Our proprietary new 4-speaker system is designed specially for bassist, drummers, electronic producers, and any other musician that needs emphasized bass response. Using Knowles state-of-the-art Balanced Armature Drivers (informational video below) for unparalleled sound quality. This means that there are two separate Bass, one Mids, one Highs drivers with integrated crossovers in each ear making a staggering total of 8 drivers in each set. In-Ear Monitors give you the ability to hear yourself and your band perfectly at the levels you want. In addition our IEMs give you 25 dB outside sound isolation, protecting your hearing from the often dangerously loud on-stage sound.
