Descending directly from the lineage of the original Khan, the Kublai Khan features 4 different types of drivers, including a 10mm dynamic driver for superb bass and sub-bass, a bone conductor subwoofer, four Knowles BA drivers for mid-low and mid-highs, and a 10mm Piezo super tweeter. Basically, we took what we learned from building the multi-award winning Khan, and improved upon it with greater bass extension with a rumble that you can actually feel, improved mids, and airy and precise highs. We are also happy to note that electromagnetic interference from the Apple dongle is not an issue with the Kublai Khan. The stainless steel nozzle includes a metal wax guard screen, and the 2-pin 0.78mm sockets are recessed. The Kublai Khan is shipped with Noble’s 8 Core cable in your choice of termination.
