With newly developed 9.8 mm drivers and machined brass stabilizers that absorb unwanted vibration for clearer mid and high frequencies, the ATH-CKR30iS in-ear headphones give users powerful audio wherever they go. The headphones feature compact housings that are designed to fit comfortably in anyone’s ears – a fit enhanced by four sizes (XS, S, M, L) of interchangeable eartips – and provide a high level of sound isolation. The headphones are also equipped with an in-line microphone and controller for easy answering of calls and control of music and video playback.
