The best I can figure is that electromagnetic waves can travel through a vacuum. It isn't sound, so the lack of air doesn't interfere with its function.
Although you won't hear all the sounds in space, it becomes possible with the help of some matter and a converter. Radios will always be a necessary tool because most sounds won't be detectable in space.

This is interesting. There are some areas of the cosmos that have copious amount of gas. And I thought it was only me. Galaxy clusters being those areas. A new way of interpreting these space sounds use a technique called Sonification. But, don't think if you were parked around one of those galaxy clusters you'd hear this sound. As, the technique takes these sounds that are hundreds of quadrillion times lower than the human range of hearing to create the sound. That's mighty low and quite a few zero's. One hell of a subwoofer.
