Specific Headphones Not Working After Case Upgrade

I recently purchased a Rosewill Nighthawk 117 case and moved my components over. When using my Turtle Beach x12 headphones, I only get sound in the left ear when this wasn't happening with the old case. I've tested with standard aux headphones and I can hear both ears. I tested the Turtle Beach headphones on a different machine and they work fine. What's going on?

Never mind lol the stylized headphone jack just didn't fit my headphones aux cable. Trimmed down the edges of the rubber with nail clippers and it fits and works fine now.
