The ATH-CKR100iS in-ear headphones deliver high-resolution audio that’s true to the original sound. The unique push-pull system incorporates two facing 13 mm drivers that generate phase-aligned audio signals that are mixed to compensate for each driver’s inefficiencies, while providing an equal and tailored response without artificial coloration. By reducing intermodulation distortion, the push-pull drivers deliver extended frequency response for life-like sound. The headphones’ high-rigidity titanium housings reduce unwanted resonance, and their design positions the drivers for optimal performance, while ensuring a comfortable fit with excellent sound isolation. The performance is further enhanced by high-precision stabilizers that ensure linear diaphragm movement for faithful high-resolution audio reproduction.
