actually, i have used both the tritton ax pros and currently have the turtle beach dx11s.
the trittons do have 4 SMALL drivers compared to the turtle beach headset which has 2 big ones.
with that saying that the tritton has 4 small drivers is everything is high pitched even with the sub turned up. the sub only affects the explosions. I do mean ONLY the explosions. This saying that everytime a harrier comes in it VERY deafening and i almost threw my headset it hurt (yes i had my volume low also.) Another note, the light in the left cup went out in a couple weeks.
With the dx11s, i have the bass boost which makes everything deeper. the sound is much better to me. even though its simulated, you WILL NOT be able to tell the difference at all.
i currently have the dx11s and say it is a better choice. especially if you want to save your hearing :p
