Hear Music the Way It Was Meant to Be Heard

The CrinEar Reference is not just an in-ear monitor — it is a precision instrument. Engineered around a population-averaged diffuse field response tilted at -1dB per octave with a subtle bass lift for perceptual balance, it delivers one of the flattest, most accurate tunings ever achieved in an IEM. Fully verified under ITU-T Type 4.3 conditions, the Reference is the definitive choice for those who demand absolute sonic truth — whether in the studio, at the mixing desk, or in a dedicated listening room.

Uncompromised Accuracy. Extraordinary Clarity.

At the heart of the CrinEar Reference lies a sophisticated hybrid driver architecture — two 10mm dynamic drivers commanding the sub-bass with authority, paired with Sonion balanced armatures for transparent midrange reproduction, and a Knowles super tweeter extending the highs with effortless detail. The result is a full-range soundstage with exceptional separation, resolution, and coherence. Housed in a 5-axis CNC-machined full aluminum shell, every element is engineered to eliminate resonance and preserve acoustic integrity.

What sets the Reference apart:

- World-class flat frequency response for transparent, coloration-free listening

- Hybrid 2DD + 3BA driver system for full-spectrum precision

- Premium silver-plated copper cable with 3.5mm & 4.4mm interchangeable plugs

- 5-axis CNC aluminum housing for structural rigidity and acoustic stability

- Comprehensive eartip selection for a secure, comfortable, personalized fit

- Designed in Singapore for audiophiles, engineers, and studio professionals
