I have some headphones with cable and 3.5 mm jack for TV, PC, laptop and keyboard. I'm thinking about setting up for some Bluetooth. How does it work and what do I need for it?

You need headphones that already have Bluetooth and a device that has that as well.

So headphones with Bluetooth is clear. But what kind of device? Or do you mean whether my devices such as laptop, TV and keyboard already have Bluetooth?

Some have it, some do not. You do not write anything about your devices.
