Here are some additional tips you can try to make the earplugs more comfortable to use while sleeping.
Fellow these steps
- Heat as instructed and let cool for 30 seconds.
- After placing in your ear, apply pressure to simulate sleep, or lay down on your side as you would while sleeping.
- Allow the mold to completely cool.
- After the mold is cool, check for any sharp edges or ridges.
- If there are ridges, heat (in hot water) for one minute.
- Use your finger to smooth/round the edges.
