The Ohropax Silicon Aqua earplugs are designed for repeated use, but their lifespan depends on various factors.

- Care and cleaning: Regular cleaning after each use can significantly extend the service life. Sweat and earwax should be removed quickly to avoid any negative impact on the material.
- Conditions of use: The service life varies depending on the frequency and duration of use. With regular use, you can expect them to last for about one to one and a half years, but they can last longer under optimal conditions.
- Personal factors: The user's sweat and earwax composition can affect durability. Some users may be able to use the earplugs for longer without compromising the protective effect.

Overall, the Ohropax Silicon Aqua earplugs can be reused several times, but it is advisable to have them checked by a professional every six months and to clean them regularly to maximise their lifespan.
