Over time, acoustic tube can be blocked with condensation, dirt, earwax or sweat. We recommend routine cleaning to maintain the performance:
- Remove the acoustic tube from the Eartune Radio.
- Completely submerge the acoustic tube (and its connected clear parts) in warm water for 10-15 minutes. Do not use any soap, detergent, cleaner or chemicals - just water.
- Remove, and pat dry the exterior of the acoustic tube and its parts.
- Then, use compressed air (with straw is the most effective and efficient), to clear of any water / debris out of the acoustic tube.
- Repeat this process a few times until all acoustic tube is cleaned and fully dried.
- Ensure to fully dry acoustic tube and parts, then attach back to Eartune Radio.
