Background and Identification
The Reference is CrinEar's second production model IEM, launched in April 2026.
The Reference takes its name from being tonally accurate to the Population-Averaged Diffuse-Field JM-1 target, with a -1 dB/octave tilt to recreate some tonal balance of loudspeakers in a listening room in contrast to an anechoic chamber and a 2 dB bass lift for a flatter perceived balance. The model was tuned on an ITU-T P.57 Type 4.3 ear simulator.
The Reference has a CNC-machined aluminum shell.
