Meticulously tuned 14.5mm planar driver 

The Moondrop Stellaris uses a 14.5 planar magnetic driver with excellent nonlinear distortion performance. Moondrop carefully modified the acoustic structure of the Stellaris by attaching an independent built-in acoustic cavity to accurately control the resonant frequency of the system.

High-precision miniature magnet array

The fully-symmetrical magnetic circuit is composed of 7+7 N52H magnets, precisely arrayed during mold assembly to deliver lower harmonic distortion and higher magnetic circuit efficiency. They produce a maximum magnetic flux at the magnetic gap close to 1 Tesla, resulting in clearer sound quality.

Sub-nanometer diaphragm

The driver of the STELLARIS utilizes a sub-nanometer diaphragm with a thickness of 1um, stretched tightly on the bracket at uniform tension. This high-precision, ultra-thin, uniformly stressed diaphragm structure can deliver lower split vibration and nonlinear distortion in the vibration process, and ultimately generate a more transparent timbre with clearer details.

Iridescent shell

The shell of the STELLARIS uses the same iridescent finish as the Starfield, reflecting different colors under different light conditions. The golden hand-painted pattern is emblematic of the starry theme of STELLARIS.
