ROSESELSA QuietSea II - HiFi & Gaming In-Ear Monitors Mercury / Moon Blue

One IEM, Two Ways to Listen

The ROSESELSA QuietSea II brings music listening and competitive gaming together in a lightweight, single dynamic driver in-ear monitor. Its 10mm driver, carbon-copper alloy dome diaphragm, and hybrid shell are designed to deliver rich textures, spacious sound, and impactful bass.

Move from a favorite playlist to an evening gaming session with an edition tailored to your setup. Choose the HiFi version for modular audio connections, or the Gaming Edition for an inline microphone and dedicated gaming sound card.

10mm Carbon-Copper Dome Driver

A dual-magnetic, dual-cavity dynamic driver combines a multilayer PEEK diaphragm with a vacuum-coated carbon-copper alloy dome. This structure supports fast transient response, low distortion, and extended sub-bass reproduction.

ORBITA Acoustic Architecture

The ORBITA acoustic system pairs a high-flux magnetic circuit with a large Japanese black voice coil, supporting efficient energy conversion, dynamic musical passages, and deep, punchy bass.

Precision Hybrid Shell

Five-axis CNC-machined aluminum alloy faceplates meet a semi-transparent polycarbonate mid-cavity. The combination creates a distinctive finish while offering a glimpse of the internal acoustic structure. Available colors are Mercury and Moon Blue.

Choose Your Edition

• HiFi: Includes the Jasmine 5N four-strand single-crystal copper modular cable with interchangeable 3.5mm single-ended and 4.4mm balanced plugs.
• Gaming Edition: Includes an inline microphone cable and RZ-200G gaming sound card. Physical controls enable virtual 7.1 surround processing to emphasize positional cues such as footsteps and gunshots in compatible games.

Accessory bundles differ by edition. Select the configuration that matches your audio source and intended use.

Lightweight, Low-Profile Comfort

Each earpiece weighs approximately 4.9g. An ergonomic shape informed by 3D ear-canal data uses a shallow-insertion design intended to reduce pressure during extended listening and gaming sessions. Comfort and fit vary by listener and ear-tip selection.
