Metal Housing, Hybrid Drivers

Ostry is known for making well-liked, budget-friendly IEMs like the KC06, and the KC07 model brings those qualities to a higher-end design. It features a dual driver configuration, with one custom Knowles balanced-armature driver and one 10-millimeter dynamic driver per ear. The metal housing is CNC machined, anodized, and designed to fit comfortably in the ear. The Litz cable uses a combination of eight-core single-crystal copper and silver-plated oxygen-free copper, and the MMCX connectors make for easy cable replacement down the road.
