The intended pairing. Whether it carries stereo or a balanced mono pair is a property of the devices, not the connectors.
6.35 mm TRS plug
Three-conductor quarter-inch plug. Stereo, or balanced mono, depending entirely on what the device does with the ring.

What it mates with
Mating is directional, so the two lists below are genuinely different: a TS plug in a TRS socket and a TRS plug in a TS socket short different things.
6.35 mm TRS plug used as the plug
Partial fit
6.35 mm TS jack
Mirror of the TS-into-TRS case, and the reason both directions are stored separately.
- shortThe plug's ring rides on the jack's sleeve, so whatever the ring carries is shorted to ground. A stereo source loses its right channel into a short rather than into an open circuit, which some outputs do not like.
6.35 mm TRS plug used as the receptacle
Nothing recorded with this connector as the receptacle.
