I have pretty crappy hearing after 34 years in the fire department. So I bought a pair on the recommendation of a friend. He loves his, and uses the Bluetooth feature as well.
I really like mine, but as noted from others you have to experiment to get the correct foam tips.
For myself, I use the extreme noise reduction tips, but apparently my ear drums are different sizes. So I use different size tips. When I finally figured it out, I now have hearing enhancement, loud noise (gun shot) hearing protection, along with a comfortable fit.
I don't see myself ever using the Bluetooth feature, but I am very satisfied with the hearing enhancement.
