Why people use it

Evidence at a glance
They can reduce noise, but benefit for sleep depends on the environment and fit. Persistent ear pain or discharge needs assessment rather than continued insertion.
Confidence: moderate
Device safety
Placement, electrical-device and medical precautions from the manual and reviewed sources.
Earplugs can irritate the ear canal and contribute to outer-ear infection. Keep them clean, follow fit instructions and account for reduced awareness of alarms or other important sounds.
