2.4GHz wireless repeater for headset

I have a wireless headset (Creative HS-1200) and it works in 2.4GHz frequency. I would like to listen music throughout my home but its range is not very good.

I would like to know if is it possible to build something like a repeater that takes the 2.4GHz signal from the headset transmitter and retransmits it. If so, could someone post how do build it?

Thank you the for attention
