Depends on the headset and the laptop.
If the headset is dual 3.5mm jacks (one for mic and one for headset), you would need a laptop that has both of those ports as well. An adapter from 2- 3.5mm jacks to go into one input/output combo port may not work. However an adapter of 2- 3.5mm jacks to a USB probably would.
If the laptop only has an output port, then only headphones will work, no mic.
