I`ve used WS2`s , WS 4`s and now I use the WS5`s and giving my honest opinion I find them just fine being used with my Deus .I really cannot see where Willy Muffits coming from ,no more probably than he can see where I`m coming from.
And on the same token I`ve used a set Chef phones and didn`t think they were anything to shout about .In fact I wouldn`t ever consider buying another pair again thats how much I rate Chef phones . When I put them on It felt like a Vice was gripping my head for one thing, and they were bloody heavy compared with others I could mention !! . So, if nothing else ,this just proves that every set of headphones is seen differently by different people . What may be the bee`s knees to some ,can be a crock of $hite to some one else.
I cannot see why XP would see the WS5`s as not up to scratch for the Deus ,being as they designed them, and branded them, and knock them out for use of them with the Deus. It just doesn`t add up if anything acoustically was amiss with them as why would they would allow them to continue being made ?. It has to be different people`s perception of them due to their hearing ability or disability whichever the case if some of them find , as Willy muffit does ,and people like me cannot see what the problem is.
The only thing I can think of that maybe causing a "difference " Between the WS5`s and the WS4`s which some may pick up as a difference ,is that the WS5`s are in a totally enclosed cup over the ear and the WS4`s are semi closed cup sitting on the ear , maybe the receiving sounds come across to some as "Different" ? But all I can say is I find the WS5`s just fine , with no complaints what so ever with them .(and I`ve used them since they first came out on the market )
