Flat Impedance Balanced Armature Earphone

Flat Impedance Balanced Armature Earphone (FIBAE™) patented technology is the world’s first, revolutionary, In-Ear Monitor design providing flat impedance and phase. By changing the Balanced Armature driver’s character from inductive to resistive we solved one of the oldest problems in the industry – dependence on output impedance of sound source for correct earphone output. With FIBAE™ technology your earphones will always perform best from any DAP. Single and multi-driver configurations available.

Geometrical Sound Outlet

GSO is a calculated parallel wall structure inside an otherwise round nozzle.
Geometrical Sound Outlet serves multiple functions – firstly as a support structure to increase the rigidity of the nozzle, secondly optimizes the dimensions of the nozzle and reduces the cross section size, finally it works as a horn structure increasing high frequency extension.

Pressure Optimizing Design

Pressure Optimizing Design is our in-house developed technology to reduce the pressure in front of the driver and influence its response by properly tuned acoustic filters.

Ultra Planar Speakers

We equipped Apx with an Ultra Planar Subwoofer delivering range only up to around 80Hz and an Ultra Planar Tweeter for range above 10kHz. Planar technology offers near limitless response on both ends of audible frequency range. Planar subwoofer supports Dynamic Driver in order to create the most natural bass attack and decay without unnatural bass boost to compensate. This woofer is strong enough to create perceivable vibrations enhancing listing experience. Planar Tweeter supports Balanced Armatures by adding extra air and extension, the choice of speaker and its application allowed to retain correct high frequency tone and speed.

Precision 3D printed housing with calculated waveguides

Each driver inside the shell is meticulously positioned in a 3D printed coupling structure, with calculated and proper distance to the sound outlet, accounting for frequency and time domain. By removing variable elements such as a typical soft tubing, we increased the repeatability of the response across the whole production run.
