Thanks to Moshi Audio's RigidBody driver housing, the Moshi Vortex in-ear headphones deliver fast articulate bass without the distortion often present in ear bud designs. Consisting of Neodymium drivers housed in sintered steel alloy, the Moshi Vorex driver units minimize cavity-induced sound coloration. Thanks to this approach, the Vortex's improve the low frequency spectrum while providing clear and smooth highs.Other products from A4C
