When do I have to replace the foam tips?
It depends on how they are used, the hygiene and earwax secretion of each user. Generally, we recommend you to replace them with new foam tips after about 2 months. Failing to carry out such a careful measure, there is a risk that the earwax will obstruct the small inner tube preventing the right sound amplification and weakening the earebuds-enabled amplification. Moreover, after some time, the “memory foam” characteristic begins to abate, following the reduced flexibility of the rubber tips, which thus become less comfortable.
