NewFantasia 6N OCC Copper Silver Plated Cord 4.4mm Balanced Cable Compatible with Denon AH-D7200 AH-D7100 AH-D9200, for Meze 99 Classics, for Meze 99 Neo, for Focal Elear Headphone

The left side of these cables fits properly in the headphones - you can feel them properly and securely engage in the headphone. The right side does not. It's loose in the headphone and must be finagled with to get sound. When you look at the metal casing near the plug, you can see that the right side is thinner than the left, which explains why it doesn't engage the headphones properly and is loose.
