MOONDROP Solis II 2DD+2BA+4EST Tribrid In-Ear Monitors

MOONDROP’s Flagship Tribrid IEM

The MOONDROP Solis II represents an uncompromising approach to high-end in-ear monitor design, combining three different driver technologies into a sophisticated eight-driver configuration.

Each earpiece incorporates two 10mm dynamic drivers, two balanced armature drivers, and four electrostatic drivers, carefully integrated through a three-way crossover. The result is an IEM designed to deliver exceptional bass authority, natural and richly textured midrange reproduction, and highly resolving treble.

2DD + 2BA + 4EST Tribrid Architecture

Solis II combines the strengths of three distinct driver technologies.

The two 10mm dynamic drivers provide the foundation for powerful, dense and highly dynamic bass, while the two balanced armatures reinforce the midrange and upper frequencies. Four electrostatic drivers extend the high frequencies with exceptional speed, delicacy and detail.

This carefully integrated driver configuration gives Solis II the ability to reproduce music with a combination of rich timbre, fine detail, full-bodied dynamics and an expansive sense of space.

Horizontally-Opposed Dual Dynamic Driver System

MOONDROP’s innovative Horizontally Opposed Dual Dynamic Driver Unit System (H.O.D.D.D.U.S.) is at the heart of Solis II’s low-frequency architecture.

The two dynamic drivers are arranged in a horizontally opposed configuration, allowing them to work together to produce powerful bass dynamics while helping control nonlinear distortion.

This architecture is designed to deliver greater low-frequency density and physical impact without allowing the bass to overwhelm the rest of the frequency range.

Highly Consistent Full-Band Phase

Managing multiple driver types in a complex hybrid IEM presents significant acoustic challenges. MOONDROP has developed the Solis II’s acoustic architecture and three-way crossover to maintain highly consistent phase characteristics across the full frequency range.

The carefully optimized acoustic design is intended to ensure that the individual drivers integrate naturally rather than sounding like separate components.

The result is a cohesive presentation with natural timbre, accurate imaging, and a spacious, open character.

Handcrafted 925 Silver Cavities

Solis II features exceptionally distinctive handcrafted 925 silver housings.

The silver cavities are finished with an intricate feather-like texture, combining traditional craftsmanship with MOONDROP’s modern acoustic engineering. The result is an IEM that is as visually distinctive as it is technically sophisticated.

The housings are further adorned with a finely crafted Golden Sun Bird motif, adding an elegant finishing touch to the flagship design.

Premium PURE6 High-Purity Copper Cable

Solis II is supplied with MOONDROP’s premium PURE6 high-purity copper cable, designed to provide exceptionally clean signal transmission.

The cable uses high-purity copper material and a carefully engineered parallel shielding structure designed to minimize signal loss and preserve the integrity of the audio signal.

The cable connects to the IEMs using a universal 0.78mm 2-pin interface, providing the flexibility to replace or upgrade the cable in the future.

Versatile Modular Connections

The included cable system is designed for flexibility, with the supplied accessory package including an OE adapter system supporting 2.5mm, 3.5mm and 4.4mm connections.

This allows Solis II to be used with a wide range of portable digital audio players, DAC/amps, headphone amplifiers and other high-quality audio sources.

Designed for Serious Audiophile Listening

With its sophisticated eight-driver architecture, innovative dual-dynamic bass system, electrostatic treble drivers, handcrafted silver housings and premium cable, Solis II is designed for listeners who demand the highest level of performance from an in-ear monitor.

It combines technical precision with a rich, natural musical presentation, making it an exceptional choice for critical listening and high-end portable audio.
