iFLYTEK AiNote Air 2 Electromagnetic Pen Refill Set

The IFLYTEK AINOTE Air 2 Electromagnetic Pen Refill Set (XF-DX-W3TI) contains precision replacement tips engineered specifically for the AINOTE Air 2 active stylus. Each refill uses durable, low-friction materials and a geometry tuned to reproduce the tactile, paper-like resistance of the original nib — preserving line fidelity, stroke micro-variations and tilt/pressure nuance required for accurate handwriting-to-text conversion and shape recognition. The refills are manufactured to maintain the stylus’ full feature set including high-resolution pressure sensitivity (4096 pressure levels), near-zero latency and robust palm rejection, ensuring predictable digital ink behavior across all writing speeds and angles.

Key Features:

• OEM-grade replacement nibs optimized for the AINOTE Air 2 electromagnetic stylus.

• Preserves device-native 4096 pressure sensitivity and high responsiveness for fine line control.

• Paper-like friction profile: engineered tip material and shape for consistent tactile feedback and minimal glide.

• Full compatibility with AINOTE Air 2 palm-rejection and handwriting recognition systems — no calibration required after replacement.

• Quick, tool-assisted installation and removal using the integrated clip / nib-removal feature; V-slot removal design used in official guidance for safe extraction.
