I can't hear anything out of my headphones

Hello, I can't hear anything out of my headphones when plugged in to exterior speakers. Sound is perfect from these speakers otherwise. Headphones plugged into the front of computer work. I have tried several different sets of headphones same thing. Thanks for helping me

The port on your exterior speakers may be broken. Considering you have tried other headphones, that would basically confirm it.
But, have you tried plugging the speakers into another port and/or wall socket if they need power this way? It could be that they are underpowered. Have they worked with the headphones plugged into the speakers before?
