I have mild hearing loss, and have had Oticon OPN1 haring aides for over 3 years now. They cost over $6,000. but have been worth it to me as they support Bluetooth connection to iPhone for calls and for listening to audible books from Audible.com. I also have Oticon TV adaptor which feed digital TV sound to hearing aids controlled separately from TV speakers so both my wife and I can adjust sound. I love the TV sound as it is crystal clear including when people speak fast etc. It will be time for hearing aides soon, and my Audiologist is now recommending Phonak which apparently has been improving aides to better dieal with sounds in a crowd such as a dinner table. I would like to get rechargable batteries if they work well. I'd be interested in comments about both Phonak and Oticon.
