I didn't have whitenoise on the steelseries pro wireless. Are you sure you don't have the mic monitoring / sidetone on max? I use both, the Penrose definitely sounds better for music and movies, however the ease of use, wireless range, and replaceable batteries of the Pro Wireless is a huge plus. Also at this point the mic isn't muffled mess like the Penrose, so I go back to the Pro Wireless when I require voice chat. I received the Pro Wireless as a gift, but if I had to choose one it would be the Pro Wireless, due to all the aforementioned reasons. If you also purchase some aftermarket leather/pleather earpads for Pro Wireless, it doesn't sound too far off from the Penrose.
