In addition, while running a physical connection from the AV Receiver to the headphones is possible, being able to wirelessly connect a headphones is possible as well using either a wireless device that attaches to the headphones or having this wireless capability built in. Additionally many will have special audio systems built in to take advantage of the pros and cons of a headphone so as to provide the best sound to it (with multichannel surround sound capabilities existing as well).
