Audio Technica ATH-CKS1100IS Overview:

With exclusive Solid Bass dual phase push-pull drivers (12.5 mm x 2), the ATH-CKS1100iS in-ear headphones give you premium sound reproduction with Hi-Res Audio and incredible bass. The specially designed drivers reduce intermodulation distortion for amazing wide-range audio reproduction, from deep, rich bass to crystal-clear high-frequency sounds. Audio-Technicas new Dual Bass Venting System also contributes to the high-resolution audio reproduction by positioning two vents in each housing for optimal control of diaphragm movement. The housings themselves are constructed of machined aluminum to reduce unwanted resonance and extend mid-to-high frequency response.

The detachable 1.2 m (3. 9′) cable, with newly developed A2DC (Audio Designed Detachable Coaxial) connectors, is comprised of two separate star-quad cables, one dedicated to the left channel, the other to the right, which improves isolation from external noise and channel cross talk. The cable also includes an in-line mic and control that lets you answer calls and control music and video on your smartphone or other portable device. The ATH-CKS1100iS 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.
