Not sure if your headphones support it? Google their model number with the word multipoint to find out. Even budget headphones from some manufacturers like Jabra have Multipoint. Not all headphones support it, but most mid- to high-end headphones from manufacturers like Bose, Sennheiser, Beats, and so on do. Many Bluetooth headphones, though, can connect to more than one device at a time thanks to a protocol called Multipoint. That’s how headphones have always worked. Plug them into your computer, and you can only use them on your computer, until you unplug them and plug them into something else. Wired headphones can only connect to one device at a time.
