What are the button impedance for controlling the volume of windows phone

[Windows Central Question]

For example the volume up button on android usually puts up an impedance of about 420 ohms between the mic and GND pin of the TRRS 3.5 jack. So what are the impedance for the windows phone to control the functions like volume up/down and play pause audio?

It's resistance not impedance

I haven't a set of headphones with a volume control, but hopefully someone has a set and a meter. That said I would have thought it would be a similar resistance as you don't get headphones specifically for a phone type (ios/droid/wp etc).
