I'm looking for something that can double as hearing protection and a communications headset like the MSA Sordin or the Peltor Comtac. I see them used on eBay for a significant reduction over the MSRP. I've heard the genuine ones out of the box don't interface well with radios like the Baofeng UV-5R and either have to be modified themselves or get some kind of special PTT switch but ultimately that's what I'd like to use with it. Apparently some of the replicas do work out of the box with these radios so I'm tempted to try it despite the obvious downsides of using knockoff equipment. What are your recommendations?
