Microsoft Xbox 360 Wired Controller (Assortment)
all official xbox 360 controllers work with all xbox360 variants
The 360 didn't have a regular 3.5mm headphone jack, like the newer consoles do. You need a specific type of headset, or maybe a little adapter, to use it.
It is a Microsoft one
In the description it says that it is nine feet long.
Yes it can. I have a HP Stream and it works great with it. I also use this controller on my PC which still has Windows 7.
Yes, you can operate up to 4 wired ones if the game is 4-player splitscreen compatable.
