JBL Tune 760NC Overear Headphones Left side not working while using wired mode

When im using these in wired mode, the left side has no audio unless I hold the wire near the port slightly tilted.

At first I thought it was a wire issue so i bought a new wire but it still doesn't work properly. I tried it on multiple devices but the same issue remains.

How do I fix this? They work fine in bluetooth mode but that's not always an option for me.
