wireless usb head-set

[goyinlola]

Is there a usb set that can be attached to a single laptop and transmit to and receive from two different listeners/speakers simultaneously? If none, how can I achieve a single usb set connected to a single laptop to transmit to and receive from two simultaneous listeners/speakers?

The Sonos line of speakers can do that, there are probably cheaper alternatives out there.
