Featuring Moshi Audio's latest XR9 extended bandwidth drivers, Vortex Pro offers an audiophile auditioning experience so engaging, that you will want to listen to your favorite songs all over again. The 9mm ultra high definition XR9 drivers deliver clean, natural and agile sound over a much wider frequency range with exceptional soundstage and depth. On the other end of the equation is our proprietary triangular RigidBody™ housing, consisting of sintered steel alloy to minimize cavity-induced coloration. The combination renders unsurpassed fidelity across the full spectrum with acoustic transparency and precision. Vortex Pro comes with 3 different sizes of hybrid-injection silicone ear tips as well as a set of memory-foam ear tips for optimal listening experience and comfort. The package also includes a custom silicone carrying case for easy storage and retrieval.
