For the cost, these are great little hearing aids, especially since they are rechargeable. Filtering of background noises or loud sounds in large public areas is somewhat difficult/not effective, so cannot be compared to the multi-thousand dollar ones from the specialist hearing places, but for a boost in clearly hearing close proximity conversations, they are great.
Don’t know why people are paying thousands of dollars for Hearing AIDS when there are these options available! My BTE aid has been a godsend with ease of use, no fiddly batteries as the aid is rechargeable, feels secure on ear and almost undetectable with the right hairstyle & definitely does the job. Very worth a try as everything is a personal choice of course👌
