[quote name='rgd2blck']Regarding PC surround sound with the AXPro, my model comes with an adapter (G9) that bypasses the control box and allows me to get 5.1 surround sound because my PC sound card supports 5.1 surround sound. I just plug in my headset into the adapter, plug the adapter into my sound card's 4 ports and shut the control box off. Fortunately I can leave my adapter in my PC all the time. If I had to keep switching it out there is no way I would use it.
For the AX720, I know the G6 adapter does not provide surround sound however you can use optical (if your sound card supports it) to deliver PC surround sound. USB mic to chat.
Regarding the AXPro vs AX720, PCWONK is the only person who has mentioned simulated surround sound and it is very important. The AXPro has 4 speakers in each ear to deliver "true" surround sound. The AX720, like the Turtle Beach headsets, has just one speaker in each ear to deliver "simulated" surround sound.
I listened to both the AXPro and the Turtle Beach X4 (not the X41). I prefer simulated surround / one speaker in each ear because with the AXPro and its four speakers in each ear the sound differentiation between the front and rear channels is not good. Basically something in front of me sounds the same as when it is in back of me. I've tried changing volumes in each channel as well as time delay settings on the control box and it's just not working. This was not the case with the single speaker in each ear TB X4, and I assume it will not be the case with the single speaker in each ear AX720. XphoenixX touched on this much earlier in this thread.
Also, having just one speaker in each ear will hopefully make the headset lighter.
If I had to pick between the AXPro or the AX720 without testing them first, I would go with the AX720 simply because it is cheaper. CAG, after all.

Having experienced both true and simulated surround sound, my preference is simulated, so I pick the AX720. If I ever find it under $100 I will buy it to replace my AXPro.[/QUOTE]
This is exactly how I feel about the differnce between 1 driver simulated surround vs. 4 driver surround. I have the ax360's and what you said about the volume and delay settings is exactly how I feel. Also what you said about the sound differentiation I have also noticed this. I also do not feel like having to constantly tweek the inline controller for each different game I play to get the right sound. The ax720's "just work".
