Do any of you Deus Users use the WS-5 headphones and really like them??? Are they nice and clear like the Killer Bees? I only ever used the WS-4 Backphones. Is there a clear improvement over the backphones (except sweaty ears and the fact that the WS-5's block out all other sounds). If the the WS-5's are an actual improvement over the WS-4's.....then naturally, I will get the WS-5's. Thanks for all feedback. Kevin
