The earplugs consist of two parts: the coloured, round filter and the transparent earplug. The filter already comes delivered inside the larger earplugs (M: ø 7 – 12 mm).

First, insert these earplugs into your ear canal in accordance with the instructions. If this is difficult or feels uncomfortable, try again with the slightly smaller earplugs (S: ø 6 - 11 mm).

Use one hand to pull the outer ear slightly outwards and upwards, and with the help of the tongue, carefully insert the earplug into the ear canal until it is in a secure and comfortable position.

Changing the filter: To remove the filter, press the earplug just under the filter until it ‘pops’ out of the earplug.

To insert the filter, ease it into the larger opening of the earplug with the ear symbol facing outwards. The filter should be inserted at a slight angle and upside down. Then, push the ear symbol downwards a little to ensure the filter is correctly positioned inside the hollow area. The filter can only provide the certified noise-reducing effect if it is inserted correctly!
