They will all control the media player (native or even most third party apps) to skip tracks, start, pause and have a local volume control (you can independently set the output level on your phone, the headsets will control the volume using that level as a reference (i.e., 0 to max volume=to the bt output level you set on the phone). The equalizer settings on your media player should also pass through to the headset (some advanced features such as 7.1 and spatial effects are sometimes disabled by the local app for BT output vs. wired headphone output). Good luck.
