I am not sure how much the Triton's cost, but I'm assuming a pair of good headphones would be better than the AX360 as a whole. I used to be impressed with gaming headsets until I got a hold of a better pair of real headphones. I could not go ahead and use a gaming headset again... microphone for me. Gaming headsets can be good if you care about cool sound effects and the like, with the help of the included software.
And James, I'm thinking that also. There's microphones that could be clipped to the monitor as well, so as long as the peripheral being used isn't loud as heck (and a wheel might be, I don't know), then you should be fine.
