Earmuffs - Lot of 10

Race cars are loud.  Spectating at races can border upon deafening.

While watching a 6 hour race at Watkins Glenn this past summer, I sat at the very top of the grandstands at the start/finish line for the final hour of the race.  The sound of the cars was overwhelming.  Maybe it was the wind direction.  Maybe it combined with the resonance of the engines off the banks of aluminum seating.   The experience was nearly intolerable.  Having a good set of earmuffs is going to be key to surviving a 24 hour race.

I figure the earmuffs offer two good options for use.

1. Placed over earbuds so a radio broadcast can be heard, while reducing the continual drone of the race cars
2. Combine with in-ear plugs for added sound reduction - I've read that NASCAR and NHRA folks do this

A bit of research turned up the Howard Leight Thunder T3 as a good option "designed with all-day comfort in mind. Thunder headband earmuffs feature a unique dual headband for better positioning and breathability, and a non-deforming outer headband that minimizes pressure on the head....The Thunder series features patented Air Flow Control™ technology for optimal attenuation across all frequencies and also snap-in ear cushions for easy maintenance."

These cost about $25-30 each.  However, I found a lot of 10 on Ebay for $99.  Anyone interested?  I may just buy them.  Can you guess what you are receiving for Christmas?
