Could also be the cable stock they use. Interconnects are usually used in fixed installations (plugged in once and not moved after that) and mic cables tend to take a beating; not so much the way we use them but if used on stage they don't get much love.
Good point and if it was me I would learn how to solder and score some Canare L-4E6S Star Quad Micophone Cable and Neutrik connectors and make some custom cables.
I make mine with the solderless Neutriks. Everyone tells me that it won't work. How can I be so wrong?? They are working just fine for me. I know no one who has actually tested solderless alongside of soldered to reach these conclusions. Until I see the tests, I will stick with solderless. Ma Bell has been doing solderless since the late 50's. But what would they know over there about electrical connections?
I don't think anyone's saying it won't work. Just that the reliability of solderless connectors being used on cables that are constantly being moved, connected, disconnected, etc. is likely to be significantly lower than a well-soldered cable over a longer period of time.
I had a 24 channel snake that was solderless amphenol connectors on one end at one time. It lasted about a dozen shows before I started experiencing channel anomalies and failure of random channels. Finally got tired of it and snipped the ends and soldered standard Neutriks on it and have not had a problem since.
So if the solderless work for you, that's fine. I don't know too many folks who prefer them over soldered cables though. For me, solderless connectors are for emergency field repairs only and are immediately replaced by a soldered connection after the event. I would not use one on a client's project again if I could help it.
Anyway, back to the topic at hand. I don't see why you couldn't use this as a mic cable, except as Flipp has stated it *might* be designed for a permanent install. Those cables are typically less rugged and more "microphonic" than standard cables. You may be more susceptible to handling noise, etc.
