  1. I think the author started to confuse TRS (tip, ring, sleeve) with TS (tip and sleeve)?
    TRS is suitable for balanced or stereo transmission, whereas TS is unbalanced or mono.
    TRS and 3-pin XLR, happy to be wrong here, have the same transmission capabilities and it’s often just the size factor that determines which is used
    For instance many small form audio interfaces just have balanced XLR inputs, with TRS outputs as it saves space

  2. Your article although good, has some errors. TRS jacks can also transmit balanced single exactly the same as xlr connectors. Your article mentions in a few places that it can’t. I would suggest you change this and mention that TS jacks (mono) can’t deliver balanced signal. That is TRS two channels of audio, one in phase one out of phase and a common ground same as xrl when used for this purpose (depends what you plug it into) TR Jack one audio channel one ground.

  3. TRS unbalanced? Really? TRS connectors have two signal wires and one ground, just like XLR. TRS audio connections (not headphone) are balanced. A TS connector is unbalanced.
