I have used them with my iPhone for conference calls (there is a built-in mic), my iPad to watch videos and my computer (windows) for work. The really work great. I listen to a lot of audio books have never been able to use headphones while I mow the lawn (ride on mower) - with these earphones I can hear the book easily and don't need to blast the volume in my ears! They work without the wire to cancel out loud noises and a/c noise, but you can still hear people talk to you if you don't have music playing through them. I have the apple version of the headphones - they still work on my windows devices but the inline volume control doesn't work with windows so I need to adjust the volume on screen. If you will be mostly using with windows products you should purchase the windows version of the headphones. Hope that helps!
