Laptop headphone jack broken?

Ok, so both of the headphone jacks on my Dell studio laptop are not working as they should. When I plug in my headphones in either jack the sound is muffled and can barley be heard, also sometimes sound only comes through one headphone while being muffled. I have to push my headphone connector upwards while it's in the jack for the sound to be normal, this is the same for both jacks. However if anything lightly touches the connector the sound goes faulty again. How can I fix this? (My computer recognizes the headphones)
