Thanks for your advice.
I guess the ability to see how the aids are set up now and experiment (after saving the original profile as you recommended) will really help me get the best out of them. it was the thread here that made me consider the Soft Noise Reduction setting:
Specifically, the posting by “Mick” from Colorado in Nov 2023.
I have also been searching the web and found nothing that really explains thoroughly what the various settings are for and how to optimise performance during BT streaming. Its perhaps not surprising that many audiologists struggle too, given the rapid development in HA technology and the range of devices on the market.
Thanks again for your help
