My year old peltor sporttac ear muffs were great up until a month ago. Now they've started hissing and crackling in my right ear. It's not a constant thing but comes and goes. It's exceptionally irritating so I've stopped wearing them, right pain for something so pricey.
Has anyone had a similar issue? If so, what was the cure? It's got a brand new pair of Duracell batteries in. Seems odd!
