- Airy C-bridge: The flexible connector is now 25% softer and made of skin-friendly liquid silicone, improving long-term comfort.
- Reduced Footprint: Each earbud is lighter at 5.1g (down from 5.6g). The “Comfort Bean” that sits behind the ear is 11% smaller, and the charging case is 17% narrower and 14% lighter.
- Interchangeability: Like the original, there are no designated left or right buds; the system auto-detects which ear they are on
- Dual-Diaphragm “Turbo” Driver: A new 10.8mm driver setup reportedly doubles the bass output and volume compared to the first generation.
- Adaptive Listening: Features an NPU-driven Adaptive Volume and Adaptive Voice Enhancement that automatically adjusts audio levels based on surrounding noise (e.g., traffic or office chatter).
- Advanced Call Clarity: Uses a 3-mic system (some sources mention 6 total mics) with a bone conduction sensor and AI algorithms to isolate your voice from wind and background noise.
- L2HC & Spatial Audio: Supports high-resolution L2HC audio encoding and spatial audio with reduced head-tracking latency.
- Expanded Gestures: In addition to tapping, the C-bridge now supports swipe gestures for volume adjustment.
- Head Motion Control: Users can answer calls by nodding or reject them by shaking their head, a feature inherited from high-end FreeBuds models.
- Weather Resistance: Improved durability with an IP57 rating for the earbuds (dust and immersion resistant) and IP54 for the case.
