Several colors are available, and shown clearly on the item listing.
They are expensive because they are quality, you get what you pay for...
Volume is adjusted on your device, not via the headphones.
no case comes with these headphones.
Yes, they stay put...I ride my motorcycle on the highway, and they stay put very well even at 90 MPH.
