essonio ES-C19
A 5-driver Knowles balanced armature array delivers a neutral, reference-grade signature with precise instrument separation across a 5Hz-50kHz range. Each pair features a unique hand-painted faceplate on a 3D-printed shell and includes an 8-strand silver-plated 4.4mm balanced cable for superior channel separation. These IEMs are best for studio engineers and musicians requiring clinical vocal clarity and zero-latency monitoring during mixing or stage performances.
