Actually it is not a feature, it is a necessity. Signal has to be delivered from the binaural head to the sound recording device and it can not add more noise than a few micro volts. The best way to accomplish it is to use a balanced line. I can't see how it could be possible without using it. Having balanced line, user can use long cables with confidence. XLR connectors of Neutrik brand are of high quality. Length of the included cable is 5 meters. Tasker thin cable is inserted into plastic braided cable sleeve to save space and reduce weight. Without sleeve cable intertwine is guaranteed. Imagine a cold night somewhere in a swamp when your cables are in complete mess. Small details like this are important when you are in the field conditions and start appreciate them only after hands-on experience.
