Insert the Earphones

Roll the Foam Eartips into the smallest diameter possible and insert them well into the ear.

NOTE: Since the Foam Eartips are 12mm long, the correct insertion depth into the ear canal is obtained when the rear edge of the Foam Eartip is 2-3mm inside the entrance of the ear canal.

Hold the Eartip in the ear canal until the foam expands to fill the canal.

NOTE: Once the Eartips are in place, it will be difficult for the patient to hear instructions from the test technician.
