I want to amend my quoted statement since I have tried to shorten a set of these cables and it did not work out.
the signal wires are insulated with silicone rubber and that makes them very flexible. They are also very tiny wires so that makes them hard to work with.
The ends are great and the wires are good but shortening them is near impossible because even when you get the sheath off, the wires are reluctant to being feed back into the "wire pants". if you don't use the wire pants, you could make them usable.
[just don't expect to shorten them and you'll be fine.]
fyi, I never did re-install the ends on the cable I intended to shorten. I consider that task more hassle than it's worth.
