Inspect the eartips before every use for degradation or deformation.  The integrity of the eartips is vital for proper hearing protection. It is suggested that the eartips be replaced approximately every 3 months depending on extent of use.

Additionally, the wearer should ensure that:

  1. The eartips are fitted, adjusted, and maintained in accordance with the manufacturer's instructions as stated in the manual included with the product.
  2. The eartips are securely attached to the ISOtunes product and worn properly in noisy environments.
