Help with bedroom audio

[KodaKomp]

So my wifes grandparents live with us and are hard of hearing. They have the TV really loud at night in their bedroom the rest of the family and also them as well would love to figure out an audio solution to have speakers on their headboard without having to run cabling across the floor to their bed. Does anyone know of a cost effective solution that would work? As long as they can watch gold rush and their programs it does not need to be the highest of fidelity just a means to an end.

A denon HEOS system can do that. Its similar to sonos but you can make stereo paired speakers and their HEOS 1 speakers can be easily wall mounted
