I managed to destroy my Peltor 500 headset yesterday.
I was all set to buy these: 3M Pro-Protect
However, I thought I'd check to see what else is available, and saw MidwayUSA is offering the Walker's XCEL 500BT for $60 (black & green only, other colors are $120): XCEL 500BT
I ordered a set, and if they work for me, I'll get some gel earseals. If they aren't as good as the 3M/Peltor stuff I've had, I'll use them as loaners.
I thought others might want to know about the sale.
