Generation & platform

The scores rank quality. This is the other question: is the newer one actually newer technology, or the same platform in a new shell?

Same generation

The FiiO FX17 is 5 years newer, but it is the same generation of hardware: nothing in the radio, the codecs or the noise cancelling separates them. Nothing separates them on convenience features either, so the choice comes down to tuning and price. For 5 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said

DUNU Zen Pro

The DUNU Zen Pro is a premium single-dynamic-driver IEM that moves toward a more neutral, balanced tuning compared to its predecessor, while retaining a likeable and well-rounded character. It combines excellent build quality, comfortable ergonomics, and a generous accessory set, making it a strong all-rounder for critical listening. The sound emphasizes textured bass, smooth lower mids, and extended treble, though it is somewhat tip-dependent and less impactful in sub-bass than the original Zen.

  • Pro:Neutral, well-balanced tuning
  • Pro:Excellent build and premium feel
  • Pro:Comfortable fit with good accessories
  • Con:Sub-bass rumble is muted
  • Con:Bass slam is less forceful than predecessor
  • Con:Fit is sensitive to ear tip choice

FiiO FX17

The FiiO FX17 is a premium wired tribrid IEM that combines a 10mm dynamic driver, four balanced armatures, and eight electrostatic drivers per side for a detailed, multi-layered sound. Its titanium shell and five-way crossover aim to deliver a refined, high-resolution listening experience, while the included 4.4mm balanced cable offers versatility for audiophile setups.

  • Pro:Precision-milled titanium shell for durability and resonance control
  • Pro:Hybrid driver array (1DD + 4BA + 8EST) offers expansive treble and dynamic bass
  • Pro:Swappable plugs on the cable provide flexible connectivity
  • Con:No active noise cancellation, requiring a quiet environment or isolation tips
  • Con:High price point may limit accessibility
  • Con:16-ohm impedance may need a powerful source for optimal performance
