Clean a Gear S3’s speaker and microphone openings by wiping around them—not by pushing a tool into them. Remove the watch from your wrist and charger, then gently wipe its exterior with a clean, dry, soft lint-free cloth. Samsung advises against compressed air, abrasive materials, soap, and cleaning agents; if the openings are wet, dry the watch thoroughly before testing sound again.
Clean around the openings, not inside them
- Remove the watch from your wrist and disconnect it from the charger. Use a clean, dry, soft lint-free cloth.
- Wipe the exterior gently. Work around the speaker and microphone openings with light pressure. Do not poke, scrape, or push cloth fibers or liquid into either opening. Samsung identifies a built-in speaker and a microphone on the mainboard, but does not provide instructions for inserting a cleaning implement into either acoustic opening. Samsung’s Gear S3 parts overview identifies those components.
- Stop at the exterior. Samsung’s general smartwatch cleaning guidance says not to use soap, cleaning agents, abrasive materials, or compressed air. It mentions a soft-bristle toothbrush for stains or foreign material generally, but does not direct users to brush inside the speaker or microphone openings. Do not treat that general suggestion as permission to brush into them. Samsung’s smartwatch cleaning guidance lists the methods and materials to avoid.
If the Gear S3 got wet
Dry the watch thoroughly with a clean, soft cloth before retesting audio. Samsung says sound may not be heard clearly during a call if the device has been immersed in water or its microphone or speaker is wet. The Gear S3’s IP68 rating is conditional: Samsung Singapore’s support page, last updated October 8, 2020, says not to immerse the watch deeper than 1.5 m or longer than 30 minutes, and warns that water or dust can still enter and damage it. That rating is not a reason to rinse the watch as a cleaning method. Samsung Singapore’s Gear S3 water-resistance guidance gives these limits.

When cleaning does not fix the sound
Once the watch is dry and the exterior is clean, test the speaker and microphone again. If sound remains unclear, do not escalate to pins, swabs, brushing inside the openings, or air; Samsung’s troubleshooting guidance says service is required when speaker or sound problems continue after cleaning. The cited Samsung guidance does not document a method for clearing stubborn debris lodged inside an opening. Samsung’s smartwatch sound troubleshooting guidance describes when to seek service.
