The recently released Bose SoundControl are $900 for a pair.
Audicus sells their low end device at $1000 for a pair.
Costco sells a device that are about $1200 for a pair.
MDHearingAid is probably the cheapest ($400 for a pair!) but they're not programmable and so of limited utility for serious hearing loss.
You will find budget models from the major hearing aid vendors for around $1200 up for a pair.
I was disappointed when they basically doubled the price of their newest device after adding a second mic, which provides a forward focus. I know their cost didn’t increase more than $50. But, they still sell the Air model.
The company was founded to provide a quality aid at a reasonable price and hasn’t been convinced to sell out to the cartel yet.
I’m really hoping Apple will do something in this market.
