This subject is so frustrating !!!!

I am looking into ways to send the audio from my laptop (all audio)
wirelessly to another device, specifically a remote switcher which will
then be connected to a set of wireless speakers ... This is getting
complicated.

Please suggest a product to accomplish this (laptop - switcher).
Please! Looked into USB FM transmitters but the Id need another radio
plugged into the switcher to receive it. Im hugely confused by the
802.11 options, and though Apples Airport yokey looks cool it seems like
over kill. Help!
