Moondrop Variations Delivers an Evolution of Tribrid Technology at an Affordable Price The culmination of Moondrop's quest to deliver a powerful, comfortable and accessible Tribrid 1 DD, 2 BA, 2 EST and advanced crossover Blends the capabilities of each driver to deliver a cohesive sound and natural timbre Combines high quality acoustic materials, audio research, and state of the art electrical design Searching for Perfect Harmony in a Tribrid IEM Since the application of electrostatic driver for in-ear earphones, products with electrostatic units have emerged one after another, but they have been criticized for reasons such as "unaccept able tone" or "difficult to drive". The development of Variations adopts our previous experience in the development of EST + BA hybrid and EST + DD hybrid earphones. With 3D printing, a precise physical filter structure and frequency divider circuit are manu factured to produce excellent amplitude-frequency response and phase-frequency response. Conveys the perfect harmony of the sound and imaging. Ergonomic fit for the ear canal and Skin-friendly texture design Variations continues the ergonomic design of multi-unit composite earphones, which can fit the human ear canal comfortability. The cavity is made of medical resin 3D printing. Hand polished and finely sandblasted design for skin-friendly surface, which not only has an excellent texture, but also fits the ear canal more comfortably. It looks elegant when the fine sandblasting stainless steel panel fits with the frosted cavity. The bass driver adopts the newly developed 10mm liquid crystal diaphragm composite copper inner cavity diaphragm dynamic driver. The liquid crystal polymer liquid crystal polymer diaphragm with a thickness of only 9um has balanced compliance and domping. Dual balanced armature drivers are customized by Softears, which is not only transient and excellent in detail, but also exhibits amplitude-frequency characteristics that high meet the requirements of Variation design, which complements the DD and the EST drivers. The Variations treble driver adopts Sonion's new high-power version of one-to-two compound double electrostatic tweeter, which bring high-efficiency, dymanic, and excellent resolution to the high pitch. In order to achieve excellent frequency response and consistent phase across all frequencies, Variations inherited and improved the hybrid crossover design of Blessing2. Through the 3D printed precision acoustic channel combined with domping materials to achieve low-frequency physicol bond-pass filtering and medium-high-frequency low-pass smoothing filtering, coupled with accurate RC low-poss filter circuit, high- pass filter circuit and equalization circuit, Variations con show very ideal frequency response and phase indicators. Excellent Acoustic Performance through Masterful 3D Printing In order to accurately achieve the complex physical filtering intermal structure of Variations and avoid the acoustic structure error, an ultra high-precision 3D printing process is needed, so we cooperate with the well-known 3D printing supplier "HeyGears Technology" to apply its mature high-precision DLP 3D printing technology and use imported medical-grade UV resin to produce high precision, high transparency, high hardness, and accurate complex cavity. Advanced transducer unit and rigorous acoustic structure design, coupled with carefully polished physical filtering and crossover circuits, make Variations outstanding results in both linear and nonlinear distortions. Frequency Response is tuned based on MOONDROP VDSF Target Response (calculated by combining B&K HATS diffusion field HRTF and room reverberation curve) to bring a true and accurate longitudinal sound field and present the sound quality that can accurately restore the bring a true accurate longitudinal soundstage and an original restored sound timbre.
