Go ANR now. It's an investment for the long term. The new DC One X seems to be very good. Bose A20 or QC15/25+uFlyMike do work and Lightspeed products are also popular. Try them out if you can.
I wish I bought ANR from the beginning. I am using DC 10-13.4. Good headset, but after a 3-hour flight my head is toasted.
