The LETSHUOER Astralis is a wired IEM built around a 15.5mm fifth-generation ring-type planar driver in CNC-machined aluminum shells, with swappable 3.5mm and 4.4mm plugs and a DT01 Pro USB-C DAC cable in the box. It suits planar fans who move between a DAP, a dongle and a USB-C phone.
Who the LETSHUOER Astralis is for
Planar listeners: The 15.5mm ring-type planar replaces the usual square driver with a circular one, which LETSHUOER says brings deeper low-frequency extension and fast transient response.
USB-C phone users: The included DT01 Pro is a 3.5mm-to-USB-C DAC/amp cable, so the Astralis runs from a USB-C phone, tablet or laptop out of the box.
Balanced-source owners: Swap the 3.5mm plug for the 4.4mm plug on the same 216-strand cable to run balanced from a DAP or dongle.
Cable upgraders: Standard 0.78mm 2-pin sockets take common aftermarket IEM cables.
Skip it if: you need in-line controls or a 2.5mm plug; the cable has no remote and comes with 3.5mm and 4.4mm plugs only.
