Setup grounding issue

Hello!,

lately, I bought these cheap set of led strips from amazon and installed them around my desk for ambient lighting but ever since I plugged them in there has been a humming sound in my headphones whenever I touch the metal frame of my desk, I noticed this goes away when I ground myself to my computer case which is properly grounded the led stips are 2 pronged so they aren't grounded. How can I fix this? should I just ground the desk to the computer?
