Couple things I noticed last night fooling with the BBees. This could be true of any cable under these situations, but I think the BBees construction may be signifigant in the following setup:
1 Low volume sound source close to the mics
2 pre's gain set way high (to 11 
)
3 cables loosly coiled on the floor
The other thing I noticed right away is the stiffness of the cable's teflon sheath keeps them wanting to coil up if left on their own. It's not that they are spring like as much as they will simply tend towards forming loops. I can see if care is not taken to uncoil them during set up then you could find and "ass hole" or kink develop. I'd rather not test to see if the cable will sustain a sharp bend and not finding such a kink in the loop is a step in that direction. This could stand some comment from a manufacture's rep.
All for now, I may edit/add later.
all cables will transfer mechanical vibrations to the mics, no matter what. i agree with your testing results. if you're recording dead air and have the gain cranked at max, you're going to hear EVERYTHING through headphones. however, we'll never be faced with such environment since most of our taping is loud PA level sound sources.
as for the stiffness of the cables due to the teflon, it's quite flexible for the material used. i tend to roll up my 15' into a 9" roll for my bag. when i unpack at a show, i usually unroll it and straighten it out where needed. my experience is that they do not have a "spring" or a "coil" effect.
regards to sharp kinks... they will support a full 180 degrees bend. (i just bent mine and bent it back). i wouldn't recommend it day after day, but if the situation calls for it, then i think it passes that test.
