Ordinary earphones physically block external noise. Basically, this type of headset prevents noise by establishing a good seal between our ears and the headset. The soundproof and isolated earplugs fit our ears to eliminate external noise. The earmuff models that always fit the ears have thickened cups designed to block outside noise to the greatest extent. bluetooth noise cancelling headphones use digital signal processing (DSP) technology to actively eliminate sound waves in ambient noise. In short, when you see "noise reduction" or "active noise reduction", it means that the headset has a built-in microphone and audio processor that can "listen" to surrounding sounds and play the opposite sound to eliminate them. This is called destructive interference. Most decent models can handle constant environmental noise (such as conversations, air-conditioning equipment, jet engines, etc.), but it is difficult to adapt to sudden changes such as someone yelling or a sudden change when the door is closed. bluetooth noise cancelling headphones The best option is that you can’t hear or even hear music while sitting in an airplane seat. Even better, bluetooth noise cancelling headphones can bring a peaceful environment even if there is no music playing. Again, these are headphones that you should pay attention to when traveling, because the bluetooth noise cancelling headphones purpose is to eliminate surrounding noise. If you need to hear the surrounding environment to determine safety messages, try not to choose bluetooth noise cancelling headphones.
