Firstly, I have no experience of the Pro+ so I can not do a comparison with that product.
I'm using these on a pc and connected them to the optical port of my soundcard. Setup is FIDDLY, but worth it.
With a dolby digital live enabled soundcard these sound fantastic, easily the best sound I've ever had in games.
They also handle music very well but they do not shine in this area as much, but for gaming this is the best sound I've ever had.
I had a set of the Ax Pro's and these have better sound quality.
