I think I will be purchasing SE535 special editions (my se530's were stolen a few months ago) and getting custom moulds. (in melbourne, australia)
I have had custom moulds twice before and have not achieved satisfactory isolation. Using them, they isolate momentarily and then come loose.
What are the factors involved in getting perfect custom moulds? Is it the quality and knowledge of the audiologist? (recommendations for Melbourne, Australia would be appreciated) Is it the factory producing the silicone inserts? Is it just the shape of my ears and my head? Are my expectations too high?
Do you have any tips on getting the best custom moulds?
