Pro Tools Echo Troubleshooting

I'm experiencing a constant echo on my headphones while using Pro Tools. This issue started after I installed a new headphone wire to my speakers. I've checked and it's properly connected. We can hear the audio recording but there's an echo while recording

I'm looking for an expert in sound engineering and Pro Tools to help diagnose and fix this issue. The ideal candidate would have experience with audio troubleshooting and can offer quick solutions.
