Two wired hybrid IEMs sit close in price but take different paths to detail. The CrinEar Reference asks for $350 and a balanced source, while the Kiwi Ears Astral costs $299 and brings a bass-forward tilt. Both are wired, both rely on passive isolation, and neither has active noise cancelling. Here is how they stack up for critical listening and everyday use.
Price and positioning
The CrinEar Reference costs $350, and the Kiwi Ears Astral costs $299. That $51 gap is small in the wired IEM world, but it buys different things. The CrinEar uses a 2DD + 3BA hybrid driver setup and ships with a detachable 4.4mm balanced cable, which means you need a balanced source to get the full benefit. The Astral pairs a 10mm dynamic driver with six balanced armatures and runs on a standard 23 ohm impedance, so it is easier to drive from a phone or dongle. Neither is a budget pick, but the Astral is the more straightforward plug-and-play option.
The scores, side by side
HearWiki gives the CrinEar Reference a headline score of 86/100, and the Kiwi Ears Astral scores 82/100. That four-point gap is real but not dramatic; both are solid buys in the $300 range. The sub-scores tell a similar story. Sound is 9.1/10 for the CrinEar and 8.6/10 for the Astral. Value is 8.9/10 versus 8.3/10. The CrinEar leads on both, but the differences are within a point, so they are effectively a tie in terms of category strength. The headline score is not a weighted average of the sub-scores; it reflects overall buyability from published reviews and pricing.
Sound
The CrinEar Reference is described as balanced and detailed, with a hybrid driver setup that delivers rich, layered sound. It relies on a tight eartip seal for passive isolation, and its 16 ohm impedance pairs well with a balanced source. The Kiwi Ears Astral is bass-forward, with deep sub-bass and controlled punch, plus clear treble that avoids fatigue. It also offers strong instrument separation and resolution. The trade-off is that the Astral's mid-bass is somewhat reduced and lower mids can sound thin. If you want neutrality and layering, the CrinEar is the safer bet. If you prefer a warmer, more energetic tuning, the Astral has the edge. Both are hybrid IEMs, but they voice the drivers differently.
Noise cancelling and battery
Neither the CrinEar Reference nor the Kiwi Ears Astral has active noise cancelling. Both are wired IEMs, so there is no battery, no Bluetooth, and no codec support to compare. The CrinEar's passive isolation depends on getting a good seal with the eartips; the Astral's does too, though its large shells may make that seal harder to achieve for some listeners. The Astral has an IPX4 rating, which means it can handle splashes and sweat, while the CrinEar's IP rating is not listed. If you need noise cancelling or wireless freedom, look elsewhere, perhaps at the best ANC earbuds or the best true wireless roundups.
Calls and everyday use
Neither IEM is pitched as a calls product: there is no microphone on the spec sheet for either, and HearWiki gives neither a calls sub-score. Treat them as listening tools, not headsets. For everyday use, the CrinEar's 4.4mm balanced connector is a double-edged sword: it offers better channel separation with the right source, but it locks out standard 3.5mm outputs unless you use an adapter. The Astral's 23 ohm impedance is easier to drive, and its IPX4 rating adds some sweat resistance. Fit is a concern on both: the CrinEar can be finicky to seal, and the Astral's large shells may cause discomfort over long sessions. If you plan to wear them for hours, try both if you can, or check the best wired IEMs list for alternatives.
Which one should you buy?
Buy the CrinEar Reference if you already own a balanced source or are willing to invest in one, and you want a balanced, detailed sound for critical listening. Its higher score and slightly better value sub-score reflect that it does exactly what it sets out to do, provided you can get a good seal. Buy the Kiwi Ears Astral if you want a bass-forward sound with strong resolution at a lower price, and you prefer a standard output that works with any dongle. The Astral is the more forgiving everyday pick, but the CrinEar is the better tool for analytical listening.

FAQ
Are the CrinEar Reference and Kiwi Ears Astral good for gaming?
Both are wired IEMs without a microphone on the spec sheet, so they are not ideal for multiplayer comms unless you add a separate mic. Sound-wise, the CrinEar's balanced tuning and the Astral's bass boost can both work for gaming, but neither offers a dedicated gaming feature set. For a headset with a mic, see the best gaming headsets guide.
Do I need a balanced DAC for the CrinEar Reference?
Yes, the CrinEar Reference comes with a detachable 4.4mm balanced cable, so to use that cable you need a source with a 4.4mm balanced output. You can use an adapter to a standard 3.5mm jack, but you lose the balanced connection's benefits. The Kiwi Ears Astral uses a standard connection and does not require a balanced source.
Which IEM has better passive noise isolation?
Both rely on a tight eartip seal for passive isolation, and neither has active noise cancelling. The CrinEar Reference is noted for good passive isolation when the fit is right, while the Kiwi Ears Astral's large shells may make a consistent seal harder to achieve. Neither blocks noise as well as a dedicated ANC earbud, so if isolation is your priority, look at the best ANC earbuds instead.
