Pauley plays tech expert Abby Sciuto on the CBS drama, and that enthusiasm for gadgets seems to have bled over into her real life.
Some of the actress' must-haves include her iPad, MacBook and an entire family of Beats by Dre headphones.
"I have the little ones that I keep right next to my couch and then I have the medium ones that I do when I'm recording and then I have my big heavy-duty ones that I use in the studio," Pauley explained.
Hooked Up tours celebrity homes and hangouts to give viewers an inside look at stars' personal high-tech gadgets.
You can watch Pauley's full interview, which includes a tour of Abby's lab, on CNET.com tomorrow.
