They patch, do not distort, do not drop out, do not leak, they patch....they patch. Some cables are of uneven length, talking a cm max. SO if you don't like that your cables are 100% identical..DO NOT BUY!!! Otherwise you are very cool to enjoy these. See it as a micro delay on a left or right channel and therefor it adds flavour to the mix.
I think this is all you 'want' to know about these cables, and yes they patch.
