About the LETSHUOER Astralis
From the product page on linsoul.com.
The LETSHUOER Astralis features a proprietary 15.5mm 5th-generation ring-type planar diaphragm driver. It utilizes a circular planar diaphragm with a ring-shaped nanometer-grade magnetron-sputtered dual-sided voice coil, paired with a PTR elastic film surround. This architecture reduces cone break-up and distortion, while the double-sided voice coil configuration lowers the resonance frequency and enables a faster transient response. The result is a lush, dynamic sound with powerful bass, stable driver performance, and a wider soundstage compared to conventional planar drivers.
The driver is driven by a 4+4 ring-shaped fully symmetrical N52 high-performance magnet arrangement. This optimized magnetic circuit improves efficiency and bass response, working in tandem with the ring-type voice coil wiring to deliver a clean and accurate reproduction across the full frequency range. The 15.5mm round flat diaphragm ensures a coherent and detailed presentation, capturing the finest nuances in the recording.
The earpieces are housed in an ergonomic aluminum alloy chassis, finished in Lunar Silver Grey. The lightweight construction and carefully contoured shape provide featherlight comfort and refined elegance, allowing for long listening sessions without fatigue. The solid alloy build is designed to last.
