I am writing about the CKS90 LTD II .

One thing to say ..GET IT if they are still available . I have tried Westones,Shure,Kiliscp..whatever, Bose , Monsters , Beyer Dynamics etc all of them more expensive ,;some even 3x more. None even comes close except the ATH-CK10 albeit a higher price.

These buds made all others sound puny and lifeless by comparision!
The only ones that can beat these guys are the top-end Grados I own and the like,but we are talking about a different catergory of fish here!
