The Astru’s housing is CNC-machined from a single block of solid titanium, then undergoes a multi-step electroplating process to achieve a satin finish. This monoblock construction enhances the shell’s rigidity and ensures its durability over time.
The 10 mm dynamic driver features a multilayer composite dome (80 thin layers of gold and a titanium coating on a PEEK diaphragm) for resolution comparable to a multi-driver configuration, with a sensitivity of 111 dB SPL/mW at 1 kHz and a frequency response ranging from 5 Hz to 35 kHz.
The 1.2-meter cable features two silver-plated LC-OFC copper strands, sheathed in SoftFlex PVC, terminated with a 2-pin connector and a 4.4 mm jack. A 4.4 mm female-to-3.5 mm male adapter is included to accommodate sources with a standard jack.
Five pairs of liquid silicone ear tips (XS, S, M, L, XL) are included to optimize fit and sound isolation. The set comes with a hard case and a PU leather sleeve for travel.
