Here's a little deal I took advantage of today.
They've got the Tritton (MadCatz) Wii U Kunai (misspelled on their website at Kunia) on for $7.95

These headphones have a single 3.5mm jack that would also work on PS4 and Xbox One (with the headset adapter)... so all well and good, right? Well, if you pair it with this cable (which can be found cheaper elsewhere):

You can then use it on your PC, as it splits out the mic signal from the headphone signal.
All of a sudden, you have not-terrible set of headphones for your Computer, Wii U, Ps4 and Xbox One for the price of $16 after taxes.
Now, the website is out of stock, but they've got plenty in store (at leat in London). The red ones are also on for $7.95 in store, too.
The exact same headset but in the "Universal" variant, goes for $60 on their website, and other places too.
