Not very good at sound reduction and the sound part has a small echo. Not worth $30

This is the first pair of Electronic ear muffs I have ever used, and I did get them on sale for $20. That said I am very happy with their performance, they do what they say they will. They cut out for a .22 shot, or even the sound of a tailgate being closed. I will buy a pair for everyone in the family (4 more pairs), it sure saves the yelling/removing standard muffs to talk. Higher priced models may be higher quality, but these are a practical option that beats any traditional ear protection.
