CrinEar Reference | Hybrid Universal IEMs

Designed to Be the World's Flattest-Measuring IEMs, Reference by CrinEar Boasts Ultimate Tonal Accuracy Coming soon! Driver Configuration: (2x) DD + (3x) BA True-to-Source Playback for Analytical Listening Features Sonion and Knowles Balanced Armature Drivers Full Aluminum Metal Shell for Durability Includes Premium Modular Cable with 3.5mm + 4.4mm Plugs 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. 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 and 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. Durable and Sleek Housing 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 listening sessions Modular Cable A premium Silver-plated Copper detachable cable is included, featuring an interchangeable termination system. The 3.5mm single-ended plug is for universal compatibility, while the 4.4mm balanced plug is intended for lower crosstalk and improved channel separation.  Enjoy flexibility across portable and desktop sources, consumer and professional, without sacrificing signal quality.
