5.2 Inserting the Ear Plugs
- Gently pull your earlobe downwards to straighten the ear canal.
- Insert the earplug into your ear canal until it feels snug. Approximately 80% depth is recommended for most users.
- Release your earlobe and allow the earplug to settle.
- Check for a secure fit. If you experience noise leakage or the earplug feels loose, try a larger tip size.
6. Operating Instructions
6.1 Adjusting Noise Control Modes
The IDE11 M3 earplugs feature a twistable dial to switch between three distinct noise reduction modes:
- 17dB Mode (Leisure Noise Reduction): Suitable for office conversations, keyboard clicks, and general casual environments.
- 21dB Mode (Concerts and Parties Noise Reduction): Ideal for moderate noise environments such as concerts, parties, and gatherings.
- 35dB Mode (Focused Work Noise Reduction): Provides maximum noise reduction for sleeping, snoring, subway travel, or tasks requiring high concentration.
To change the mode, gently twist the outer dial on each earplug until you feel it click into the desired setting.

When not in use, always store your earplugs in the provided magnetic carry case. This protects them from dust, dirt, and physical damage, ensuring their longevity and hygiene.
8. Troubleshooting
- Insufficient Noise Reduction: Ensure the earplugs are inserted correctly and snugly. Try a different size or type of silicone tip to achieve a better seal. Verify the adjustable dial is set to the desired noise reduction level.
- Discomfort or Pain: If you experience discomfort, try a smaller tip size. If pain persists, discontinue use and consult a medical professional.
- Earplugs Falling Out: This indicates an improper fit. Try a larger tip size or ensure the earplug is inserted deeply enough to create a secure seal.
