According to the specs posted by Best Buy, the wireless connectivity
between the headset and the USB nano receiver is via Bluetooth.

At least Logitech doesn't seem to say exactly that the nano receiver
uses Bluetooth. So maybe it's something else. Device manager might tell
you more about the nano receiver.

I believe that the Logitech dongle works on the same frequency as BT but
doesn't follow the normal protocols. It certainly doesn't show up when
other devices, BT headphones or mobile phones for example, are brought into
range -- no pairing offered. They don't seem to interfere with each other
though since my current desktop has both plugged in and both work unhindered.
