Be sure to study "Community/Hearing Loss Forum" and visit the DIY pages.
If there is Costco in your country it should be your first stop. There is only a small
number of manufactures but many many brands to confuse the prospect.
I have on order from Costco Rexton bicore custom ITE aids. Hearing aid hardware/ software priority is for speech recognition with programs to turn on and off features. I do not know how mine will sound on a music program. The audiologist is very important for analysis and HA setup.
