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
Both shipped in 2026. 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 Project Monolith
The CrinEar Project Monolith is a limited-edition wired IEM engineered for bass enthusiasts, pairing a hybrid dual-driver setup with a brass build to deliver powerful low-end while keeping mids and highs natural. Its niche, bass-forward tuning and 999-unit production run make it a collector's piece rather than an all-rounder, though comfort is a standout strength. With a 4.4mm balanced connection and a wide frequency range, it targets listeners who prioritize sub-bass impact over neutrality.
- Pro:Deep, punchy bass with natural mids and highs
- Pro:Comfortable fit despite the bass-heavy tuning
- Pro:Innovative brass construction and driver co-design
- Con:Extreme bass tuning may overwhelm clarity for some
- Con:Limited 999-unit run restricts availability
- Con:Requires a balanced 4.4mm source for best use
CrinEar Reference
The CrinEar Reference is a wired in-ear monitor with a hybrid 2DD + 3BA driver setup, offering a balanced and detailed sound signature. It features a detachable 4.4mm balanced cable and relies on a tight seal for passive isolation, making it a strong choice for critical listening at its price point.
- Pro:Hybrid driver configuration delivers rich, layered sound
- Pro:Detachable 4.4mm balanced cable for flexible connectivity
- Pro:Good passive isolation from proper eartip seal
- Con:No active noise cancellation, so external noise isn't fully blocked
- Con:Requires a balanced source to fully utilize the 4.4mm connector
- Con:Fit may be finicky for some users to achieve optimal seal
