The World’s Flattest In-Ear Monitor.

US$349.99

Absolute Neutrality

The CrinEar Reference is a purpose-built in-ear monitor engineered to achieve extreme tonal accuracy. Developed through bleeding-edge acoustic research, Reference is designed to be the world’s flattest-measuring IEMs available*, prioritizing transparency, linearity, and repeatable accuracy.

*Based on adherence to population-averaged diffuse field response (JM-1) with a -1dB/octave tilt, measured on ITU-T P.57 Type 4.3 standard equipment

Tuned for the studio

Built for the stage

The CrinEar Reference is engineered as a true monitoring tool, delivering realistic, true-to-source playback for critical listening and mix evaluation.

Providing reliable tonal balance, precise midrange clarity, and controlled low-frequency response, the Reference aims to be your portable studio monitor, allowing mixes to translate with confidence beyond any room.

HODWS architecture

Bass frequencies are handled by a custom-built system utilising twin 10mm dynamic drivers, arranged in a horizontally-opposed configuration. This Horizontally-Opposed Dual Woofer System (HODWS) allows the two woofers to share their mechanical load, resulting in:

  • Reduced stress in each diaphragm

  • Improved bass linearity and control

  • Improved power efficiency

  • Stronger and tighter bass response

Ultimately ensuring realistic bass response out of a flat tuning. Because “flat bass” shouldn’t mean “no bass”.

Sonion & Knowles Ba Drivers

Midrange and high frequencies are reproduced by a carefully-constructed array of twin Sonion midrange drivers and a single Knowles supertweeter. Every driver is hand-selected to achieve our stringent tuning goals, and subsequently designed with the most efficient crossover network possible.

CNC-Machined Aluminium Shell

All of the Reference’s drivers are housed in a full aluminium metal shell, precision-machined using a 5-axis CNC process. The contoured pseudo-custom geometry provides:

  • High structural rigidity to suppress enclosure resonance

  • Long-term durability capable of enduring professional use

  • Secure, comfortable fit optimized for extended sessions

Premium Modular Cable

A premium detachable cable is included, featuring an interchangeable termination system:

  • 3.5mm single-ended for universal compatibility

  • 4.4mm balanced for lower crosstalk and improved channel separation

Enjoy flexibility across portable and desktop sources, consumer and professional, without sacrificing signal quality.
