I am currently trialling some Wides Dream 440 Fusion RIC aids. The audi first tried tulip domes, but they were too open.
We then went to small double domes, but they felt too large. The extra small double domes are too small.
Since I had some Starkey occluded domes. I am trying them. They appear to fit the receivers OK.
Has anybody else had experiences mixing brands on domes & aids? If this does not work, my only alternative for these aids would be using custom ear tips.
