Thanks, I let it sit overnight, and we're back in business!
I saw another thread titled "Perspiration problems" and I think that was my issue. It was working fine yesterday morning, and in the afternoon I went for a 5K run. When I came back, I took a call on my headset, and I was still very sweaty. I think the perspiration messed up the headset. Letting it dry out overnight got it back in working order. I powered it back on this morning and all is well!
