2DD+2BA+4EST, MOONDROP Solis 2!

by C G on Jul 21, 2023

MOONDROP, as a matured audio manufacturer, provides numerous successful offerings, covering budget-oriented items to high-end catalogs, like Solis, their first electrostatic hybrid flagship IEM. Today, MOONDROP takes a big step toward the higher-end headphone industry and gives a full upgrade to Solis to announce Solis 2! Keep reading!

The whole housing of Solis 2 is made of 925 silver, and the feather-like texture is carved by jewelers. The logo of the "Golden Sun Bird", a national treasure symbol of the ancient Shu civilization, is hand soldered to the faceplate by 24K gold and silver-plating.

In terms of its driver configuration, Solis 2 features 2DD+2BA+4EST, and it was designed with sound quality optimization as the top priority. It achieves this goal with a meticulous choice of compatible drivers. Excellent mid-bass density and superb bass dynamics are delivered through specially designed dual dynamic-driver bass modules. The balanced armature is used solely to reinforce the mid-treble in generating soundstage depth, and the four Sonion high-dynamic electrostatic drivers provide exceptionally clear treble detail.

The new scientifically designed horizontally opposed double dynamic driver module further demonstrates the advantages of the hybrid earphone in bass dynamics.

HODDDUS (Horizontally Opposed Dual Dynamic Drivers Unit System) uses dual 10mm dynamic drivers arranged closely and symmetrically using 3D-printed modular components. The components form a physical band-pass filter comprising two independent filtering structures and damping devices, thereby facilitating acoustic adjustment.

The symmetrical HODDDUS arrangement focuses the magnetic field at the magnetic gap of the two dynamic drivers, leveraging the same principle found in planar magnetic earphones. This not only improves energy conversion efficiency but also further reduces nonlinear distortion.      

Each of the dual dynamic drivers consists of a flexible suspension diaphragm with a paper dome, and the high damping characteristics of the paper dome ensure that the dynamic driver does not generate additional resonance due to split vibration in the mids and highs, thus offering a smooth and natural timbre.

Supported by MOONDROP’s unparalleled acoustic R&D team, software, and hardware, ensuring high full-band phase consistency under the complex triple multiple drivers, and fully avoiding the abnormal soundstage and timbre caused by the frequency division connection problem on most triple headphones.

Solis 2 has a universal 0.78 2pin interchangeable cable, allowing users to replace the cable or accessories (such as MOONDROP Littlewhite Bluetooth Neckband) to expand the playability.

In order to give full play to the superior sound quality of Solis 2, the newly designed and developed PURE6 cable with chip-level high-purity copper is used.

The PURE6 cable adopts high-purity copper raw materials provided by material refiners who provide high-purity copper targets materials for well-known chip manufacturers and is handed over to the chip packaging and bonding manufacturer for vacuum wire drawing, so that the cable core creates a performance closer to the conductor theoretical value and higher conductive quality. On this basis, the parallel shielding structure is specially designed to further reduce signal loss and bring purer signal transmission quality.

In addition to the solid building, Solis 2 creates an extraordinary listening experience by delivering fine detail, rich timbre, full density, and powerful dynamics. As a super flagship IEM, Solis 2 is worth a try! As always, any suggestions, comments, and feedback are welcome, live chat with us or email support@shenzhenaudio.com for any support you want.
