It seems that without a keyboard with a balance out anyway (our has a preamp in the headphone out that is also unbalanced).. that it's all a moot point anyway. Still, it's good to learn more about the headphone issues from your viewpoint... Still, I've heard it differently, even recently, from an electrical engineer who stated to me that they are the same conductors as 1/4 outs.... and the TRS headphones are indeed balanced.
I guess that's where I was mentioning arguement. I am no electrical engineer though, so I will stop this here. There's nothing more that I can offer on those more technical points. My only observation, on my own, is that they rarely seat very well and the static on line can sometimes come from the posts not actually being properly seated. Hmmmmm
