## Questions & Answers

**Q: Can I pair this with a bluetooth headset?  My dad is hard of hearing but can hear through a headset great.**
A: Don't think so. This has a Bluetooth receiver, not transmitter, it won't be able to send signal to your headphones.

**Q: So can both Mics be used at the same time with the one receiver?**
A: Yes both at same time...best wireless mic I bought sounds real powerful good quality and CHEAP

**Q: I have them connected to the party box 710 and if the mic is like 7-8 feet away, speaker makes a really ugly noise. how can I fix that??**
A: This is because of feedback from the microphone to the speakers and back to the microphone. When that happens you have to either move the microphone or move the speakers so that they are not causing causing the feedback.  Speakers should either be pointed away from the direction of the microphone or the microphone should not be pointed toward the speakers.  Hope this helps.

**Q: Granddaughter misplaced charging cable.  Any way to get a replacement?**
A: There are two charging cables, both are standard over-the counter cables. One is type C charger cord, the other is micro-usb charger cord.
