The U4s is a universal-fit, four-driver hybrid in-ear monitor with an anodized aluminum shell. Its driver array combines one dynamic driver for low frequencies, two balanced-armature drivers for low-mid and high-mid frequencies, and a tia balanced-armature driver for high frequencies. It uses 64 Audio’s tia, LID (Linear Impedance Design), and apex pressure-relief technologies, along with an integrated four-way passive crossover and an electrical low-pass filter. Interchangeable apex modules provide different isolation levels.
