## 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
