Headphones with a rewind cord. The world’s slimmest at 14.9 mm (not including ear pads). The cord is precisely rewound into the main body to prevent annoying tangles in the headphone cord. An ergonomic hanger-type, that fits flat on the ear. The worlds first clip-support function that clips the cord to the earlobe by handling the cord as shown on the photo. This improves contact with the ear, preventing sound leakage (RP-HSR30). Newly adopted sound-isolating ear pads prevent sound leakage to the surrounding environment and provides a gentle contact with the ear (RP-HSW50).
