I have these Sony noise-canceling in-ear earphones (model number: mdr-nc31e):
They came with my Sony Xperia Z2 phone. On the Z2 they kind of work. I can't hear my colleges talking if I plug them in (without even playing music and that's great).
But however if I use them with other devices the noise-canceling does not work. Are there any drivers for example for Windows? Or is this hardware specific?
It's a non-solvable hardware issue. Sony agrees.
From what i've seen it's a 5-pin jack. One of the pins is dedicated for noise feedback. Your PC probably has only 3 pins.
Noise cancellation requires a digital circuit to measure, process and invert the noise signal.
According to this article: "sound processing and battery power are provided by the device they are plugged into". Your PC hasn't got one of those either.
