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 Astral is 6 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 6 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said

Etymotic ER2XR

The Etymotic ER2XR is a wired dynamic-driver IEM that offers a neutral-to-slightly-warm sound signature with a moderate bass boost, while maintaining the brand's signature deep isolation and technical clarity. It delivers clean, detailed, and natural audio performance that stands out in the sub-$200 range, wrapped in a featherlight design with a solid accessory bundle. Its high impedance and low sensitivity mean it benefits from a dedicated amplifier to reach its full potential.

Pro:Balanced, mildly warm tuning with a subtle bass lift
Pro:Excellent isolation and technical detail for the price
Pro:Very light and comfortable fit

Con:Requires a capable source due to low sensitivity
Con:Thin note texture may not suit bass-heavy listeners
Con:Deep insertion fit is not for everyone

Kiwi Ears Astral

The Kiwi Ears Astral is a hybrid wired IEM that blends a dynamic driver with six balanced armatures, delivering a bass-forward yet detailed sound with smooth highs and a natural midrange. While it offers strong clarity, good instrument separation, and a comfortable fit for many, its large shells may cause fatigue over long sessions, and the mid-bass and lower midrange could feel leaner than some listeners prefer. Overall, it's a well-rounded performer in the $300 range, though not perfectly neutral due to its elevated low end and relaxed treble.

Pro:Deep, impactful sub-bass with good control
Pro:Clear and detailed treble without harshness
Pro:Natural midrange with good instrument separation

Con:Large shells may reduce comfort during extended listening
Con:Limited included eartip selection
Con:Mid-bass punch and lower midrange can seem thin
