The IDUN Guardian and especially the Eartips should be cleaned after every use.


It is recommended to clean the Eartips and Wings after every use with isopropyl alcohol wipes to remove any debris and disinfect the sensors in case the device is used by multiple users. Removing built-up earwax or sebum will have a positive effect on signal quality.

All other components, can be wiped with isopropyl alcohol wipes or a soft cloth.


Once all components have been cleaned and disinfected, they should be visually inspected for any signs of remaining dirt. If the components appear dirty, repeat cleaning as described above until clean.

Ensure all components are completely dry before repackaging.

Visually inspect for signs of damage, for example, cracks or loose connectors in the plastic enclosures. Do not re-package or re-use components that are showing signs of damage.

In case of damage

If components do show signs of damage, please reach out to IDUN Technologies to discuss best practices in recycling or returning the materials.

Caution! The device is not washing machine, dishwasher or tumble dryer proof. Please do not put any of the IDUN Guardian components into either of these appliances.

Caution! Do not apply liquids to the device or submerge the device in water or other liquids. The device is not rated for submersion in liquids and may lead to fluid ingress, equipment damage or electric shock.

Caution! Do not splash water on the IDUN Guardian Earbuds as this may impede the functionality of the device.

Important! Cleaning protects the device from a build-up of potentially harmful bacteria and protects the device material.
