Setting up should only take a few moments due to the simple design of this system. All that's required is that either a stereo mini jack or 6.3mm socket be located and the rest will take care of itself. So realistically, setup is as easy as it could be.
Adjustments can be made to allow for users of different sizes and shapes. But we would imagine that most people should have no problems at all with finding a comfortable fit with the KRATOR C-1140 headphones. The top of the head band also allows for a relaxed fit, much in the same way the Steel Series Siberia were designed.
