The electric field between shells is directed radially outward.
The AES has a standard about not connecting pin @1 to the shell. The worry in pro audio situations is that, the shell of portable cables might come in contact with metal objects that are at different potentials. With dedicated cables, connecting pin #1 to the shell is a good idea. In phantom mic cables, the shield needs to be hardwired to pin #1.

5 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity called capacitance …

One of my XLR cables is the monoprice Premiers series with metal connector shell. I came across this article that reviewed this cable and recommended that Pin 1 jumper be cut ? For my purpose of connecting from Marantz Av7706 pre-pro to Benchmark AHB2 or Mark Levinson Amplifier, should I remove this? I am not hearing any humming issue as is.
Apparently it failed a few times untill a capacitor/resistor was added between the USB shield and ground, and a small metal tab was introduced to add better contact between PCB ground and the metal case. This then apparently allowed it to pass. ... so how to handle the shield connection via metal shell is important on Type-A. $endgroup ...
