Signia Thintube 3.0

Signia Thintube 3.0 are supplied as pairs - one left marked in blue and one right marked in red. There are 5 lengths - 0, 1, 2, 3 and 4 in two thickness ranges i.e. 0.9 and 1.4.

The thicker 1.4 Thintubes are required for use with higher power hearing aids as the larger tube helps with sound transmission and reduces the chance of acoustic feedback.

Signia Thintube 3.0 each have a nanocare wax filter which needs to be replaced on a regular basis since a build up of wax will block the sound. They are very easy to change - watch the video on the product.
