Logitech Unifying Receiver Compatible Wireless Stereo Headset

Hi

I have logitech Unifying receiver compatible wireless keyboard and mouse combo. It works well as for one USB receiver, I can attach two devices. As per logitech, more unifying compatible devices can connected to this one receiver. So upto 6 devices can work at a time using this single item. So I was thinking if there is any stereo headset wireless which is compatible with this unifying receiver, if its possible then would be great.. I searched all over but there is no such headset available which works with unifying receiver, not even from logitech..

I don't think there is any such device, looking over internet I found that they have officially mentioned in a similar question that as of now there is no such wireless headphone device which uses unifying technology by Logitech.
