What is QuietSmart™ 3.5 tech?
EarFun QuietSmart™ 3.5 tech is an AI Scene-Aware Adaptive ANC algorithm, delivers total immersion without
compromising audio fidelity. Powered by a multi-microphone array and real-time AI soundscape analysis, it
dynamically adapts to your environment, fit, and wind conditions. QuietSmart™ 3.5 generates precision
anti-noise waves to instantly neutralize background distractions—from deep engine hums to ambient
chatter—while preserving the full warmth and detail of your music.

Advanced Adaptive ANC Technology for Superior Comfort and Performance
Our latest Adaptive Active Noise Cancellation (ANC) technology is engineered to enhance user comfort by
significantly reducing the reliance on achieving a tight seal with the ear canal. This innovation
eliminates the need for users to exert pressure or twist earbuds into position, thus avoiding potential
discomfort. Users often face challenges in selecting appropriately sized ear tips or maintaining
consistent insertion methods. Moreover, the fit can vary with different activities such as running,
walking, or head movements. Adaptive ANC technology dynamically adjusts its performance in real time,
continuously modulating based on earbud fit and external noise intrusion. This ensures a uniform ANC
experience across various environments and activities.
