Here are some tips for getting a good fit:
- Have someone help you mold them.
- Use a mirror so you can see where you are moving the material.
- Start with a silicone tip that is a size smaller than you need. This makes it easier to get into your ear and start molding. After the mold is cooled, swap out the tips for the size you want.
- Try not to “over mold”; that is, try not to swipe/spread the material too much. Typically, gently pushing inward and upward works well.
- Use the folds or ridges of your ear to help lock the mold in place.
- Have your music playing while you mold. This helps ensure everything is lined up right. For most people, the ear canal goes forward (toward the eyes), so angling the earbud forward will help improve fit and sound.
- If you have small ears, you can trim the mold down a little with scissors after it is heated. Just snip a little off the top.
- If you have large ears, try to create more of a shell than a plug—this helps cover the concha (bowl) of the ear.
For the better noise isolation:
- Use a bite block while molding—this opens the ear canals and allows the material to get a little deeper.
- Mold as instructed and let cool for one minute; then gently press into the ear again and let cool for the full five minutes.
