OpenAudio Siren 1DD+2BA Hybrid Driver In-Ear Earphone IEM

1DD + 2BA Hybrid Driver Design

The Siren is equipped with a 10mm dynamic driver coated with beryllium for enhanced rigidity and a richer sound. Paired with two BA drivers, this earphone delivers balanced sound across the low, mid, and high frequencies, ensuring every detail is heard clearly.

2-Channel, 3-Way Crossover with Flexible Low-Frequency Duct

The Siren's advanced crossover system ensures smooth transitions between frequencies, allowing the bass to remain full and deep while maintaining a natural sound signature.

Unique Flowing Sand Texture Design

The Siren features a unique handcrafted flowing sand design that combines aesthetics with functionality. The high-transparency imported resin casing and intricate fish tail patterns evoke a sense of elegance and artistry, making these earphones as beautiful as they are functional.

OCC Twisted Cable with Interchangeable Plugs

The Siren includes a high-quality 1.2m 4-core twisted OCC (Ohno Continuous Cast) cable with a 0.78mm 2-pin connector. This cable supports flexible switching between 3.5mm single-ended and 4.4mm balanced plugs, ensuring compatibility with a wide range of devices.

Independent Dynamic Driver Metal Chamber

An independent front and rear metal chamber design for the dynamic driver enhances the low-frequency performance and ensures more accurate sound reproduction, with better control over diaphragm movement.

High-Frequency Precision with Dual Balanced Armatures

The mid and high frequencies are handled by two custom-designed BA drivers, providing enhanced clarity and detail in these ranges, ideal for vocal and instrumental listening.

Ergonomic and Comfortable Design

With years of experience in designing custom IEMs, OpenAudio has crafted the Siren with a semi-custom shell for a perfect fit, ensuring comfort during extended listening sessions. At just 44g, including the cable, these IEMs offer lightweight and comfortable wear.

Liquid Silicone Ear Tips for Optimal Comfort

The Siren includes the newly developed OA05 liquid silicone ear tips, made from skin-friendly, hypoallergenic materials. These ear tips provide a secure, comfortable fit while enhancing passive noise isolation and boosting vocal presence in the audio.
