I am a little clueless when it comes to setting up computer technology but did the easy bits ( inserted disc, clicked run, finish etc ) and the fine tuning was done by ASUS support.

## Questions & Answers

**Q: Will this work on windows 10?**
A: ASUS now has new (2021-12) drivers for Windows 10 and 11. (See the ASUS HelpDesk Download link in post above.)

**Q: Can this transmit voice through a built in microphone from the wireless headset to talk to people if I use it for gaming?**
A: Yes

**Q: i have an asus laptop that doesnt have blue tooth is this what i need to use wireless headphones with my computer**
A: Well, Watch out because even if you have an asus laptop this product is useless for Windows 8 or 8.1. I did call the support number and they confirmed that it wasn't happening and that Windows 8/8.1 blows. They suggested I downgrade to Windows 7. If I do downgrade to 7 it won't be to get this $15 part to work- it will be to stop the nightmarish experience of Windows 8. The number for support is 1-812-282-2787. And yes (I'm looking at you, smug sophisticated tech geeks) I should've known better, but I didn't and I hope this saves someone else a little trouble and $14.99. Dang that was a disappointing waste of time. Good luck.

**Q: Does this do multiple pairing?**
A: Yes, you can have multiple pairings with this device.
