OASEAR SIREN (4.4mm)

OASEAR SIREN: A Symphony of Craftsmanship and Sound

Inspired by the tranquility of the ocean and the mythical Siren, the OASEAR Siren combines thoughtful acoustic engineering with distinctive craftsmanship. Its handcrafted flowing-sand faceplates feature delicate fishtail patterns, complemented by high-transparency resin shells and a refreshing Tiffany Blue finish. The design captures the movement and clarity of water, giving Siren an elegant appearance that reflects its smooth, immersive sound.

Hybrid Driver Configuration

The OASEAR Siren features a hybrid configuration consisting of one dynamic driver and two custom-tuned balanced armature drivers per side. A two-channel, three-way crossover system and flexible low-frequency duct help maintain smooth transitions between bass, midrange, and treble.

The balanced armature drivers are specifically tuned for the mid and high frequencies, contributing to clear vocals, detailed instrument reproduction, and a cohesive overall presentation. This combination allows Siren to deliver a balanced listening experience while preserving the distinct strengths of each driver type.

Second-Generation Dynamic Driver with Metal Chamber Design

Siren incorporates a second-generation 10mm dynamic driver featuring a PU soft-suspension, long-stroke beryllium-coated diaphragm, also found in the OASEAR MIZAR. The beryllium coating improves diaphragm rigidity, supporting more accurate movement and detailed sound reproduction.

An independent front and rear metal chamber design provides controlled airflow and helps minimize unwanted resonance. Together with the flexible low-frequency duct, this construction supports deeper bass extension, improved low-frequency control, and a fuller, more textured bass response.

Premium OCC Cable with Interchangeable Plugs

Siren comes equipped with a high-quality OCC cable featuring a protective shielding layer and interchangeable 3.5mm single-ended and 4.4mm balanced plugs. This allows for convenient compatibility with a variety of audio sources without requiring separate cables.

Standard 0.78mm 2-pin connectors provide a secure connection while allowing for easy cable replacement or upgrades. The cable's outer sheath is also color-matched to complement Siren's distinctive design.

A Balance of Science and Musicality

Siren's tuning takes inspiration from the Harman IE 2019 target curve while incorporating adjustments based on listening evaluations, musical preferences, and different genres.

Rather than focusing solely on frequency response measurements, its tuning emphasizes an enjoyable and natural presentation. The resulting sound offers a spacious soundstage, full-bodied vocals, energetic dynamics, and impactful bass, with enough clarity to bring out subtle details in recordings.

This balance makes Siren suitable for a wide range of music, from vocal-focused tracks to more dynamic and instrument-heavy recordings.

Ergonomic Design for Everyday Comfort

Drawing on OASEAR's experience with custom in-ear monitors, Siren features a semi-custom shell designed to provide a secure, comfortable fit during extended listening sessions.

Two ear tip options are included, one of which is the OA05 liquid silicone ear tip. Made from soft, skin-friendly, food-grade silicone, these tips are designed to improve comfort and passive noise isolation while supporting a fuller vocal presentation and smoother overall sound.

Combined with its lightweight resin construction and ergonomic contours, Siren offers a comfortable listening experience for both everyday use and longer listening sessions.
