Before I get into the testing of the product, I would like to say a big thank you to OCZ for releasing 64-bit drivers for the device. More manufacturers need to wake up and realise that the era of 32-bit OS's is almost dead and it's time to move up to 64-bit.
Installing the available x64 drivers from OCZ's website will load you up with their calibration suite and drivers so that you can connect your NIA up to your PC. This is where the fun begins.
Plugging in your headset and strapping it on is simple and comfortable; just follow the included instructional video in the setup screens to ensure a snug fit and optimum positioning.
Now comes a tricky part, calibrating the headset...
When the software asks you to get your 'brain-wave' down to the green line, it can seem almost utterly impossible as it jerks about at the top of the graph. This is because of localised Electro-Magnetic interference caused by items such as cell phone chargers and other power-brick devices.
You will notice if you touch your hand to the case of the filter, it brings your 'brain-wave' right down to the desired level, or at least, it should. But if you are still getting a large amount of interference then you will have to go on a hunt for the noise maker.
