-: The Astral is Kiwi Ears professional-grade in-ear monitors designed to deliver a premium audio resolution and exceptional tonal balance. The Astral is intended for professional music engineers and discerning audiophiles who seek an engaging sound that does not compromise on accuracy nor precision..: The Astral utilizes an in-house 10mm bioceramic diaphragm dynamic driver. Our custom diaphragm material provides excellent thump in the low sub-bass frequencies that smoothly transition into a lush bass. The bass has been tuned to accommodate the unique characteristics of this driver, and features a slightly smoother transition from the bass into the mids, with a rolling cutoff at 300Hz..: The Astral utilizes in-house custom midrange balanced armature drivers to focus on a neutral midrange to make vocals and instruments sound tonally correct, with an accurate pinna compensation curvature at 2.8 kHz to perfectly match the perceived hearing of the human ear. This makes for a faithful reproduction of the sound similar to studio monitors.
