So, TRS plug are designed in a way that the the ground connection is made first and disconnected last.
I'd like add a switch to the ground of TRS jack output. Firstly to incorporate a mean to switch between active/passive/no ground, second to prevent signal shorting to ground while plugging/unplugging, and thirdly to turn off the headphone (by leaving it with an open circuit).
So, is it a bad idea to disconnect the ground of a TRS jack while leaving the signal connected?
