We developed the Ultimate Ears 18 Pro Custom In-Ear Monitors specifically for the most discerning performers and music listeners. If you demand nothing but the best, our flagship in-ear monitors deliver the comfort, quality, and sound that you expect. They combine our new experience-driven, six-speaker Ultimate Ears sound signature with new technologies including a new cable built for durability and reduced distortion, three acoustically tuned sound channels, and multiple passive crossover points creating the ultimate in separation, detail, and clarity. 

The Ultimate Ears 18 Pro is available with the optional ambient feature to allow for stage bleed while controlling the isolation effect.
