## Description

SHIDU Wireless Voice Amplifier Bluetooth Speaker 18W Waterproof Portable PA System with UHF Wireless Mic Headset Rechargeable Voice Enhancer Personal Microphone for Classroom Outdoors Tour Guide: desertcart.co.uk: Musical Instruments & DJ

Review: Does a great job relaying speech to distanced musicians in a large hall - I bought this wireless PA device to help an orchestral conductor communicate with players at the back of an amateur orchestra that was meeting under Covid-safe conditions. The 30 players had to be socially distanced and so were spread over a much larger area than usual, and the conductor had to avoid shouting and spreading droplets. Without some kind of help, the players at the back could not hear him clearly. This device works very well. The conductor wears the headset and the speaker unit is placed on a tripod about half way back in the orchestra, which also avoids problems with feedback. In a two-hour session, only about 20% of the speaker's battery charge is used. The headset would need to be recharged more often, but it will also operate while being charged, so its working life can be extended using a USB charging battery block in the conductor's pocket. Used for six rehearsals so far without trouble. One minor drawback -- no tripod mounting bush, just loops for straps and a belt clip; but I hook the belt clip onto an old flash-gun bar, mounted on the tripod.
Review: Works well - Good system and works well

## Questions & Answers

**Q: Will the mic work wirelessly**
A: Yes, and if the power runs out on the mic headset, you can plug in a wired mic  and it works also.

**Q: Can you buy a separate microphone with this product. The 1’s that comes with it the connection doesn’t last more than a couple of months**
A: My one has a wireless micro, you can connect any wireless one as it just needs pairing :-)

**Q: Can you set it so no one else can pair with it?**
A: I am no expert on this but the only way mine works is if I plug a mic directly in to it or use a bluetooth mic but that also has a receiver that plugs in to the speaker so not sure how anyone else could connect to it but as I say I am no expert.

**Q: Can you connect a bluetooth microphone to the speeker or does it have to be wired**
A: Yes you can pair it to a Bluetooth mic

### ⭐⭐⭐⭐⭐ Works well
*by J***M on 26 July 2025*

Good system and works well

### ⭐⭐⭐⭐ Good value and works reasonably well
*by A***N on 10 January 2025*

Used in our art class so students at the back can hear and it does the job. I nearly gave it 5 stars but the default volume is too loud and just edges on distortion as a result. Its hard to find the right buttons to turn it down (black on black) and no confirmation tone, so unless you do it whilst the person is speaking it is completely hit and miss. I tend to press what I hope is the right button twice. Often that works....a minor niggle hence the 4 stars
