The flagship of the Solid Bass Inner Earphones, the ATH-CKS90 features the newly

 

developed Dual Chamber Mechanism for enhanced bass and large 13mm drivers for

 

superb clarity and depth. The CKS90s also feature a “two-position post” allowing the

 

listener to adjust the earpiece for better fit and higher sound insulation. 

With increased sensitivity and an improved frequency response the ATH-CKS90 is a truly

 

spectacular earphone.
