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 4 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 4 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said

Final B2

The Final B2 is a wired in-ear monitor built around a single balanced armature driver, offering a straightforward and efficient listening experience. It pairs high sensitivity with easy drivability, making it a practical choice for use with phones or small portable players. While its sound is competent and well-defined for the price, the tuning leans conventional with modest top-end reach.

Pro:Efficient and easy to drive from portable sources
Pro:Clear, well-defined single-BA tuning
Pro:Lightweight and comfortable fit for long sessions

Con:Limited upper-treble extension
Con:Single-driver design lacks dynamic range
Con:Not a standout in a crowded price bracket

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
