Audio-Technica ATH-CKR90iS 2-Driver In-Ear Earphone with Mic

  • Precision-machined aluminium housings reduce unwanted resonance for improved acoustic response.

  • Drivers of different diameters (13mm and 10.4mm) improve high-frequency response to enable high-resolution reproduction.

  • Aluminium stabilizer improves the driver's linear motion for a controlled response that is faithful to the original sound.

  • A2DC (Audio Designed Detachable Coaxial) connectors offer exceptional durability and optimized audio performance.

  • In-line mic/volume control compatible with smartphones



The ATH-CKR90iS incorporates Audio-Technica’s Push-Pull Driver System to deliver audiophile high-resolution sound quality. It utilizes machined aluminium driver housings that reduce unwanted resonance for crisp mid and high-range audio, while a stainless steel acoustic resistor and bass acoustic resistor provide accurate high-frequency and low-frequency response.
