Do all the function work with Android phones? specifically Samsung 7? I have tried a bunch of wireless headphones and some of the features, especially the volume control do not work with Android.

I have paired these with the galaxy S6 and all functions work perfectly. I can't speak to how well they work with the S7, but I would assume that they would work similarly well. I have had no trouble using the side gestures to control the volume and to pause/change songs. The ability to put your hand up to mute the music is pretty nifty too. I will say that the volume control in the headphones is independent from the volume control on the phone, just fyi. If they sound quiet the first time you use them, that might be why. You will need to either turn up the volume on the phone or on the headphones. I personally turn up the volume all the way on the phone, and then increase/decrease the volume on the headphones accordingly.
