Descriptions:

> Comprehensive Upgrade
> Refined Housing For Enhanced Comfort
> Precision-machined Aluminum Shell Material, Maximizing Bone Conduction Performance
> Utilizing PZT piezoelectric technology, the bone conduction system operates by driving the housing through a vibration unit, effectively transmitting mechanical energy.
> The high-rigidity aluminum alloy shell exhibits a hgiher natural resonance frequency and lower amplitude, reducing unwanted vibrations and secondary resonances - delivering purer sound with a quieter background.

> 11.6mm Mid And Treble Frequency Bone Conduction Driver
> Japanese Silver-Palladium Alloy For Authenic Sonic Reproduction
> We incorporate Japanese-imported silver-palladium paste with an increased palladium ratio from 2% to 5% enhancing conductivity in the piezoelectric ceramic speaker. This boosts clarity, brilliance, and sensitivity. The piezoelectric bone conduction unit has a more powerful transmission effect and is easier to driver.

> 12mm Custom Dual-Cavity Dynamic Driver
> Deeper Bass With Reduced Nonlinear Distortion
> The dual cavity dynamic driver is engineered to provide optimized airflow paths during diaphragm movement. Independent cavities allow smoother, unobstructed airflow, significantly minimizing turbulence and phase inconsistencies.
> This dramatically reduces nonlinear distortion, particularly under dynamic pressure and in low-to-mid frequency ranges - ensuring greater tonal accuracy and purity.

> High-Power DAIKOKU Coil Optimized Magnetic Circuit Design
> Wider Dynamic Range And More Impactful Listening Experience
> Neodymium magnet motors with higher magnetic flux density improve transduction efficiency and linearity. Combined with a high-power DCCA (DAIKOKU copper-clad alumium) voice coil, the system responds more accurately to current variations within a strong magnetic field. This enhances separation and resolution in mid-to-high frequencies.
> Extensive refinement of the magnetic circuit has been performed to achieve deeper low-frequency extension without compromising stuctural compactness. The result is increased conversion efficiency, quicker transient response, tighter control, and an overall more energetic sound presentation.

> Smooth, Balanced Tuning Across All Frequencies Immersive And Detailed Sound Signature
> Glossy Highs And Ultra-smooth Response For An Enveloping Musical Experience
> Winter II is acoustically tuned for enhanced instrumental ambiance and textural realism. With upgraded dynamic and bone conduction drivers supported by higher magnetic flux and advanced piezoelectric ceramic performance, the sound is ethereal yet defined. Trebles are naturally luminous. The soundstage is open and organic, with precise imaging and spatial layering. Vocals are clear and emotional; high frequencies are airy with extended range and space. Tonal transitions from bass to treble are seamless - effortless control across the frequency spectrum.

> 22% Size Reduction Compared To Previous Generation
> Slimmer Profile, Uncompromised Performance.
> The redesigned housing conforms more ergonomically to the ear canal, allowing more efficient bone conduction transmission and improved wearing comfort.
> The redesigned dual-cavity dynamic driver structure is reduced, and the double optimization of the bone conduction bracket makes the earphone stress-free to wear for a long time.

> 5-Axis CNC Aluminum Shell
> Flawless Chamfering And Seamless Integration - Crafted With Precision
> Anodized High-Gloss Finish
> The aluminum shell undergoes anodic oxidation, forming a robust surface oxide layer that enhances corrosion and wear resistance.
> Metaliic Acoustic Properties
> Aluminum alloy housing offers structural rigidity and mechanical stability. It is durable while also helping to reduce unnecessary resonances.
 
> Industrial Design
> Redefined Curvature, Inspired By Elegance And Motion
> Smooth And Sleek - Just Like The Sound It Produces
> Winter II draws inspiration from the "Year of the Snake", integrating serpentine contours into the iconic skiing lines of the original Winter.

> Single Crystal Copper Hand-woven Upgraded Cable Supple, High-Purity Transmission Line
> High-purity Copper In Litz T2 Architecture
> The cable adopts a Litz T2 construction, in which high-purity copper is divided into multiple independently insulated strands - effectively eliminating high-frequency skin effect. Each wire conducts audio signals with maximum efficiency. The combination of ultra-pure copper and precise Litz winding ensures greater conductor cross-sectional area, significantly reducing AC resistance, minimizing heat generation, and improving signal integrity. The result is a cleaner, more transparent sound.

> Outer Diameter (Single Strand): 1.55mm
> Core Structure: 0.06mm x 7 x 7 OOC Copper
> 4-Core Single-Crystal Copper Cable, 196 Total Strands
