  • Limited by the physical size of driver, Balanced Armature technology were believed that cannot produce full spectrum of sound so that multiple drivers with electronics passive crossover and acoustic damping has to be used to create something with decent bass, smooth mid range and sharp high frequencies.

    We studied existing single BA driver IEMs in the market and the result was not very pleasant. We kept challenging ourselves to see what we can deliver by using the minimum number of driver and how we can make it better.

    Working closely with well-known Balanced Armature technology supplier, we were not satisfied with what they can provide off the shelf. We went one step further, to design new Balanced Armature driver with our own specification. Brainstorm and discussion meeting with the engineers, samples were made and tested over and over again. Multiple rounds of pre-production demo and peer critique with industry insiders. Haka is the result and answer of our hardworking.

    IEM Build & Design

    The Jomo Haka has a glossy black finish to it and the surface is smooth. The shell is made of acrylic. On the faceplate, there is the Haka printed in gold. The gold colour complements the black background. The nozzle is made of brass and it is straight without any metal mesh. I am able to fit the Haka in my ears comfortably.

    Cable Build & Design

    The cable is not your usual stock cable. As stated in the specifications, the material of the cable is made of silver plated copper. At the 2-pin connector, you will see a marking of different colours on each respectively. Red colour will indicate the right side while blue colour will indicate the left side. It is a nice touch so users can differentiate between left & right. There is a memory wire area whereby the cable is being enclosed in a transparent heat-shrink tube. It is not very flexible due to the metal inside that helps to form the shape. The cable is braided with 4 wire conductors. The chin slider and y-splitter are translucent clear. The jack is 3.5mm right-angled gold plated and has a translucent clear housing. There is strain relief.
