1, the noise reduction effect is different: comfortable noise reduction mainly makes people feel more comfortable and relaxed by reducing the stimulation of external noise to people's ears, and adopts the method of weakening external noise, such as adding noise reverse interference to headphones or speakers, so as to achieve the noise reduction effect. Deep noise reduction, through more detailed treatment of external noise, can directly eliminate some specific frequency noise, so as to achieve a deeper noise reduction effect.

2. Different use scenarios: Comfortable noise reduction is suitable for some low-noise environments, such as offices and libraries, and its main purpose is to reduce the interference of environmental noise on people and improve the efficiency of people's work and study. Deep noise reduction is mainly used in some noisy environments, such as airports and construction sites, which can effectively reduce the damage caused by noise and protect people's hearing health.
