The World’s Flattest In-Ear Monitors.

Purpose-built for absolute neutrality, the CrinEar Reference is a precision-engineered in-ear monitor designed to deliver true reference-grade sound. Tuned to a −1.0 dB/octave population-averaged diffuse field target and verified under ITU-T Type 4.3 conditions, the Reference achieves exceptional tonal accuracy, balance, and transparency; making it ideal for critical listening, studio monitoring, and mix evaluation. 

At its core is a 2DD + 3BA hybrid driver system, featuring a Horizontally-Opposed Dual Woofer System (HODWS) for clean, controlled bass with reduced distortion, paired with balanced armatures for precise midrange and extended treble detail. A 5-axis CNC-machined aluminium shell offers durability, acoustic stability, and a contoured pseudo-custom fit for long-term comfort. 

A benchmark for a new age. The Reference.
