AFAIK all Lumia WP devices are compatible with Android In-Line. Apple has changed the coding for iOS devices. But Android phones use the standard.

The Android version works fine for me with a Lumia 830 with Windows 10 Mobile. I therefore assume that they will also work with the L950. As far as I know, all Lumia Windows Phones with Android compatible headsets work according to the standard already referred to by KerenW.
