- Crystal-Infused Diaphragm Structure, Pristine and Profound] The W-shaped crystal-infused composite diaphragm is crafted using a specialized process. The silicon-based crystalline structure offers exceptional rigidity and transparent high frequencies. The independent flexible surround complements the diaphragm for deeper, punchier lows. From crystalline overtones to deep rhythms, the IR300 faithfully reproduces the brilliance and weight of sound. Rich, nuanced, and naturally layered.
- [Symmetric Motor System, Stable Dynamics] An optimized symmetric motor system ensures even magnetic field distribution and high energy conversion efficiency, further enhancing driver control and transient response. Even in complex dynamic passages, sound remains clean, powerful, and effortlessly composed.
- [3×2 Tuning Configurations, Master Every Sound] Featuring 3 kinds of nozzles and 2 kinds of chamber tuning modules - all purely physical acoustic designs that avoid the added coloration of electronic processing, delivering a more authentic and natural listening experience. 3 × 2 = 6 distinct tonal profiles, offering plenty of room for exploring different musical styles: Nozzles: Golden nozzle: neutral and versatile—an all-rounder in tone; Black nozzle: smooth and pleasant—warm vocal character; Silver nozzle: bright and clear—lively instrumental presence. Chamber tuning modules: Vented module: powerful bass with rich texture; Sealed module: tight bass with layered precision.
- [Precision Acoustic Chamber, Enduring Sound Quality] The IR300 utilizes a high-strength metal chamber, precision-crafted via CNC machining. Its robust shell effectively suppresses unwanted resonance and deformation, providing a stable acoustic environment for the driver. Inside, multiple damping elements and a precision-coupled structure further refine the sound transmission path. This ensures the audio reproduction remains accurate and consistent over long-term use.
- [Hypoallergenic Ear Tips, A Boon for Sensitive Skin] The package includes two sets (seven pairs in total) of specially treated ear tips, particularly friendly for users with sensitive skin and an ideal choice for those with oily ears. The soft silicone material fits snugly in the ear canal, ensuring stability and comfort even during prolonged wear.
- [Interchangeable Plug Cable, Versatile for Multiple Scenarios] The high-spec interchangeable plug cable with high-purity oxygen-free copper conductors and a Litz braided structure ensures pure and smooth signal transmission. The modular plug design allows effortless switching between single-ended 3.5 mm and balanced 4.4 mm connections, offering robust durability to meet diverse listening needs.
- [Reference-Grade Tuning, Sound Tailored to Your Preference] Continuing the Reference series’ philosophy of balanced tuning, the IR300 delivers solid, reliable control over both linear and nonlinear distortion. Whether you seek pure reference accuracy or personalized tuning, the IR300 delivers natural, smooth frequency response and rich, detailed nuances—placing every shade of sound at your command.
