Unique Melody | The Multiverse Mentor

  • All new Frequency Shift Piezoelectric Bone Conduction Driver
  • Frequency shifting technology
  • The soul of the artisan and the crystal of innovation
  • Experience the shock of the new mentor

The Multiverse Mentor is the latest successor to the Mentor series after the Mentor V3+, with brand new innovations and technologies.It is a new marvel created by UM engineers after years of effort.

Multiverse stands for a group of unknown universes that came into existence after the Big Bang.Developing the all-new Mentor is just like forming the Multiverse - we broke through all traditional technologies and attunements to bring this gleaming Nova to the Audio Multiverse.


  • Magical midrange and vocal performance
  • Great tonal balance across all frequencies
  • Excellent BA bass, in conjunction with the BCD
  • Incredible technicalities including speed, resolution, imaging, and layering
  • High quality, and ergonomic PW Audio cable
  • Comfortable for long listening sessions without fatigue or pressure build-up

"Unique Melody has really hit it out of the park with the Multiverse Mentor.While it's impossible to "crown" a single IEM as being best in its category, I can unequivocally say that it's perhaps the most well balanced IEM I've personally experienced, and fits my personal listening preferences to a tee.

As an all-arounder with flagship level technicalities, the Multiverse Mentor has a magical midrage, a highly detailed yet non-fatiguing treble, and among the best BA bass I've ever heard, aided by the Bone Conduction drivers.

Tying it all together is a laser-focused set of technicalities which I've rarely experienced in an IEM.The Unique Melody Multiverse Mentor has my highest recommendation and is a must audition for anyone in the market for a flagship IEM." - third_eye

"The Unique Melody 'Multiverse' Mentor is without question the most impressive, and I would say 'best' IEM I've heard - it comfortably surpasses both Jewel and Traillii by quite a margin, combining a superb blend of sheer listening engagement, and world-class technical mastery." - Scuba Devils

All new frequency shift piezoelectric bone conduction driver

The Frequency Shift Piezoelectric Bone Conduction Driver is a brand new driver specifically designed for the frequency range of the human ear.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 bonded to a double-sided ceramic layer.

The performance of our bone conduction driver has also been optimized by adjusting the internal structure of the cavity.In this way, our driver is more stable and the vibration sensation is more comfortable.

Frequency Shift Technology

The audible frequency range of the human ear is typically between 20 and 200 Hz, with low sensitivity to sounds below 20 Hz and above 20 kHz.Frequency shift technology reduces the resonance point of the device to less than 20kHz, improving sensitivity.

The overall sensitivity is greatly improved in the original application environment, and the sound in the 20-20000Hz range is mixed in a much more natural way.

The sensitivity of the Multiverse Mentor is greatly improved by the Frequency Shift piezoelectric bone conduction driver and Frequency Shift technology.The Mentor's sound is cleaner, stronger and more focused.Especially the stars.

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

The Multiverse Mentor is equipped with 4 BA woofers, specially hand-trimmed at the rear end to boost bass response.The Multiverse Mentor has more bass than ever before.

4 bass + 2 mids+ 2 mid-trebles+4 trebles+1 frequency shift through bone conduction

Thanks to the 5-way crossover, each frequency range has one independent driver group, which is characterized by a distinctive sound and richness of detail.The bone conduction driver in particular features a new Frequency Shift technology that allows for an even more immersive listening experience.

The specially designed woofer coupled with the rigorous frequency split gives the Multiverse Mentor a truly unique sound signature.In the repeated competition between innovation and experiment, we have created one of the most distinctive products.Unique innovation that stands above the stars.
