Features & Specs
Dual planar magnetic drivers for full-spectrum planar performance
Fast, deep bass with rich midrange from the 14.2mm driver
Comes with both 3.5mm and 4.4mm MMCX cables
Wide 5Hz–25kHz frequency response for lifelike sound
Expert Insight
The Astrolith completely changed how I experience my music. The detail is unmatched, the soundstage is wide, and the bass is surprisingly tight for a planar IEM. It’s both technically impressive and emotionally engaging — easily one of the best IEMs I’ve used.
