This is all a matter of opinion. The x11's are great and have done good for me for 5 months. I just got the ax180s and they work well and i think are less pressure on your head. The skull candys are in my opinion not fit for the match up.
The AX720's.
You can not unless you have turtle beach, tritton or other direct connected headsets
I have Tritton Technologies but i hear that Turtle Beach is better.
There are many companies who make headsets for xbox 360. Here are only a few headset companies I know of: Turtle Beach - The best headsets available Venom Tritton
Xbox 360 and PlayStation 3 - Call of Duty: Black Ops Dolby True 5.1 Gaming Headset - Powered by TRITTON is highly rated on amazon by customers yet is is 199.90 on September 12 2011. I don't know if it goes lower in price but stick in the you cart and watch it Ear Force PX5 Programmable Wireless 7.1 Dolby Digital Surround Sound Headset with Bluetooth by Turtle Beach is even more expensive at Amazon at $212.99 and not as highly rated but does have more reviewers
yes
Fatality are better for gaming whilst turtle beachs remain dominant in streaming and microphone calls.
A good gaming headset for Xbox 360 is a Turtle Beachheadset.
any place that sells videogames/electronics, it is $20.
In my opinion, i think they work fantastically well, but it depends on the version you get and your maximum budget.You can try and search reviews of the turtle beach headset to see for yourself.
Yes but I myself don't like turtle beach I recommend Tritton headsets I think they are better. You cant use 360 headsets on the one
because they suck
