Cable is okay and does the job. Not a lot more to say. Adapters for balanced and unbalanced connections would have been nice. Nothing more to add, I'm afraid. At least these are not $300!
Also, please stop calling replacement/after market cables, upgrade cables!!! Can you sense the insidious bias in the phrasing?
Coming from the included cables from Moondrop Aria and Moondrop SSP, this was a definite upgrade in regard to the SSP cable, but on all accounts, it simple just feels like a quality cable. I opted for the Premium copper, and it made some clarity differences, but not at all the reason to buy. You want this for its prettiness, and that's about it.
I purchased these as I wanted to use my IEMs on my iPhone without a dongle. It works great EXCEPT I had to make sure I was plugging the cable in a certain direction. You would think that all lightning cables would work no matter which direction you plugged it in, but with this cable, I had to mark the connector so I know which way to face up.
The connector eventually snapped off so I gave up and bought a bluetooth IEM instead.
