- 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.
