The ATH-CKS55XiS features Audio-Technica’s direct-diaphragm driver design that mounts the diaphragm assembly directly onto the edge of the enclosure for increased fidelity and dynamic impact. The headphones also incorporate Audio-Technicas Solid Bass technology, which utilizes an exclusive Double Air Chamber System. In addition to the main air chamber that houses the driver, the earpieces have an additional chamber that operates in conjunction with a specially shaped housing to control and focus the airflow produced by the driver movement and expand its bass output. The result is expansive, rich bass that doesnt sacrifice mids and highs.

The eartips of the ATH-CKS55XiS are designed for maximum bass response, as well, with a movable two-position post that lets you adjust the eartips for the best fit, sound isolation and low-frequency performance. Plus, with four sizes (XS, S, M, L) of interchangeable silicone eartips, youre sure to get the best fit for your ears.
