Disappointed in the quality.  I have worn dual-comm Peltors before, and while I didn't expect the same quality in a lower-end model, I did expect more than this.  I felt as though I might break it trying to put in the batteries.  It wasn't as comfortable as other earmuff earpro I have worn.  And  the sound quality coming through the speakers was not high enough for me to be confident that the pair I had was working properly, although it did effectively cut out when firing a 12-gauge (hence 2 stars).  Returned.
