Been thru the hearing aid dance .
The key is what is lost. For most folks its 1000cps to 1500cps and that is what most amplifiers do.
For across the board hearing loss , the simpler TV $29.00 units do better at broad spectrum amplification.
Cosco has only a max 17% markup ( unlike the "specialist " with a 1000% markup) and a 90 day return , full money back policy.
Its individual, but for me $29 is more understandable than the Swiss $2400 units
