Samsung earbuds emit a call sound when not worn

The touch-sensitive sensors on your Samsung earbuds automatically detect when you're wearing the buds. If the earbuds are connected to a compatible device, the earbuds will emit a sound when a call comes in.

To reduce battery consumption, the earbuds will deactivate when you remove them from your ears or if they cannot detect that you're wearing them.

If the touch-sensitive sensors on the earbuds are dirty, have smudges, or come into contact with certain objects, the earbuds may function as if they're inserted in your ears. This will cause the earbuds to emit a sound when a call comes in on the connected device, even when you're not wearing them.

To prevent this from happening, keep the earbuds clean, make sure you are wearing them properly, and keep them in the charging case when you're not using them.
