What is the difference between a Moon Audio Portable Interconnect and a Moon Audio Portable Mini Cable. Basically it is half the wire. The Portable Interconnect is a pair of interconnects that is joined together at one end with a Mini. It is a higher quality sounding cable where flexibility is not a huge issue and more commonly used in a home based Headphone System with either a portable media player or computer. The Portable Mini Cable is more for on the go where flexibility and less bulk is a must, such as with an IPod and a Portable amp.
