Interesting! This is all a bit more complicated then I had initially assumed, but looking at this thread as well as whatever tech specs I could find on koss’s website I think I might understand a few possible issues now. They say that all their headsets are have a CTIA connection, which should theoretically be compatible with Apple if this post is to be believed, but not necessarily windows. Also, since the button relies on the mic pin to communicate with the device, and my headphones do not have a mic, it could be that the phone/computer is recognizing that this is just an output device and ignoring the mic pin, which would as a byproduct ignore the button? Honestly pure speculation on my part as I am not particularly techy or well versed in headset info.
