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 Kiwi Ears KE4 is 3 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 3 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said

Kiwi Ears KE4

The Kiwi Ears KE4 is a wired hybrid IEM that offers a balanced, relaxing sound with a distinct twist on the popular 'New Meta' tuning, adding extra bass and treble sparkle. It delivers solid midrange clarity and a comfortable fit, making it a versatile choice for many genres, though its smooth presentation may not excite those seeking aggressive or highly dynamic sound.

  • Pro:Well-balanced hybrid tuning with rich lower mids and airy treble
  • Pro:Comfortable fit and broad genre versatility
  • Pro:Good resolution and clarity for its price
  • Con:Sub-bass can get overpowering at times
  • Con:Limited resolving power and dynamic impact
  • Con:Smooth tuning may feel less exciting than V-shaped alternatives

Moondrop KATO

The Moondrop KATO is a single 10mm dynamic driver IEM with a DLC diaphragm, offering a balanced and smooth tonal presentation that appeals to listeners seeking refinement over aggressive tuning. It is easy to drive thanks to its 32-ohm impedance and high sensitivity, and it comes with a generous accessory set that adds to its value. While it impresses with its cohesive sound and wide soundstage, it may lack impact in the low end and can occasionally sound sharp or fatiguing to some ears.

  • Pro:Balanced and smooth tuning
  • Pro:Easy to drive with any source
  • Pro:Wide soundstage
  • Con:Lacks low-end slam and impact
  • Con:Can sound sharp or fatiguing at times
  • Con:Not the most technically resolving option
