The latest from the acoustics team at Campfire Audio, Astrolith represents the tip-of-the-spear for IEMs using a pure planar magnetic architecture. Further expanding on Campfire’s lineage of planar earphones, Astrolith incorporates two new drivers wrapped in our PPR and AAOI tuning elements. Combining the inherent advantages of planar magnetic drivers with decades of acoustic engineering experiences brings about an incredible new horizon in the realm of planar magnetic IEMs.
