The "OM" stands for over mold. A process where the wire is solder to the pins and a plastic over mold is applied. This is the same process that the stock cable uses. This allows for a perfect connection to pins which than connect to your in ear monitors. This version does not have a memory which is by design. This allows for a more comfortable fit around your ears. A wooden "choker" is provided which is designed to dampen any vibrations that may occur while the wire is in motion. In addition, you can use the choker to choke up the wire if the wire is slipping off your ears.
Its made with the new and very nicely improved TWag v2..
