Sennheiser HD598 with XBOX360 - need advise please

Hello everyone,

Need assistance from the people who knows and it seems that this forum has plenty to give ... i hope

Last Christmas i bought myself a pair of headphones Sennheiser HD598 and also the TurtleBeach Earforce DSS 7.1 to play on my XBOX 360 - wife and son appreciate silence at night and i had to do something about it.
I must say that this pack together works amazing - the sound is cristal clear and there´s nothing i could have asked more. BUT and there´s always a BUT ... i have one problem - when player single player games i´m in heaven but the multplayer ones are a completely diferent story. I use the standard XBOX360 headset mic to chat with friends and set the XBOX360 to put chat sound thru speakers. What that does is it fades the game sound everytime my friends chat with me. It´s not confortable, it´s not functional and i need to change that.

This is where i ask the AVS forum help: What are my options? what can i do to solve this chat problem while gaming without losing the Sennheiser HD598 + Earforce DSS?

I´m very gratefull for your help in advance.

Kind regards,
JP

Can anyone give a bit of advice please ... i know it´s a big forum and probably there´s already an answer for my problem out there, but it´s a huge forum to find that particular answer ...

Thanks,

What volume do have for:
- Chat Volume ...... ?
- Game Volume .....?

But i believe that everytime someone chats with you your game volume fades away big time in order for you to listen to him, right?

Thanks
