Successor to the best-selling CKS50 model, the CKS55 features improved drivers to
enhance the sound quality. Like the previous CKS50, the 2-postion post design allows
you to adjust the earpieces to find your best fit and improve sound isolation and
the ultra-flexible elastomer-sheathed 1.2 m cord and L-type plug makes these ideal
for use with all portable devices.
