Reviews

Noble launched a great, technological marvel hybrid with the Kublai Khan, and they deserve praise for getting four different driver types together in a cohesive sounding package. "This is easily one of the best choices in the sub 3k$ range, with an immersive and highly technical sound with a hint of musicality, thus improving the original Khan."

"There are so many IEMs out there at every price and it can be hard to decide without listening to them. That being said, I can assure you that the Kublai Khan is easily one of the best IEMs I’ve listened to in recent memory, possibly in my life. This is what I look for in an IEM. While the price is fairly prohibitive, the Kublai Khan is a no-brainer for anybody looking for a high-end IEM that you can use for years to come."

Description
The Kublai Khan comes directly from the original Khan line and features 4 different types of drivers, including a 10 mm dynamic driver for excellent bass and sub-bass, a bone conduction subwoofer, four Knowles BA drivers for mid-low and mid-high ranges, and a 10 mm piezo super tweeter.
Basically, we took what we learned from building the multiple award-winning Khan and improved it with greater bass extension with an impact you can actually feel, enhanced mids, and airy and precise highs.
The stainless steel nozzle is equipped with a metal wax protection mesh, and the 2-pin 0.78 mm sockets are recessed. The Kublai Khan is delivered with the 8-core cable from Noble in the version you desire.
