**Revamped Battery System | Stable 40H Total Playtime & Optimized Fast Charging** The redesigned power-management chip cuts idle power loss. It maintains steady 8-hr single-ear runtime under mixed music-call use, delivering up to 40H total playback with LED-display case for over 500 songs. The enhanced fast-charge circuit ensures consistent 90-min playback from a 15-min charge even after repeated deep discharges, eliminating sudden power drop-offs of older earbuds. **Redesigned U-Shaped Semi-In-Ear Fit | All-Day Comfort & Anti-Slip Performance** Re-engineered U-shape based on mass ear-shape data. At only 3.9 g per earbud, the optimized 65:35 weight distribution prevents slipping during movement.

The upgraded modified TPU material reduces stuffiness by 50% with better breathability, solving long-wear ear soreness common in early-generation semi-in-ear earbuds. **Upgraded Dual-Core Bluetooth 5.3 | 0.05 s Low Latency & Strong Anti-Interference** The dual-core transmission chip enables 1-s auto-reconnection. It achieves 20% lower power consumption, 30% more stable signal and 25% better anti-interference vs last-gen models. It reduces stutter and audio-video desync in crowded signal-rich environments for smooth gaming & movie experience. **Overhauled Hi-Fi Acoustics | 13.2 mm Driver with Tuned Cavity Structure** Revised acoustic cavity & titanium-plated diaphragm damping. The reinforced 13.2 mm driver delivers deeper bass with less mid-high-volume distortion, plus clean non-harsh treble.

The re-tuned EQ enhances transient response to restore rich audio details for multiple music genres. **Full-Stack Optimized Touch Control | IPX7 Water-Resistance & Improved Charging Case** The updated touch algorithm adds anti-mis-touch filtering logic, boosting touch accuracy by 18.5 % to avoid lag & unresponsive taps. IPX7 sweat-proof earbuds (case excluded) with reinforced sealing. The ergonomic compact case speeds up Type-C charging; dual LED indicators show real-time battery status.
