Compact midi leads which make for a tidy installation. I wouldn't want to use them in a situation where they are continually plugged and unplugged but for me they do very nicely in a rack installation. The cables leave the plug at an angle, and the angle is reversed at the other end, giving the options as to which way the cable hangs from your device - which turns out to be fairly crucial for me in a tidy install. A particularly nice piece of design. Also, the plug heads are tiny, which again not only helps tidiness but allows a little more space in a tight installation.
