I've always been a fan of my trusty David Clarks. Comfortable and quiet enough that I've never thought of buying a ANR set. Plus, guys I flew with at the Regionals were always replacing the batteries in the ANR's; too much hassle. Now at work I wear Telex or Plantronics. I have one of each. I'm not sure if they make any GA headsets; however, I have used my Telex with earplugs in a Bonanza and it worked just fine.
DC's have great customer service also. If you run em over just send the parts to them and they'll send you a new pair.
Overall, I've always viewed David Clarks as a status symbol for pilots. There's something sublimely cool about DC's. Not overstated or too technical but just good comfortable and sturdy.
