To heighten the hybrid listening experience, you have to curate the right drivers. Better yet: you can develop your own. In the MS4 IEM, Hidizs did both. To deliver smooth lows, subtle highs, and excellent all-frequency consistency, the company patented a new 10.2-millimeter dynamic driver with a macromolecular diaphragm just for the MS4. To complement it with extra articulation in mids and highs, they added a Knowles 33518 high-frequency balanced armature and a 30017 dual-composite balanced armature. Rounding out the MS4’s custom-tailored sound, a four-strand OFC silver-plated copper cable ensures pristine signal transmission with near-zero oxidation risk. Surrounding the drivers, CNC’d aluminum housings maximize durability, while resin shells optimize comfort in the ear.
