Siren: A Symphony of Craftsmanship and Sound As night falls, the Siren perches on moonlit rocks, her melodious voice soothing the sea, smoothing away worries and restoring tranquility. OA’s "Siren" earphones embody this calming essence with their handcrafted flowing sand design, inspired by the sea’s serenity. The delicate fishtail patterns, high-transparency imported resin, and fresh Tiffany Blue hue capture the beauty of water in motion. Like droplets reflecting the moonlight, the transparent casing enhances brightness and vibrancy. With crystal-clear sound and exquisite craftsmanship, the "Siren" brings a peaceful ocean to your ears in a noisy world. Hybrid Driver Configuration for Superior Sound With extensive experience in hybrid earphone design, we have crafted the "Siren" to fully maximize the unique characteristics of each driver. The "Siren" features a combination of 1 dynamic driver and 2 custom-tuned balanced armature drivers per side, supported by a 2-channel 3-way crossover system and a flexible low-frequency duct. This precise configuration ensures smooth transitions across low, mid, and high frequencies, allowing each range to shine. The BA drivers, specifically tuned for mid and high frequencies, deliver rich tones, enhanced clarity, and seamless phase alignment for a harmonious and natural listening experience. All-New Dynamic Driver with Metal Chamber Design The "Siren" is equipped with the same 2nd-Gen 10MM PU soft suspension long-stroke beryllium-coated diaphragm dynamic driver found in the "MIZAR", offering enhanced magnetic flux for superior kinetic energy efficiency. The beryllium coating strengthens the driver for more detailed, accurate sound reproduction, providing a richer and more nuanced listening experience. The flexible low-frequency duct further enhances bass depth and volume. Additionally, an independent front and rear metal chamber maximizes ample pneumatic volume and controls linear diaphragm response, effectively reducing resonances to deliver exceptional low-frequency performance. High-Quality OCC Interchangeable Plug Cable The "Siren" features a premium 0.78mm OCC cable with a shielding layer for added durability. This cable supports easy switching between 3.5mm single-ended and 4.4mm balanced plugs, with precise tuning and specially formulated solder to minimize any impact on sound quality. The standard 0.78mm 2-pin connectors are stable, reliable, and highly compatible for easy replacement. Additionally, the cable’s outer sheath is carefully color-matched to complement the earphone’s design perfectly. Harmonizing Science and Art in Tuning When tuning the "Siren," we referred to the Harman IE (2019) target curve but went beyond simply replicating it. Instead, we took a multi-dimensional approach, considering real-world listening impressions, user preferences, market trends, and the characteristics of popular music. While frequency curves and data provide a foundation, the final sound quality was refined through extensive listening tests, blending science and artistry. The result is a passionate, invigorating sound with a naturally expansive soundstage, full and sweet vocals, and powerful, resonant bass. Whether in dynamic music passages or subtle vocal details, the "Siren" offers a seamless, immersive experience—ideal for both professional monitoring and personal enjoyment. Ergonomic Design and Enhanced Comfort The "Siren" combines years of custom IEM expertise with a semi-custom shell design for lasting comfort, whether for daily use or extended listening sessions. It comes with two ear tip options, including the new OA05 liquid silicone tips, made from premium, skin-friendly, food-grade material, ensuring a hypoallergenic experience for users. These tips enhance passive noise isolation and improve vocal clarity, delivering a fuller, richer sound and a smoother, more immersive soundstage.
