For power cables, there might be some benefit if there was a problem 
from a co-sited transmitter, but one would need a common mode choke at 
the equipment end, and unless the power supply was well balanced or 
differential mode filtered, at the power supply end.  For transmit, 
your biggest source of differential mode power supply noise is your own 
PA stage, so, unless you have good decoupling internally, I don't see 
that it would help to balance the external lead.

My suspicion is that good differential mode filters on the input might 
be a better approach.

Headphones might benefit, but you would need a common mode choke, or an 
output transformer.  Also, I suspect that headphone lead pickup tends to 
get injected in common mode.
