Just spoke to him as I wrote reply to RFGuy. The hearing aides are comfortable, however the receiving radio words are somewhat garbled and he at times cannot understand them. He is a very experienced GA and now RAA pilot and this has only been an issue in past 18 months, and he's up to date with hearing aide checks.
Tv reception via the above device is great and would be good if he can connect similar in the Vixxen.
