How it works

1. First try to insert the largest ear tip with filter into the ear.

2. If the ear tip feels uncomfortable or is difficult to insert, place the filter into a smaller size ear tip.

3. If the ear tip feels to loose or you have the feeling the ear tip can fall out of your ear to easy, place the filter into a bigger size ear tip too see if you achieve a proper seal. 

4. We also recommend watching our instruction video.

5. In the case your preferred language is not in the packaged manual you can also download our Crescendo manual in 24 languages.
