The Westone ES50 represents the culmination of everything Westone has learned about in-ear monitor technology since they brought their first custom monitors to market in 1996. The ES50’s purity of sound penetrates your entire being; the five masterfully tuned balanced armature drivers satisfy even the most critical ear. Designed for the on-stage musician or the serious audiophile, the proprietary flex-canal body provides the user the most comfortable in-ear monitor on the market today.
