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 8 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 8 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said
Etymotic ER4SR Earphones
The ER4SR is a wired, single balanced-armature in-ear monitor built for critical listening, delivering an exceptionally flat and accurate response that suits studio work and audiophile purists.

With a detachable MMCX cable and multiple ear tips, it offers flexibility for those who prioritize fidelity over everyday usability.

- Pro:Excellent midrange detail and informative sound
- Pro:Strong passive noise isolation due to deep fit
- Con:Limited bass impact and roll-off at high frequencies
