Very useful

Works perfect for listening to music and quiet when not, adjusting the hearing knob is perfect when having a conversation without taken the muffler off.

Worth the money

Damn my ears are bad. Can hear better with them on. Very tough. No dust protection over charging port. Doesn't seem to care. Worth the money for sure.
