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

Kefine Quatio (2025) against Kiwi Ears KE4 (2024). These are 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.

Kiwi Ears KE4

The Kiwi Ears KE4 is a hybrid IEM that delivers a balanced, smooth sound signature with a touch of added bass and treble sparkle, making it a versatile choice for many genres. It offers solid clarity and a comfortable fit, though its tuning leans relaxed rather than aggressive, and it lacks the ultimate resolving power of pricier models. Overall, it's a polished performer around the $200 mark that suits listeners who prefer a neutral yet slightly warm presentation.

  • Pro:Well-balanced tuning with a relaxing character
  • Pro:Rich lower mids and airy treble
  • Pro:Comfortable fit for long sessions
  • Con:Sub-bass can feel a bit overpowering at times
  • Con:Limited dynamics and resolving power compared to top-tier IEMs
  • Con:Accessories are minimal
