ANC stands for Active Noise Cancelling which is a technology present in some headphones and earbuds that dampens disturbing ambient noise . This noise blocker is produced by capturing the surrounding sound through the built-in microphones in the headphones or earbuds . The sound then gets analyzed and twisted so that the person wearing the audio devise hears less ambient noise . This prevents the need to turn up the volume to compensate for background noise which is better for your hearing .

ENC stands for Environmental Noise Cancelling which is a different technology found in some headphones and earbuds that come with a microphone function . Background noise is suppressed by recording the sounds in the environment and then process them to create a opposite cancelling sound which will neutralize the noise . This way the speaker ’ s voice will be heard clearly over the background noise .

As the technology evolved throughout the years , Bluetooth improved . Each version improved the data transfer speed , connection range , stability , security , and energy efficacy . We are currently on 5.3 . Below are the five main versions of Bluetooth :

We could say that Bluetooth 5.0 has laid the basis for the new family of versions of this protocol . The last major update revolutionized Bluetooth 4 , doubling the speed of file transfer and quadrupling the range , which is the distance over which data can be transferred between them . Since then , the rest of the versions have simply been refining small things .
