This review is about setting them up for xbox 360.
Be warned if you are planning on buying these for xbox 360 and you use a HDMI cable from your xbox to your tv you will need to buy another part to get them to work. This part is called a "Microsoft RCA Audio cable adaptor" this part is not expensive but its an inconvenience to buy. I went to 2 "GAME" shops, "gamerstation", "best buy" and "maplins" and no one stocks them so i had to buy it from amazon and then wait 3 days for it to arrive. If you use the 3 plugs (red, white and yellow) from xbox to your tv then you dont need to buy the adaptor or the 5 plugs (red, white, red, blue and green) then you dont have to buy the adaptor.
When you have all the parts these are very easy to set up and the instructions are simple and easy to understand.
Another problem you may get.
When i set mine up and started playing MW3 online if someone was to my side and started shooting then the sound would come out equal in both earphones and was very hard to know where the sound was comming from same with any background noise it all came through the same volume in both earphones so i could not tell the direction from which the sound came from. So then i switched the red and white plugs around that fit in the audio adaptor so that red went in white and white went in red (which technically is wrong) but then the headphones started working perfectly. When someone to my right fired their gun i could tell straight away where the sound was coming from.
Dont let these small problems put you off. The sound quality is very good. There is a dial on the control box for game volume, chat volume, mute, expander(widens the sound field for greater directional perception) and bass. I have also asked my friends online if they can hear me ok and they said they can hear me better than when i was using my bluetooth mic. Also this plugs into your USB port for power so there is no batteries or plug (i plugged my USB in the back of the xbox so its out of the way leaving the other 2 USB ports for my contoller charging)Also the cable is very long so there should not be a problem there.
Sorry i have not tried this on PS3 or PC so i cannot comment on those. Hope this helps :)
