I work in a BUSY restaurant and at the end of the night my ears ring when I get to laying down for bed. I bought these to protect my hearing from the damaging noise of music, stacking plates/ glasswear, and overall crowd noise. I love them! They feel like they block the bad vibrations out, while still allowing me to hear my tables orders. I won’t hear my name being called across the restaurant, but I’m not bothered by that. When I wear them, I have no ringing at the end of the night :) I love that they come in a case that is an attachment to your keys. Easy storage, and you won’t lose them!
