Silicone headphones (earbuds / ear-buds) for koss plug

Step 5 Remove cured silicone tubes and trim

After the caulk cures, remove it from the ink tubes. Twisting the ink tube within the silicone tube seemed to help detach it from the silicone.

Find the ideal diameter of the silicone tube that fits your ear. Start from the narrow end of the silicone tube and trim bits off until you have  snug fit. Then cut the other side of the tube to leave a section a bit longer than the Koss plug. Leave a long enough tube to prevent it from lodging in your ear if it detaches from the base speaker.

Repeat this process for your other ear. Taper the ear-end of each tube to make it easier to insert.

Enjoy your new earplugs, see you on the road!
