This is a FULL SHELL MOULD with a reduced helix ( note the shortening of the bit at the top). This modification helps the user insert the ear mould better. The ear mould is finished very well and it has a matte type finish, not as ‘rough’ as a silicone mould, but not as ‘slidey’ as a typical hard acrylic mould. In this case the mould had a longer than normal ear canal extension, reaching down to the second bend. The Phonak Bolero’s feedback controller is superb, so the end result is excellent for this patient with very severe hearing loss….
