Why go with the official Wii U headsets when you can use pretty much anything else?! Phone headsets, PC headsets, or even audiophile headphones with a clip-on mic offer superior options.
There's also a little on the end about setting up your console and TV to not annoy the hell out of people with horrendous feedback, and how to play with the wiimote while using headset audio (it's not as simple as you think!).
