If you do not know what size of tube you need:
have a look near the tip of your old tubes – there should be a number usually Red on the left and Blue on the right.
OR
alternately email us (info@hearingaidparts.co.uk) having taken the measurement from the top of your ear (where spectacles would sit) straight down to the centre of the ear canal entrance in mm – please see picture below.

Replace your thin tubes at least ONCE A YEAR for optimal performance
