Up for sale is a mint condtion Audeze Sine, used about 5 times since purchased. Although I love the sound they are just a bit larger than I expected for general traveling/walking around and will probably switch to IEM's. Nevertheless the sound is amazing and they work amazing well with your iphone to which the cipher cable plugs into directly without any need for . Regular cable is interchangeable with the cipher cable allowing you to use the cans with any source.
