Frequently Asked Questions


Q: The vacuum tubes of M3U are exposed. Will this affect durability or drop resistance?


A: The M3 Ultra adopts an open hollow-out frame structure with reinforced fasteners, and the core vacuum tube area is equipped with buffer protection design.
It has passed multiple rigorous tests as below:

  • Multi-angle free fall test

  • Drop impact test from desktop height

  • Structural anti-shock & continuous vibration test


Conclusion: It features stable and robust structural strength under daily usage scenarios, capable of withstanding regular portable use and accidental drops.


Q: Will there be noise when using M3 Ultra portably?
A: M3 Ultra is equipped with a triple noise reduction solution:

  • Circuit shock resistance: Suppress up to 98% of circuit vibration noise

  • Algorithmic processing: Transient noise suppression efficiency reaches 96%

  • Physical structural shock absorption: Reduce microphonics by over 90% during portable use


No hum or noise will be generated from the vacuum tubes under daily listening scenarios for comfortable audio experience.
