Yes, but it depends on what you mean by regular. Most plain headphone/mic combos have no built in amplification so sounds are very quiet. Good gaming headsets can use the xboxes usb ports to amplify the signal giving you much better sound. Pay 20$ and get the very lowend turtle beaches. Even these are better.
Yes, regardless of the storage capacity you can use a headset with the system. Make sure the headset you buy is compatible with the Xbox 360, then use the input on the bottom of your controller to plug it in.
There is a plug in the bottom of the 360 controller. Plug the headphones into there.
Yes you can! With any kind of headphones. But it won't if the hole isn't big enough for it.
No you need XBOX 360 controllers.
The original Xbox controller doesn't work on the 360.
Yes you can.
you don't need too, you can use xbox games on xbox 360
sometimes but not always
The 2 items you gave are 2 different things. Turtle Beaches are headphones of the Xbox 360. An ethernet cable connects the Xbox 360 to your router/hub to give it a internet connection.
One of the great features of the Xbox 360 is the ability to communicate with other people. The best way to do this is to use a Head set. The handsfree headset consists of headphones and an attached microphone, much like those used by office workers.
yes you can use the xbox 360 controllers on the xbox 360 slim. I use my controllers from my old xbox on my new 360 slim.
You can not play xbox 360 games on an original xbox, however you can play some original xbox games on an xbox 360 console.
No.
