I lost my hearing at the age of 4/5 years old due to measles and have been wearing NHS hearing aids almost 30 years. My loss is stable and has not changed at all in those 30 years.
At the moment I’m using a 7 year old pair of oticon spirit zest (NHS name) currently waiting for a Costco appointment for hearing check and new hearing aids as my oticon are starting to show wear and tear and have been fixed several times in the last year. I use beltone moulds which I have loved due to the fit but the moulds wear out quickly with tube changes.
Brands od Hearing Aids I’ve had in the include oticon, phonak, Phillips, siemans and a few others I cannot remember the models as the list is long and changed quite often due to software compatability in my school years to fix issues with loop systems, radio aids or phone usage.
