Interestingly, I have yet to find I have the horrible feedback problem people are talking about in this thread with my APP3, but I do in my Honeywell syncs, about 1 day in 3. And as I wear glasses all hearing protection in the earmuff style block less noise than the APP3 - though I normally wear both.
