You can't beat the quality and workmanship of DC's headsets. They are tough and reliable lasting you for years with little or no trouble. I once had a 'lightspeed' when they first came out, lasted about 6 months before the plastic head strap started cracking apart ,I was flying around 70 hrs per month whch would be pretty average use for a working pilot. I returned them under warranty and went straight back to my DC's. I have also used the Bose headsets, same thing..plastic components cracking, mike booms becoming loose..they are a nice headset however I think they are really built for guys flying 100hrs a year so to speak..my opinion is they don't quite stack up to the every day wear and tear if you are flying a lot of sectors...stick with DC's and you'll have a good headset for years!
