Equipped with the world’s first dual phase push-pull driver system, the ATH-CKR10 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 ATH-CKR10 also features metal-coated titanium housings for a rigidity that greatly reduces unwanted vibration. A stainless steel acoustic resister improves high-frequency response, while a bass acoustic resister provides accurate low-frequency response. Four sizes of interchangeable eartips are included for a customized, secure fit and improved sound isolation.
