New design which features a new integrated wax trap and new silicon material, giving better retention in the ear and making them more comfortable to wear. These attach to the end of Phonak micro tubes and should be used to replace discoloured or damaged domes, usually every six to 10 weeks depending on use and maintenance. Always make sure that a new dome is pushed firmly onto the tubing over all the ridges before inserting into the ear. These domes are supplied as Phonak ‘like for like’ replacements. Please refer all questions as to suitability to your hearing aid audiologist or email us.
