▲We want you to return to the sound of enjoying everyday life. Your satisfaction is our biggest asset. ▲This personal device features a low profile that is more comfortable to wear in you and barely visible. ▲Provide a micro-screwdriver - the volume clockwise increases and the volume counter-clockwise decreases.There are three different ear sizes in the package, please choose the right one. ▲If there is noise, lower the volume to make sure the ear plugs are in close contact with the ear canal to make sure the sound is not leaked. ▲The left ear is blue and the right ear is red. When wearing there is no difference. We recommend that you try the 45-day device because it takes 2-6 weeks to adjust the sounds that have not been heard for many years.
