All New Frequency Shift Piezoelectric Bone Conduction Driver

Frequency Shift Technology Blessing

The Soul of Craftsman and The Crystal of Innovation

Experience the shock of the new Mentor


The Multiverse Mentor is the newest successor in Mentor series after Mentor V3+, with brand new innovations and technologies. It’s a new miracle created by UM engineers after years of efforts. Multiverse represents a group of unknown universes formed after the Big Bang. The development of the brand-new Mentor is just like the forming of multiverse—we broke through all the traditional technologies and tuning to launch this shiniest Nova into the audio multiverse.


All New Frequency Shift Piezoelectric Bone Conduction Driver

The frequency shift piezoelectric bone conduction driver is a brand-new driver developed specifically for the hearing frequency range of human ears. To ensure our driver’s performance, a conductive palladium slurry with high temperature resistance is applied to the vibrators, and a pure copper substrate is added on top of a double-sided ceramic layer. The performance of our bone conduction driver was also optimized by adjusting the internal structure of the cavity. In this way, our driver is more stable and the vibration sense is more comfortable.


Frequency Shift Technology

The hearing frequency range of the human ear is usually 20-20000Hz, with low sensitivity to sounds below 20Hz and above 20 kHz. Frequency Shift technology reduces the resonant point of the device to less than 20KHz, which improves the sensitivity. The overall sensitivity is significantly improved in the original application environment, and the sound within the 20 to 20000Hz range is mingled in a much more natural way.


The sensitivity of The Multiverse Mentor is greatly enhanced by The Frequency Shift piezoelectric bone conduction driver and Frequency Shift technology. The sound of Mentor is cleaner, stronger, and more focused. Above all the stars.


12 Balanced Armature Drivers + 1 Frequency Shift Piezoelectric Bone Conduction Driver 

The Multiverse Mentor equipped with 4 BA bass drivers that were specially hand trimmed at the back end to boost the bass response. The Multiverse Mentor has more impactful bass than ever seen before.


4 Bass + 2 Mids+ 2 Mid-Treble+4 Treble+1 Frequency Shift Bone Conduction

5-way crossover design gives each frequency range an independent driver group, with distinct levels of sound and rich details. In particular, the bone conduction driver has a new Frequency Shift technology, which allows for a more immersive listening experience.


The specially designed bass driver mingled with the rigorous frequency division gives The Multiverse Mentor a truly unique sound signature. In the repeated competition between innovation and experiment, we created one of the most characterized products. Unique innovation, above the stars.
