What is EarFun's
EarFun’s QuietSmart™ Digital Tech is an upgraded Hybrid Active Noise Cancellation [ANC] System to maximize noise-canceling performance and the best audio experience with a noise reduction depth of up to 40dB, features two microphones (Feedforward-Mic & Feedback-Mic) on each earbud,captures ambient noise and in-ear noise, passes the data of both sides to the internal Noise-Canceling System that nullifies it with equal anti-noise before it reaches your ears.
The Feedforward mic [FF Mic] detects ambient noise and passes through it to the internal ANC system to produce an opposite signal to cancel out the ambient noise.
The Feedback mic [FB Mic] is set inside of the earbud to detect the in-ear sound and unwanted noise. This helps the ANC system to produce corrections in the signal to eliminate the in-ear noise with a broader range of sound frequencies.
Customized Anti-wind Noise Algorithm
Upgraded QuietSmart 2.0 adds a customized Anti-wind Noise Algorithm*: Wind noise is one of the most annoying effects of using wireless ANC earbuds outdoors. EarFun's engineer has developed a new anti-wind noise algorithm and improved Feedforward & Voice Pick-up Microphone position design to anti-wind noise. When the Anti-wind noise algorithm actives automatically, the Feedforward mic reduces its sensitivity, thus suppresses wind noise from being heard. In this way, the Anti-wind Noise Algorithm in the QuietSmart suite provides a better immersed noise-cancelling audio experience even with outdoor activities.
QuietSmart™ ANC Algorithm
Combining with EarFun's QuietSmart™ ANC algorithm, it senses and adjusts to music and noise signals, as well as acoustic characteristics between the driver unit and ears, at over 400 times per second. The QuietSmart™ tech also will fill in the missing sound frequencies which cause by the ANC process. It will tune music to the shape of your ear for truly immersive sound and consistent ANC listening experience.

Enjoy Travelling with QuietSmart™ ANC
Whether you want to spend the trip listening to your favourite music or simply blocking out the noise around you so you can enjoy travelling without noise interruption, wireless headphones with QuietSmart™ hybrid ANC can help you with it. Further, while picking the best gadget for flying, it should be wireless headphones with QuietSmart™ hybrid ANC. As they'll deal with both low-frequency noises - like the deep rumble of an aircraft - and on higher frequencies like announcement voices, helping you tune out of a noisy airplane and into your soundscape.
