You can watch the video here: Instructional Video – Inserting Earplugs. If, after watching the video and following the enclosed instructions, you still can't get the earplugs to fit properly, you can book a check-up appointment at a location, date and time that suits you best.

The Audinc Pure Tones earplugs are equipped with linear attenuating filters that reduce sound evenly. This preserves sound quality without distortion, so you can enjoy clear sound even in noisy environments. Whether it's music or other sound-intensive situations, these earplugs protect your hearing effectively while retaining the natural tone. There are two filter options: the flat filter for balanced sound across all frequencies, and the tube filter for extra attenuation of high tones. Both filters protect against harmful sound, but the difference lies in the way the sound is experienced.

That depends on the type of earplugs you choose. You'll find the prices listed with the various earplugs in our range.

The Click filter is an optional upgrade for the Audinc Pure Tones earplugs. This filter lets you adjust the attenuation at the push of a button. It gives you the flexibility to tailor your protection to different sound conditions. When you need more sound reduction (at a loud festival, for example), you can easily switch the filter to a stronger setting for optimal protection.

Flat filter (Pure Tones): This filter provides consistent attenuation across all frequencies (high, mid and low), so you retain the sound in a natural way. It delivers a balanced sound reproduction without distortion, ideal for people who want to experience clear, unaltered sound. Non-linear filter (Custom Music): This filter attenuates the high tones more, resulting in a somewhat duller sound. It's ideal for situations where you need extra protection for the high frequencies. Both filters offer the same protection against harmful sound, but the difference lies in the way the sound is experienced: The flat filter delivers a clear, natural tone. The non-linear filter makes the sound less sharp by attenuating the higher frequencies. This option is often a bit more affordable.
