A model pursuing the outline of the sound and the depth of the sound image that carries original technology and listens as it listens

In order to enhance the immersive feeling, smooth connection and low distortion ratio of each band are realized.

Equipped with "VESPER" module

The back vent which is often found in drivers for low frequencies weakened the regulation of diaphragm operation and achieved high efficiency, however, large distortion was a bottleneck. 
On the other hand, recent custom IEM realizes a low distortion factor by installing multiple drivers for low frequencies, but it can lead to a problem that it can not be implemented depending on the price rise or the shape of the ear. 
Therefore, we developed a technology "VESPER" that keeps the amplitude symmetry by optimizing the back vent of low frequency drivers, preventing excessive amplitude, and modularized it. 
To manufacture the module, we use a 3D printer and prepare an appropriate filter inside, greatly reducing the distortion of low-frequency drivers.

Equipped with pressure-discharge mechanism

When inserting the custom IEM, the air in the ear canal is compressed, so pressure is applied to the eardrum and the diaphragm.
KL-REF developed and installed a pressure-discharge mechanism to suppress the influence on this dynamic driver due to this pressure. 
We received the user feedback that this pressure-discharge mechanism is effective even when it is in normal use or when the atmospheric pressure changes significantly, so we designed a new module for the BA driver and installed it in this model as well. 
In this model, we are greatly reducing ear clogging feeling and oppressive feeling that I feel when wearing earbuds.
