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

Both shipped in 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.

What reviewers said

Aful Explorer

The Aful Explorer is a compact hybrid IEM that prioritizes a warm, musical listening experience over raw technical performance. It pairs a solid low-end punch with smooth, easy-going treble, making it a comfortable and engaging choice for everyday listening at its price point. While its tuning and fit earn high marks, it falls short of class-leading detail retrieval.

Pro:Warm, musical tuning with satisfying bass
Pro:Comfortable, compact shell and good build quality
Pro:Smooth, non-fatiguing treble

Con:Detail retrieval is average for the class
Con:Timbre can sound slightly breathy or unusual
Con:Not a benchmark for technical performance

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
