I am finding this site rather uselful...

I currently wear a pair of BOSE Quiet Comfort II headphones, up to 12 hrs/day, nearly every single day. I am starting to experience some discomfort, if I listen to music through them for more than 1-2 hours at a time and would prefer to have the music on for a lot longer. I need to ask the good doctor a few questions, but it looks like I'll be buying one of the mini amps. Thanks man.
