Noise Cancelling Optimizer. Click on Start to begin the process of optimisation. This is the same as pressing the hardware button on the left earpiece. One bit of information that may come in useful is the atmospheric pressure the optimisation is based on. This is definitely something I am going to try when I’m on a plane.
Sound Position Control. This is a form of DSP that localises the sound around the headphones (front, left, right, rear etc). Not exactly sure what this is used for, but I’ll be guessing this is used in gaming. You need set “Sound Quality Mode” to “Priority on Stable Connection” in order to use this feature.
Surround (VPT). This is another form of DSP which will simulate the effects of sound in a room. The choices are Arena, Club, Outdoor Stage and Concert Hall. I honestly struggle to understand the purpose of this, or why would anyone want to ever use this.
