I am looking into some monitors, such as some of the Behringer Truth models (I can get a good deal at the store I work at) and hook them up to my computer for recording. I noticed that there isn't any type of headphone jack on them. How can I fix this so I can use headphones with these monitors? There isn't any type of headphone jack on my computer tower so I can't plug into there and the monitors dont have any. Sorry for all the questions guys... I am a recording newbie! Thank you for all of your help!
