They plug into any device and can be used to plug into your wireless controllers for excellent sound and clear mic. They have a full range of colors though it does seem they carry more of the Black and red in stock, but the blue has that lightning color to it and looks really good. Noticed the pricing was actually pretty comparable to the other headsets around it running about $20 dollars. There's a clip area that controls your mic and the volume of the ear buds. The clip canbe attached anywhere and is light weight so that there is not that constant tugging down weighty feel. No case, I would recommend investing in a light one that stores easily in front pockets when not used. I use mine on the elliptical machine and throughout the gym and haven't had any problems. Hope this helped a bit.
