Loop is a Belgian company that makes reusable earplugs for events, focus, travel and sleep. Its product range uses different designs for varying noise reduction. Models may preserve clarity, maximise muffling or offer adjustable modes.

How it works
Soft ear tips create a seal in the ear. In Experience and Engage models, an acoustic channel and filter reduce sound energy across frequencies while keeping sound natural. Quiet models use solid silicone for broader blocking. Switch models include a manual dial that changes the acoustic path and offers three reduction settings.

Key considerations
Protection depends on choosing the correct tip size and achieving a secure fit in each ear. Reduction ratings vary by model, and no earplug removes all sound. Users still need certified protection for hazardous workplaces or extreme noise. Earplugs should be cleaned and used without preventing awareness of important alarms.
