Connectable via optical cable or HDMI. It is possible to taste 7.1 channel wirelessly. I was mainly playing a game (COD) and I could hear footsteps clearly.
The sound of explosions is also very realistic and good. I have no complaints about the sound. The leather of the headphones is peeling off quite a bit, probably due to poor use.
Other than that, it is good. If that, please let us know within 3 days you got the item.
