• 【Hybrid Driver Technology for Immersive Sound】Equipped with a 12mm dual-cavity dynamic driver and a 11.6mm bone conduction unit, Winter Ultra delivers a rich, full-range sound. The dynamic driver enhances bass and midrange with air conduction, while the bone conduction unit refines treble clarity and expands the soundstage.
• 【Advanced Bone Conduction Treble Enhancement】Winter Ultra features a custom-developed bone conduction system that compensates high frequencies by transmitting sound through bone vibration. This reduces harshness often found in traditional treble tuning and ensures smooth, detailed highs with extended spatial depth.
• 【High-Performance Materials and Construction】Crafted from durable aluminum alloy using 5-axis CNC milling, the earphone shell offers superior durability and a refined, artistic design. The PAR diaphragm dynamic driver provides better elasticity and responsiveness compared to conventional diaphragms, improving sound resolution and dynamics.
• 【Upgraded Detachable Cable with Swappable Plugs】Includes a silver-plated single crystal copper cable with 0.78mm 2-pin connectors and swappable 3.5mm and 4.4mm plugs. This upgrade enhances signal clarity and ensures compatibility with a wide range of audio devices.
• 【Balanced Tuning with Vibrant Atmosphere】The Winter Ultra is tuned for a spacious and atmospheric sound signature. It delivers strong low-frequency impact, sweet and natural vocals, and a wide, layered soundstage—making it ideal for both casual listening and professional monitoring.
