What reviewers said
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
Noble Audio Vanguard and Iris
Noble Audio's new universal IEMs offer two distinct tuning approaches: the Vanguard is a budget-friendly three-driver hybrid that blends a 10mm PEK dynamic driver with dual balanced armatures, while the Iris steps up as a pricier single-dynamic-driver model with a 10.2mm driver. Both wired designs feature USB-C connectivity and are geared toward listeners who prefer either hybrid versatility or the coherence of a single-driver sound.
- Pro:Affordable hybrid option with dual-armature detail
- Pro:Lightweight and portable wired design with USB-C
- Pro:Balanced impedance and high sensitivity for easy driving
- Con:Iris price is significantly higher for a single-driver setup
- Con:Limited frequency range compared to some rivals
- Con:No wireless or ANC features for on-the-go use
