Difficulty with headphones+mic -- laptop uses speakers instead

I bought an HP Pavilion laptop recently and it has worked great. I have used a headset with it with no difficulty. However, when I bought a Yapster headset I had a problem. The headset mic works fine, but when the set is pluged in to the laptop, the laptop still plays audio out of the laptop speakers (while accepting input from the headset mic). This problem does not occur with earbuds or anything else. The headset works fine in my chromebook.

So my question is, is the laptop incompatable? Or is there a way I can convince the laptop to use the headset as speakers?
