This electric noise-cancelling earplug can not only instantly reduce noise to protect the users ears, but also allow the wearer to retain normal hearing for daily conversations. The earplugs are equipped with a small microphone that can change the working state of the earplugs by detecting the intensity of external sound waves. When the intensity of external sound waves exceeds a set value, the earplugs will switch to "noise reduction" mode to prevent sound from entering; once the sound intensity decreases, the earplugs will automatically cancel the noise reduction task and return the wearers hearing to normal. At the same time, it also has the function of a hearing aid, which can increase the sound by 15 decibels after simple adjustments. These earplugs are ideal for long-term wear, not only in noisy places but also for everyday use.
