Further expanding on Campfire’s lineage of planar earphones, Astrolith incorporates two new drivers wrapped in their 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.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Campfire Astrolith custom lithograph artwork highlighting earphones\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0023\/9255\/5595\/files\/campfire-astrolith.jpg?v=1721163238\"\u003e\u003c\/p\u003e\n\u003ch3\u003eAdvanced Acoustic Engineering\u003c\/h3\u003e\n\u003cp\u003eCampfire Audio designed several unique and new acoustic technologies specific for Astrolith's miniature Planar Magnetic drivers. The 6mm Planar Magnetic tweeter was a very special challenge for the CFA engineering team.
