Seeking advice: PC and PS3 Audio through single headset.

[Velo_Vandore]

I have a PC upstairs, and a PS3 downstairs. When the children are asleep in the bedroom, I like to play downstairs on the PS3.

I am looking for a wireless headset with good range so I can keep it connected to Skype or other 3rd party voice software on the upstairs PC while playing downstairs on the PS3 console.

The second part of the question is about how to get the PS3 game sound coming through a wireless headset at the same time as the sound from the PC upstairs. I know the simple solution is to have the PS3 game sound coming out of the TV and just have the headset on one ear, but this isn't ideal as it can mess with the mic position and become uncomfortable. Is there any headset that can receive audio from two sources, or some wireless audio mixing device which I can link to one headset?

I've been googling but I don't have much knowledge about audio terms so any help would be great.

How is everyone else handling this? Just mute game sound? Single ear headset with game sound through TV? Voice chat through speakers on laptop / mobile device? Interested to hear about your setups and how you're getting on with these.

EDIT: Also have an IPhone which may / may not be relevant to any possible solutions.
