so, i want to play music wirelessly from my notebook. i don't have a home theatre system to play to, so i need to buy speakers, but i don't want to have to buy a receiver and speakers. i originally thought that there would be some kind of device to which i could connect wirelessly, which would connect to a set of speakers. all that i've found so far is a roku soundbridge which would connect to my router then to a receiver/speakers.
does anyone know of any way wireless speakers available for computers?
