear while I am in the water instructing the class**
A: This wouldn’t last in the pool. It’s more water resistant. The plugs have covers to keep water out. But if you want to plug a headset in, your going to half to remove the cover and exposing the plugs. I’d say it would be fine for poolside if you can find a water proof Bluetooth headset.

### ⭐⭐⭐⭐ Better, louder than the 25 watts VoiceBooster.
*by M***E on May 7, 2018*

What I like the most is the big sound for only 18 watts and such a small unit. I used it for large groups Team Building (120 persons) outdoors and everyone could hear me clearly. I own 8 of the VoiceBoosters also purchased at Amazon and they where nice for 25 watts, but this one sounds better and louder than the 25 watt VoceBooster. And Its more confortable to wear. The WinBridga has a great volume for such small device. I love it when playing music from my iPhone via bluetooth. The feel in you hands is that one of a well built product, solid. What I do not like is the is missing a MUTE button, I know I can always bent the mic away but that will also produce more feedback. The VoiceBooster doesn't have the mute either but the analog on of is easy, the WinBridge has a digital on of so to shut it off or on you have to wait. Another setback is the volume control when playing music with the bluetooth, it doen't have low volume, it only plays loud and louder. I tried controlling the volume on the play device but the same thing happens. (volume control and the back and forward buttons are shared for both functions. I will probably be replacing all my VoiceBoosters for this WinBridge once the WinBridge passes my test of time.
