With newly designed drivers and in-line mic and control, the ATH-CKS550iS Solid Bass in-ear headphones give you portable, smartphone-compatible headphones with superb bass reproduction. The powerful 9.8 mm Dual Magnetic-Field Drivers feature an extra magnet in front of the driver to create a concentrated magnetic field that helps produce full, textured bass. Audio-Technica's specially designed Multiple-Transition Diaphragms add to the expansive bass response, as does the new Bass Venting System, which provides excellent air damping.

The 1.2 m (3. 9') flat cable includes an in-line mic and control that lets you answer calls and control music on your smartphone or other portable device. The ATH-CKS550iS also comes with four sizes of silicone eartips (XS/S/M/L) that fit onto the headphones' two-position posts, supplying a custom fit with outstanding sound isolation. A convenient carrying pouch is also included.
