We want you to return to the sound of enjoying everyday life. Your satisfaction is our biggest asset.
Make a micro screwdriver available: the volume increases clockwise and counterclockwise decreases.
There are three different sizes of earplugs in the box, please choose the right one.
If there is any noise, please turn up the volume to make sure that the earplugs are in close contact with the ear canal so that the sound does not leak.
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.
