Best setup for audio directly from PS3 through USB?

[SweetIvy]

Hello everyone, I started searching for info about the best headphones to be used with my PS3 config and I've found tons of info, however I have some doubt about the optimal setup for my own configuration:
 
1- I use a monitor (not a TV) and I want the audio to come directly from the PS3 to the headphones, can USB headphones do this?
 
2- I think I need headphones rather than a headset because I am in a noisy environment so I need max isolation possible, am I correct that over the hear headphones are best (actually in-ear are probably even better but certainly not for quality?).
 
 
Through my reading I think my optimal choice would be USB dolby headphones, is it correct?
If not, what am I missing?
 
I've also read about amp but so far I failed at really understanding whether I'd need them.
 
 
I'll mainly use the headphones for PS3 gaming, sometimes (rarely) Pc gaming as well.
 
Currently I've got a SONY MDR-XD200 but I'm plugging it through a 2.1 audio system while I want to plug the new headphones directly to PS3 and maybe find something better at isolating external noise (and some higher audio quality?).
 
Thanks in advance,
Ivy

you can use either optical or RCA. Connect those to a DAC or Amp, respectively.
 
There is no USB audio path for the PS3 afaik.
