METICULOUSLY TUNED 14.5mm PLANAR DRIVER WITH EXCELLENT SOUND QUALITY

A planar driver is a kind of transducer in which efficiency is traded for bandwidth. Its application in in-ear headphones is far less common than in full-size headphones, but its special timbre has attracted much favorable attention.

We decided to apply this architecture to our existing Starfield line, and create a planar in-ear headphone with excellent performance and a cost-effective price tag.

From among the many planar drivers on the market, we selected an outstanding driver with excellent nonlinear distortion performance and consistency, and exchanged higher cost for more stable sound quality and lower distortion.

With this in mind, the acoustic structure of the driver has been carefully modified, and by attaching an independent built-in acoustic cavity to accurately control the resonant frequency of the system, linear distortion performance has been optimized, creating a more natural timbre.

COLLABORATION WITH THE PIONEER OF MINIATURE PLANAR DRIVERS

Tuoyin Electronics Co., Ltd. is the first manufacturer in China to design and develop planar drivers for in-ear headphones. It has an outstanding record in the design and manufacture of miniature planar drivers, and owns many international patents. The 14.5mm planar driver, the result of its excellent miniature planar driver production QC and advanced technology, features far superior nonlinear distortion performance, acoustic consistency and product reliability

Leveraging MOONDROP's rich experience and know-how in acoustic structure design and earphone tuning, we carried out precise modification of the acoustic structure of this driver, and combined it with cavity adjustment to achieve exceptional sound quality performance.

HIGH-PRECISION MINIATURE GRID MAGNET ARRAY

7+7 N52H MAGNETS
FULLY SYMMETRICAL MAGNETIC CIRCUITS

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

SUB-NANOMETER DIAPHRAGM

1 UM SUB-NANOMETER DIAPHRAGM
2 UM ETCHING CIRCUIT

The driver of the STELLARIS utilizes a sub-nanometer diaphragm with a thickness of 1um, stretched tightly on the bracket at uniform tension. The vibration of the diaphragm generates ampere power to drive vibration and sound through a snake-shaped etched circuit with an accuracy of up to 2um and a magnetic field parallel to the diaphragm. This high-precision, ultra-thin, uniformly stressed diaphragm structure can deliver lower split vibration and nonlinear distortion in the vibration process, and generate a more transparent and melodious timbre with clearer details

INHERITING THE STARFIELD'S IRIDESCENT SHELL

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

COMES WITH TWO KINDS OF EAR-TIPS

MIS-TIP &
U.C.TIP HIGH LIQUID PERMEABILITY SILICONE EAR-TIPS

U.C. Ear-tips (Ultra Clear Tip), newly developed by Softears, are made of high-permeability liquid silicone. Based on ergonomic design, they fit far more snuggly in the ear canal than ordinary silicone ear-tips, ensuring lossless sound quality of bass under pressure, improved bass performance without any bleeding into the treble, and all-round improvement,

MARKET-LEADING SOUND PERFORMANCE

Relying on the excellent nonlinear distortion of the 14.5mm driver and the time-proven acoustic tuning of the shell, STELLARIS has an excellent acoustic performance index that lifts it above most planar in-ear headphones. The performance is not only comparable to flagship dynamic driver earphones in terms of nonlinear distortion, but also has a frequency response performance that is highly consistent with the VDSF Target Response based on HRTF and optimized for listening characteristics. The result is more accurate sound reproduction with richer, more natural details.

The MOONROP VDSF Target Response is a parametric target and sound quality is controlled by composite elements, thus restoring the sound quality to mastering levels, and creating an open soundstage with the characteristics of a diffusion-tuned space.
