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
CrinEar Nightfall (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.

What reviewers said
CrinEar Nightfall
The Nightfall is a wired, hybrid dual-driver in-ear monitor with a 10mm dynamic driver and an 8mm bass control unit, housed in a compact aluminum body. It delivers a balanced, natural sound with a warm lean, making it a versatile choice for casual listening at around $100. Its low 9-ohm impedance and 4.4mm balanced connector suit it for use with high-quality sources, though it lacks active noise cancellation.
- Pro:Warm, balanced tuning that suits many genres
- Pro:Compact and lightweight aluminum build
- Pro:4.4mm balanced output for enhanced channel separation
- Con:No noise cancellation, so isolation depends on fit

- Pro:Rich lower mids and airy treble
- Pro:Comfortable fit for long sessions
- Con:Sub-bass can feel a bit overpowering at times
