I have not used the built in OMNI mic. What I am using is a vmoda boompro mic plugged into the mic input jack. Works like a champ!

I have sb OMNI and do not get any pops when adjusting the volume. The only time I have heard any pompanos during certain wasapi modes when playing music. I think cause I set 44.1khz wasapi and OMNI is 48khz. Normally no pops.

Can we order an x2 low impedance cable for our x1 phones? Should work perfect.

I have to imagine a price similar to the zxr for this guy. Are these specs superior to the Zxr? I am using headphones on a pc.

I set SBX pro studio on when playing games, have it set at 35%. All other options like crystal voice or scout mode I leave off. You don't need the Dolby encoding unless you are sending 5.1 out the optical. Leave the Dolby encoding off. Note this is not the Dolby surround processing but Dolby...

I would run off the soundblaster z amp and see how you like it. I am pretty happy with mine.

Just picked up a usb modi and a magni from a fellow head-fi member. They are paired with fidelio X1 headphones. Overall a very nice combination.

+1 you should be good with optical out from OMNI.

Thanks for the review! I wonder if the X2 ear pads can be modded to fit the X1? Of course if it is an upgrade in sound I may have to pick it up!

I haven't experienced any game exiting when adjusting the volume knob on the OMNI. Have not played those games you mentioned, though, perhaps it is a bug specific to one of them.

I have only had my X1's for a month or twoooooooo....... if these are worth the upgrade I might have to bite the bullet.  Staying tuned.

The motherboard looks like it has full SBX processing. You should be able to output from to your external equipment without too much trouble and keep the processing.

Look like some beefy beats, there. My pair of X1's have been pretty comfortable. I won't worry bout it much till they start to wear down.

I think my OMNI sounds good for music using my Fidelio X1 headphones. Stomps all over using my iPhone 5s as a source. Very happy for the price.

That is how I have it. Windows set to 5.1 and OMNI control panel set to headphones. I have SBX set to around 35%. Scout mode, crystal voice, all that stuff I have off. Inside the game make sure to set it to 5.1 also. When I not playing a 5.1 source I turn off SBX, such as for music.
