They are less flexible than the original meze cable and the meze balanced cable (the cheapest option). For me is not a big problem but flexibility is not the biggest strength. The sound quality is very good though especially for the HD6XX - HD 58X and 4XX.How flexible these cables are compared to the stock one?
Which one do you own? The regular OCC or the SP-OCC?
I am not aware about this option to be honest since I bought them some time ago but I would think regular OCC.
