I just bought a nicely priced set of Peltor A/O Safety ear muffs/hearing protection for $49 at Home Depot that has a built in AM/FM digital tuner and AUX input!! 
  
  I will highly recommend them for working on and fabricating on a car!!  Cuts out 22 db and has great music input.   The AM/FM radio uses batteries..  but the AUX input from your iPod or MP3 doesnt require any batteries.  The radio sucks flat out.. needs a better antenna. 
  
 Combine this headset with your blackberry and pandora radio.. and its perfect.   
  
 
  
  
  With my car on the rotisserie and working 3-4 hours at a time with a air chisel and 4 1/2" angle grinder it makes life a lot more relaxing. 
  
  
** I'm not trying to sell this.. but if anyone is looking for a nice headset with hearing protection, its awesome **
