How to measure wire length for Oticon receiver?

There are a couple of threads but none of them provide a ruler or a type measurement to determine length

IIRC, the thread was a Phonak RIC thread and there is a photo of a ruler that is fit on the ear. The distance is given in terms of inches from a point.

Here you are.

There is a difference in length between manufacturers as stated in this thread

Oticon vs Phonak receiver lengths

I’m pretty sure Neville has the right diagnosis. And the fact that I’ve done very well in the past with my hearing loss and domes I’ll wait for that option to materialize.
